Digital Output Relay Modules Low Voltage DO Relay Modules: The DO Relay modules have 8 or 16 outputs. There are two types of DO relays: Electrically Energized (EE) - the outputs return to the non-energized state in case of power off or module failure. Magnetic Latch (ML) - Relay outputs are magnetically latched, the outputs maintain their state in case of power off or module failure.
Digital Output Relay Modules between the required position and the back indication signal is reported to the CPU and is available to the user program. In some applications it is necessary to inhibit relay output operation when attending the site for safety reasons. In all DO relay modules, it is possible to inhibit all relays per DO module.
Digital Output Relay Modules DOs will keep the last value they had at the time they were frozen. Freeze mode enables testing the inputs and outputs while the user program is running. Note: In systems with I/O expansion, the power supplies on I/O expansion frames can be attached via DC cable to the power supply on the previous I/O expansion frame in a daisy-chain manner, or directly to the main power supply.

I/O Expansion The ACE3600 RTU includes the option of expanding the number of I/O modules controlled by a single CPU module on the main frame. The I/O expansion frames can be co-located with RTU on the main frame (installed in the same 19” rack or cabinet) or distributed in the same site (up to 50 meters from the main frame.) I/O expansion is based on a 100 Base-T full duplex Ethernet connection between the CPU module and the expansion modules.
I/O Expansion the main frame. Accessories such as a mobile radio, battery, etc. are attached to a separate optional 19” chassis. Radio/Batt. Chassis Main Frame (optional) Main PS (AC/DC) CPU3640 Crossed Cable LAN Cable Expansion Expansion Module I/O Frame ACE3600 I/O Expansion – Single Frame Example The figure below provides a general view of an ACE3600 CPU with a single I/O expansion frame.
I/O Expansion Note: The number of expansion power supplies that can be cascaded to the power supply on the main frame is limited. When required, optional DC or AC power supplies should be installed on the expansion frames to meet the accumulated power consumption and voltage level requirements.
I/O Expansion I/O Expansion Frame An I/O expansion frame always includes an expansion module to enable the CPU in the main frame to communicate with and control the expansion frame and its I/O modules. The expansion module is provided with each expansion frame (model F7510). Like the ACE3600 main frame, the I/O expansion frame can contain 3, 5, 7 or 8 I/O slots.
Expansion Power Supply Module The expansion power supply module (10.8-16V DC) extends power from the power supply on the RTU’s main frame to the I/O expansion frame, or from one I/O expansion frame to another. Note that this module is provided as default power supply in each I/O expansion frame unless replaced with the other power supply options.
Expansion Module The expansion module provides an interface from the CPU module (either directly or via the expansion LAN switch) on the ACE3600 main frame to the I/O modules on the expansion frame. This enables the CPU on the main frame to control the I/O modules on the expansion frame and process the gathered data.
60 cm (Motorola p/n V529 / FKN8561A) - This cable is used for local connection of the main CPU to the expansion switch, or connection of the first LAN switch to the second, if such exists.
I/O Expansion The Expansion module discovers the main CPU (MCPU) via UDP/IP (broadcast). Expansion Loader Discovery succeeded- obtained self and MCPU IP address? 1. Loads the Firmware Image into RAM from the MCPU (using TCP). 2. Turns off all LEDs and runs the loaded Expansion Firmware Image. 3.
I/O Expansion Expansion Module Power-up and Restart The MCOM LED on the expansion module indicates the connection status between the expansion module and the main CPU and expansion frame initialization progress. The main CPU expects the expansion frames to complete the initialization within a configurable period of time (60 seconds default).
CPU memory. The RTU error logger information can be retrieved using the STS Error Logger utility. The expansion LAN switch option includes a 60 cm Ethernet cable (Motorola p/n V529/FKN8561A). Use this cable to connect from the Eth1 port on the main CPU to the Eth1 (M) port on the expansion switch.
I/O Expansion One of three Ethernet cables can be used to connect an Ethernet port on the expansion LAN switch to an expansion module in an expansion frame. If the system includes one switch (for up to seven frames), ports Eth2-Eth8 are available. If the system includes two switches (for up to thirteen frames), ports Eth3-Eth8 are available on the first switch and ports Eth2-Eth8 are available on the second switch.
RTU I/O Expansion - Power Considerations When planning a co-located multi-I/O expansion frame configuration (where all frames are located in the same enclosure or 19” rack), it is possible to cascade the power supplies of the expansion frames to the power supply in the main frame. In the system design stage (before ordering), it is critical to calculate the maximal accumulated power consumption from the main frame power supply (or from a power supply located on an expansion frame which is not an expansion power supply) to make sure it is not...
I/O Expansion Each cascaded expansion power supply gets a lower input voltage from the preceding power supply. The voltage drop is a function of the expansion power cable resistance and the current flowing through the cable (which is the accumulated current of the expansion frame and all the following expansion frames cascaded to it.) The paragraph below shows how the input voltage of a cascaded expansion frame can be calculated.
I/O Expansion The general equation for Vx is: Vo depends on the power supply configuration. Vo should be 13 V DC when the backup battery option is not used. If the battery option is used with the main power supply, during power fail Vo depends on the battery voltage (which may be below 13 V DC).

Communications The ACE3600 (as well as MOSCAD family RTUs) facilitates the establishment of a highly sophisticated hybrid data communication network for SCADA that utilizes a variety of radio and/or line communication links. Radio links may include conventional (VHF, UHF, 800 & 900 MHz), analog trunked, digital trunked, and both analog and digital microwave radio technologies.
The MDLC protocol is discussed below. MDLC Protocol The MDLC protocol is a Motorola SCADA protocol that is based on the Open System Interconnection (OSI) model recommended by the International Organization for Standardization. MDLC utilizes all seven layers of the OSI model. This protocol is designed for optimum operation in SCADA systems which operate with diverse communication media such as two-way radio, line, LAN, etc.
Communications from the technical constraints and complexities of network operations thus allowing the intended application to be the item of focus. MDLC uses a semi-synchronous data format on two-way radio and an asynchronous format on wirelines. It is not correct to refer to message size in byte notation because of the 16-bit architecture;...
Communications The lower three layers of the MDLC protocol stack are commonly known as Network Services. These layers only are used when communicating with intermediary sites which make it possible to pass any data through the system and not require the total system to know the details of the data.
This is the messaging method most often used by Motorola RTUs because it uses the shared communication medium properly.
Communications Communication Links The system may support a network comprised of a nearly unlimited number of links. The RTU supports a variety of communication media, protocols and data speeds, as detailed below: • Serial RS232 ports, up to 115.2 kbps, supports: –...
Communications IP Ports). The RS232 ports may operate at data speeds up to 115.2 kbps (depending on the total wire length). RS485 Ports On ACE CPU modules, Serial Port 1 (SI1) can be configured as RS485 port. Additionally up to two RS485 Plug-in ports can be installed on the CPU module (on PI1 and PI2 plug- in ports).
Communications • Cable characteristic impedance: Distributed capacitance and inductance slows edges, reducing noise margin and compromising the ‘eye pattern’. Distributed resistance attenuates the signal level directly. • Termination: A long cable can act like a transmission line. Terminating the cable with its characteristic impedance reduces reflections and increases the achievable data rate.
Communications IP Ports (MDLC over IP) ACE3600 RTUs can use IP (Internet Protocol) technology to interface to advanced radio infrastructure (e.g. TETRA or GPRS) and to standard private IP networks. Most benefits of the MDLC protocol are preserved. MDLC and IP networks can be integrated in the same system, as networking properties are preserved.
Communications 4. IP Gateway connected to LAN. An IP Gateway (IPGW) serves as a front-end for a TCP/IP-based SCADA central and enables it to communicate with remote RTUs. The IPGW uses a direct LAN connection to the radio infrastructure. It cannot be connected with a packet IP Ports (IP LAN/WAN ports) data modem/radio over PPP.
Communications IP Conversion Table Enhancements An IP conversion table can be assigned to each RTU/FEP. It maps each site ID+link ID (port) to an IP address. The link ID column supports multiple MDLC over IP ports per RTU. Each link ID uniquely identifies the port/IP connection of that RTU. The table enables the MDLC over IP port to transmit MDLC packet to its destination based upon its site ID and link ID (port).
Communications Configuring NTP Servers An Ethernet or RS232 PPP port can be configured for NTP protocol (NTP is UDP port number 123.) In this case, the RTU will retrieve its time from a set of NTP servers specified by the user. The clock offset between the RTU and these servers depends on network delays, and may be up to 100 milliseconds in some wireless media.
RTU when using this connection. • MDLC via Tetra radio. This is similar to Standard modem. See MDLC over Tetra Setup for configuration details. When using a Motorola radio (e.g. MTM800), no modem configuration file needs to be downloaded.
Communications • Static IP address mode • Dynamic (DHCP) With static IP address mode, the user is required to set the link ID, IP address, subnet mask and default gateway. If DNS or NTP servers are required, these must be defined as well.
Communications MDLC over LAN/Ethernet The ACE3600 RTU can communicate over Ethernet media, via the onboard Ethernet port or 10/100BT plug-in ports. The figure below illustrates an example of a SCADA system with IP Gateway and ACE3600 RTUs connected to Ethernet LAN: SCADA Central Ethernet 1...
With SCADA systems, ACE3600 RTUs can be connected to an ASTRO IV&D radio. The ASTRO infrastructure (R6.4 or higher) and radio must support integrated voice and data (named IV&D). This is relevant to Motorola subscriber data radios such as the XTL5000 mobile and XTS2500 portable.
Communications Unlike other infrastructures (such as iDEN and TETRA), this IP address and radio unit ID cannot be retrieved for diagnostics from the radio. Instead a dummy IP Address is provided by the radio as it is configured using the CPS (Codeplug Programming Software).
Communications Certain configuration steps are performed on the radio itself using the CPS and in the infrastructure using the UCM tool. See the relevant radio documentation for more information. There are two types of hardware interface between the RTU and the radio: For a mobile radio such as the XTL5000, the interface is comprised of a radio data cable over RS232.

RTU, since they all have the same IP address. Other modems such as Motorola g18 do not have an internal IP address; in this case several MDLC over IP ports can be configured to connect with them.
Communications MDLC over GPRS Network An RTU can be connected to GPRS (GSM) network through a LAN or through a radio. An IP Gateway or an RTU with an Ethernet port can be connected to the LAN. In the figure below, the SCADA central and IP Gateway are connected via LAN to the GPRS infrastructure.
Note that before downloading the modem configuration file for GPRS, you need to change its APN according to your operator instructions. The APN (Access Point Name) is an address such as intranet.motorola.com. The APN defines the security and capabilities set by your provider for your SIM cards.
Communications IP Conversion Tables The IP conversion table is created in the ACE3600 STS using the IP Conversion Table Manager. Note that unlike the network configuration, there is no default, and any IP conversion tables must be created manually. The IP conversion table maps sites in the system (site ID+link ID) to IP addresses or host names.
Communications In the example above, two sets of IP conversion tables should be created and the FEP’s Table should be assigned to the RTUs: The following IP Conversion Table should be loaded to the RTUs: Site ID Link ID IP Address or Host name LINE1 10.5.1.160 LINE2...
Communications Firewall The ACE3600 Firewall enables the user to define a variety of firewall protections. The firewall is configured and activated in the ACE3600 STS site configuration per site, for all IP ports in the site. The user can specify the list of IP addresses to accept, i.e. the list of IP addresses allowed to pass through this firewall.
Communications MDLC over Dialup Modem Configuration The ACE3600 can be connected to dial-up modem. The user can configure the modem from the RTU using the MDLC over Dialup port. A configuration modem string can be defined in the Physical Layer to configure the modem. The modem configuration file enables the user includes the configuration modem string and other AT commands.
Radio Communications The ACE3600 RTU is designed to operate with various Motorola conventional and trunked radio transceivers (see table below). Other Third Party conventional radios can be interfaced to the ACE3600 using the radio modem ports using DPSK 1.2 kbps modulation (for more information consult Motorola support).

FM transceiver’s oscillator to most effectively use the radio bandwidth. Motorola refers to this modulation technique as DFM; in the U.S. this is also described by the FCC as an F1 emission. The figure below shows the modulation sideband created by DFM.
Communications In the U.S. the FCC’s rules for Fixed Secondary Signaling and for Telemetry operations require data not to interfere with voice operations—the data message must wait until the voice message is finished. This is a practical matter also—if a data message were attempted simultaneously with any co-channel message, there is a high probability that the data would be corrupted and throughput would be zero.
Communications Sum of the Highest Modulating Frequency plus Deviation shall not exceed a stated maximum. For most channels, that maximum is 2800 Hz but on two frequencies (173.2100 and 173.3900 MHz) the maximum is 1700 Hz. The splinters were exempt from all Refarming actions and still require a 5K60F2D emission designator.
Communications Analog Trunked Radio Systems In an analog trunked radio system, any unit that needs to send a message, requests, and is assigned to, a channel by the trunking system controller. The ACE3600 RTUs are typically clustered into a single trunked data group and are managed by the trunking system controller as a single entity.
Conventional Radio Interoperability Introduction Since the first MOSCAD RTU was introduced to the market, various models of Motorola conventional radios had been used with Motorola RTUs. In cases where new RTUs are added to existing systems with newer radio models, or when legacy radios are replaced with newer models, it is important to make sure the radios can interoperate in the same system.
Parameter might be longer. In this case, the parameter setting in the system is determined by the RTUs/FEP radios and the repeater’s performance. For technical support concerning setting parameters in system with F1-F2 repeaters, please contact Motorola technical support.

Communications Communication Network The ACE3600 system network consists of RTUs communicating with one or more computerized control centers and/or with other RTUs. Each control center is connected to the communication network. The system can be relatively simple, comprising several RTUs and one control center. It can be modularly expanded to a more hierarchical system, where several sub-systems (comprising intelligent RTUs and/or sub-centrals controlling their peripheral RTUs) communicate with a central computer.
Communications communication with the central. It also can act as a communication node (an interconnection point between two or more different links) while performing its other tasks. The RTU network uses the MDLC protocol, which incorporates all seven layers of the OSI model adapted for SCADA.
Communications Network Configurations The ACE3600 system supports both simple and complex communication networks. The following sections describe various configurations from different aspects. Simple System A simple system, comprised of a central computer and RTUs connected over one communication link, is shown in the following figure: Central Computer IP / RS232...
Communications The FEP in the system illustrated above serves as a network node between link RADIO 1 and link LINE 1. Configuring the FEP to have access to two different links enables it to serve as a node between these links. The MDLC protocol permits RTU-to-RTU communications without the intervention of the central computer.
Communications RTU 9 (Site ID = 9) is configured as a Store & Forward repeater. It performs data exchange between units that operate on the same frequency but are unable to communicate directly for reasons of path and propagation. Any RTU in zone 1 may communicate with any RTU in zone 2 via this repeater.
Communications The schematic representation of this system is shown below. The system assumes that the two nodes, RTU 15 and RTU 40, cannot “hear” each other. They communicate via the FEP, which is also a Store & Forward node. This system, therefore, consists of four zones and three nodes (RTU 15, RTU 40, and FIU).
Communications In this case, the two nodes do not communicate through the FEP. Therefore, the FEP does not serve as a node in the system. Note that the communication between RTUs in different zones passes only through two nodes. MDLC Encryption Overview Encryption prevents any non-authorized party to communicate on MDLC network.
Communications Both a non-encrypted RTU and an encrypted RTU can serve as an MDLC network node for encrypted or non-encrypted RTUs. Encryption Keys A set of Encryption Keys is defined for the system using the MDLC Encryption Tool. The Keys File (KF) is saved and then downloaded to the IP Gateway and to the RTUs using the MDLC Encryption Tool.
Communications When an RTU is first configured and stars up (cold start in MOSCAD and MOSCAD-L RTUs), the key index is set to ‘0’ (non-encrypted mode). Encryption is then activated by changing the Active Key index to a number other than ‘0’ (1-9). This is done using the MDLC Encryption Tool.
Communications Security Administration Tool The Security Administrator Tool, provided with the MDLC Encryption Option is used to control access to the MDLC Encryption Tool and files. Using this tool, the administrator can define users and groups, and grant permissions to authorized personnel as necessary.
Clock Functions and Synchronization RTU Clock The ACE3600 RTU has one time source, an internal system clock which is in microsecond resolution. This time source is updated using a backup source of the RTC hardware component - Real Time Clock (seconds accuracy). In addition, external clocks, such as GPS and NTP servers can be used as a time source.
Clock Functions and Synchronization In ACE3600 RTUs, a new MLDC extended time synchronization can be enabled which includes the synchronizing RTU’s password. In this case, all RTUs in the system must use the same password. This extended time synchronization also enables synchronizing two RTUs in different time zones, and better accuracy than the MOSCAD MDLC legacy synchronization.
Clock Functions and Synchronization system table, it also changes the RTU time and date. For more information on the Time & Date database system table, see Appendix C: Database Tables and Data Types in the ACE3600 STS User Guide. The user can update the same Time & Date database system table (HH:MM:SS) using the Application Programmer database monitor function.
Clock Functions and Synchronization RTU (usually FEP) can act as a server. This enable setting its time via MDLC time sync, for example, and having other RTUs specify it as an NTP server and obtain their time from it. NTP synchronizes clock both in time and frequency. In time means it make its clock offset as close as possible to the server.
Clock Functions and Synchronization The accuracy of other clocks is judged according to how “close” a clock is to a reference clock (the stratum of the clock, the network latency to the clock, and the claimed accuracy of the clock. The accuracy of NTP thus depends on the network environment. Because NTP uses UDP packets, traffic congestion could temporarily prevent synchronization, but the client can still self-adjust, based on its historic drift.
The specification also defines a standard mechanism to access named data items contained in an OPC server. Motorola used the OPC specification to build the M-OPC server. This server enables exchange of information over the communication system between SCADA managers (or any other application) and Motorola RTUs.
SCADA managers. • Support of special features unique to Motorola RTUs. • Support of the MDLC protocol and all Motorola RTU types, i.e., ACE3600, MOSCAD, MOSCAD-L and MOSCAD-M. The M-OPC server uses OPC Data Access (DA) V2.05. The server enables the clients to organize the field data according to the OPC logical object model and read/write data either synchronously or asynchronously.
API is also provided which the system engineer must use to develop a driver between the programs in the server that require data from the IP Gateway and the IP Gateway itself. Contact your Motorola Data Specialists to determine if a driver is already available for the host hardware/software being used.
SCADA System Components has an equivalent ModBus address according to some very simple yet rigorous rules; therefore, the database in the MCP-M may easily be read, or written to, by the SCADA Manager. The MCP-M’s database is kept accurate by any combination of the communication modes discussed in the Communication chapter.

Appendix B - FCC Information Spectrum and Regulatory Update The Federal Communications Commission (FCC) has made a series of changes over the years to the rules and regulations that govern the use of frequencies that constitute the VHF and UHF bands. They affect in several ways how MOSCAD devices are used on traditional, conventional two-way radio channels.
Appendix B - FCC Information Spectrum and Regulatory Update were channels licensed for data (or voice) use on a “secondary” basis; that is usage could not interfere with operations licenses on the primary channels. Through the adoption of the refarming decision, the low-power, secondary offset channels have been converted to primary channels with a maximum bandwidth of 12.5 kHz.
All Motorola radios carry a F3E designator, not all of them are also certified for F3D or F1 or F2 operation. This interpretation says MOSCAD can use radios only certified for F3E operation.
1. Location Description Code: Fixed, unless applying for certain frequencies that allow Mobile designations to be used for fixed sites, typically with power and/or antenna restrictions. Various Motorola radios can be licensed as mobile, but the MOSCAD units are almost always at fixed, permanent locations.
