Lonworks Board; Local Instrument Link (Lil) Network Board; Ethernet Board - Siemens Moore 353 User Manual

UM353-1 Circuit Description
Relay 1 and Relay 2 are triggered by the off-board MPU to provide relay contact type outputs. Each SPDT relay
output can be connected in a normally open or normally closed contact state.

13.4 LonWorks BOARD

The LonWorks Board provides additional I/O when needed for multiple-loop applications, advanced control, or
batch sequencing. This board uses the popular LonWorks (LON stands for Local Operating Network) protocol for
high connectivity via a high-speed digital fieldbus to a large selection of standard I/O products. LonWorks remote
I/O products include many analog input and output options as well as digital inputs and outputs using relay or solid
state technology. This board plugs into the Controller Board via two connectors. An 80 pin pass-through connector
is also available for stacking additional option boards.
The LonWorks Board has an integrated circuit containing three processors, two timers, RAM, EEPROM, parallel
and serial ports and a network communication port. The board communicates with the Controller Board via a
parallel MIP interface. The MIP interface uses a token passing scheme so only the token holder can initiate a data
transfer. The board also connects directly to a remote network using a free topology transceiver that operates at a
rate of 78 kbps and connects up to 64 nodes over a twisted pair (see Section 5.0). The network wiring may be in a
bus configuration or wired in any combination of bus, star or loop topologies.

13.5 LOCAL INSTRUMENT LINK (LIL) NETWORK BOARD

An optional Local Instrument Link (LIL) Network Board is available in place of the Modbus communication
network to provide higher speed networking and peer-to-peer communication between controllers. The hardware
architecture is designed to accommodate other emerging fieldbus technologies. This includes both field
communications that may require lower power for intrinsic safety and also higher speed for interplant networking.
The LIL Board plugs into the controller board via two connectors. An 80-pin pass-through connector is also
available for stacking additional option boards. The LIL Board communicates with the main Controller Board via a
32K, 8-bit Dual Port RAM. Two LED's on the LIL Board indicate serial transmit and line activity.
Global LIL function blocks (AIL, AOL, DIL, DOL) can be configured to provide communication between 353
controllers as well as connectivity to other LIL products, such as the Models 352, 351 and 382, over a twisted pair
network. The total number of global function blocks will be limited by the number of global channels available.
Information on LIL network communications and Data Mapping can be found in Sections 6 and 7.

13.6 ETHERNET BOARD

Ethernet communications is available in place of Modbus and LIL communications. This option enables peer-to-
peer Ethernet communication (using embedded Modbus RTU protocol) with other Moore controllers, Procidia i|pac
controllers, and other devices having Ethernet (embedded Modbus RTU protocol) functionality. Ethernet
communications requires an optional Ethernet board and MPU Controller firmware V2.4 or higher.
The Ethernet board supports uploading and downloading of controller configurations over the Ethernet LAN. Data
can also be acquired from remote servers for the purpose of archiving and/or data mining. The Ethernet-Modbus
Bridge in Figure 1-2 accepts an Ethernet data command from the controller and outputs an equivalent Modbus
command. The returning Modbus data is embedded by the bridge in an Ethernet packet to be sent to the requesting
controller.
The Ethernet board plugs into and communicates with the controller board via an RS485 serial port. Board output is
10/100 Base T using an RJ45 connector. Ethernet function blocks are provided in V2.40 and higher MPU Controller
board firmware. When an Ethernet board is installed, rear terminals NCA and NCB are disabled.
