COMMUNICATION BLOCKS
Communication module blocks define a physical interface port and are not part of a loop scan
group. The ICN and MSC communication module blocks are available outside of loop
compounds only and are placed somewhere at the instrument level. One of these modules is
required to talk to other devices on the network. Configuration activities such as download a
database, import a database or general activities for reading and writing instrument status
information all passes through a communication module.
Communication modules are selected from the instrument level Communication Library. The
Communications module types are:
ICN Instrument Communication Network Module. 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).
ICN1
31-32;
ICN2 28-29, 29-30;
ICN3
25-26, 26-27, 27-28
MSC Modcell Serial Communication Module. This block links Modbus lists to
Modbus devices through an RS232 or RS485 module. The MSC module can
be located in the following slots.
For the 2033N RS232 and the 2034N RS485 Communication modules, which require
two slots:
MSC1
31-32;
MSC2 28-29, 29-30;
MSC3 25-26, 26-27, 27-28
For the 2032N RS485 Communication module, which requires one slot:
MSC1
32;
MSC2
29, 30;
MSC3 26, 27, 28
