MOD 30ML Multiloop Controller
PRODUCT DESCRIPTION
1.4.12 2020N Remote I/O Interface Module
Remote Input and Output Modules expand the I/O capability of a MOD 30ML Multiloop
Controller to a total of 100 discrete points. The remote modules communicate to the
controller over the CS-31 Remote I/O Network, an RS-485 bus which connects the remote
I/O base units to the 2020N Remote I/O plug-in module. This module is not required to reside
in a communications slot, leaving the two communications channels on the controller open
for host or peer-to-peer communications. See Section 4.3.7 for remote I/O interface
connections. Remote I/O digital connections are described in IB-23C601. This module uses
the RIO block for configuration. A maximum of 2 RIO modules are allowed per instrument.

COMMUNICATIONS MODULES
The descriptions included in this section give a brief overview of the functions and features of
the communication modules. These modules can be used to add a second communication
channel to the MOD 30ML.
1.5.1 2030N ICN Communication Module
The ICN Communication module provides Instrument Communication Network (ICN)
communications capability for the MOD 30ML Multiloop Controller. The ICN is a proprietary
network that allows peer-to-peer communications between the controllers and can be used
with the MOD 30 Instrument line. It also uses a communication link to a computer running
the configuration or operator interface software. The ICN Baud rate is 31,250 bits per
second. The Model B ICN requires an external terminator such as the 2030F ICN
Terminator.
