I/O AND COMMUNICATION MODULE BLOCKS

I/O and communication module blocks are not part of a loop scan group. I/O
module blocks can be placed anywhere in an instrument strategy as a
convenience to the user. The ICN and MSC communication module blocks are
available outside of loop compounds only and are placed somewhere at the
instrument level.

Place your I/O modules either in a loop with their associated input functions
(connection made at same level) or together at the instrument level so they can
service different input functions (requires more connections through CIB blocks
at different levels). If you decide to place your I/O modules in a direct
connected compound (Section 5.6), you can treat the CPD block as a
centralized I/O connection source. Use the MODOUT connection of each input
module to create a connection to MODIN of a matching input function. Use the
output module INPUT connection as you logical source pointer. There are 32
available module slots that can be filled on a MODCELL Multiloop Processor
(use the I/O module layout icon to assign slots).

5.4.1 Communications Module Block Selection

From the instrument level Library Display, select Communication to make the
Communication modules available as resources. The Communications
modules types are:

ICN

Instrument Communication Network Module. Reference IB-23G600
Section 3.7. This block links configured lists, input and output
communications blocks, notification message blocks and supervisory
message blocks to other devices on the ICN through the ICN module.
The 2030N ICN Communication module can be located in the following
slot pairs (ICN numbers based upon assigned occurrence in .CRF file).

Slots: ICN1 31-32; ICN2 28-29, 29-30; ICN3 25-26, 26-27, 27-28

MSC

MOD Serial Communication Module. Reference IB-23G600 Section
3.26. This block links Modbus lists to Modbus devices through an
RS232 or RS485 module. The MSC module can be located in the
following slots.

2033N RS232, 2034N RS485 Communication Module (two slots)
Slots: MSC1 31-32; MSC2 28-29, 29-30; MSC3 25-26, 26-27, 27-28
2032N RS485 Communication Module
Slots: MSC1 32; MSC2 29, 30; and MSC3 26, 27, 28
