2-Wire systems are typically used for low cost emergency stop systems or for monitoring systems that don’t require an emergency stop function such as a mine wide gas monitoring system. If the iMAC2 Controller emergency stop function is not required, the EOL module is not required, however an EOL module is still recommended for providing fieldbus diagnostic functions. -

Ampcontrol has a number of optimised iMAC fieldbus cables available to cater for your specific system requirements. Please consult with a qualified Ampcontrol applications engineer whom will be able to discuss and advise the most cost effective cable to meet your requirements. -
Page 16: Typical Installation
A host system (e.g. PLC) can communicate with the iMAC2 Controller via a configurable RS232/RS485 serial port using Modbus protocol. Data can be exchanged between iMAC2 Controller and host system via a read/wire Modbus register map. The iMAC2 Controller provides an Ethernet TCP/IP port that allows read- only access to the iMAC2 Controller’s Data Point Table. -
Page 17: Application Software
Temperature input modules are available for monitoring temperature via PT100 RTD sensor elements. 4.3.2 Output Modules Output modules can be controlled directly from input modules or indirectly via iMAC2 Controller application (SLP) software. In addition to general relay output modules, specialised output modules are available for duplicating the iMAC2 Controller Control and Auxiliary relays for redundancy and for passing belt sequence. -

Page 19: Networking
V4 – 10/18 Networking The iMAC2 Controller is equipped with two fieldbus ports, the L1 driving port and the L2 listening port. Controllers can be networked together by connecting the listening L2 fieldbus port of one Controller to the parent driving L1 fieldbus of another Controller. -

L2 Sequence Down Bit The “L1 Sequence Down Bit” and the “L2 Sequence Up Bit” are used by the iMAC2 Controller to initiate downstream and upstream sequenced starts (respectively). These bits can be set and cleared by the Controller’s application (SLP) software. This is in contrast to the “L1 Sequence Up Bit” and the “L2 Sequence Down Bit”... -

Page 22: Emergency Stop Sil Qualification
V4 – 10/18 Emergency Stop SIL Qualification The primary safety function of the iMAC2 Controller is that its Control Relay (CR) will de-energise on loss of communications with the iMAC EOL module. This allows an emergency stop system to be implemented simply by installing emergency stop switch contacts in series with the signal line that connects iMAC2 Controller to EOL module. - Page 23 The user is responsible for ensuring that the Ex ia Intrinsic Safety certification is maintained by complying with the “Conditions of safe use” outlined in the certificate IMAC2B009 V2 Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 22 of 53...

Page 24: Fieldbus Signalling Protocol
The iMAC system is not compromised by line capacitance or inductance because of a fixed transmission baud rate. The transmission speed is selectable so the data throughput can be optimised at commissioning for the particular system type. All iMAC modules are auto-bauding, automatically adapting to the iMAC2 Controller’s selected baud rate. -

Page 26: Power Supply
Figure 6.4: iMAC2 Controller Terminal Layout Power Supply The iMAC2 Controller requires a 24VDC power supply. Refer to Section 12 for further details. Digital Inputs There are three general purpose voltage free inputs on the rear on the Controller. These can be used as general purpose digital inputs to the application (SLP) software. -
Page 27: Relay Outputs
The Ampcontrol IP Protocol reads data from the General Buffer area of the Controller’s Data Point Table. The application software of the iMAC2 Controller must move data into these registers in a specific format to allow transfer of information between systems. Refer to the IMACB153 iMAC Controller Serial Communications Manual for more details. -
Page 28: Ethernet Communications Port
The L1 fieldbus port is the primary fieldbus port to which the iMAC modules are multi-drop connected. The iMAC2 Controller is orderable in one of two L1 fieldbus operating voltage options: 18V and 21V. The 18V option must be used for intrinsically safe systems, the 21V option is only recommended for large > 7km non-intrinsically safe systems. -

Page 34: Serial Interface Modules
Serial Interface Modules The iMAC System allows certain external equipment to communicate with the iMAC2 Controller through the use of Serial Interface Modules. These modules form a communication bridge between the iMAC System and compatible RS485 Modbus devices, allowing up to 16 Modbus Holding Registers to be read from a Modbus Slave RTU device and be transmitted to an iMAC2 Controller across the iMAC Fieldbus. -

Page 36: Installation
These instructions have been designed to assist users of the iMAC System with the installation of the iMAC2 Controller. Before the iMAC2 Controller can be installed, there are a number of points that need to be considered and understood to prevent incorrect or unsafe operation of the iMAC2 Controller or the greater system into which it is installed. -
Page 37: Mandatory Installation Practices
V4 – 10/18 Mandatory Installation Practices The following information must be adhered to when installing the iMAC2 Controller. Failure to adhere to this information may give rise to unsafe operation. Using the iMAC2 Controller in a manner that exceeds its electrical, functional or physical specifications, or in a way that is contrary to its operating restrictions, may increase risks to personnel and/or equipment resulting in injury or death. -
Page 38: Mechanical Arrangement
V4 – 10/18 Mechanical Arrangement The iMAC2 Controller is housed in a metal enclosure and is intended to be panel mounted. When panel mounted correctly using the supplied mounting brackets, the fascia gasket provides an ingress protection rating of IP55. The iMAC2 Controller must be mounted with the supplied gasket to maintain this IP rating. -
