Controledge 900 I/O; Placing I/O Modules In The Racks - Honeywell ControlEdge 900 platform Hardware Planning And Installation Manual

ControlEdge 900 I/O

The configuration and operation of the I/O expansion network is
automatic, it is entirely under control of built-in private software that
resides in the CPM and in each EPM included in the ControlEdge 900
Controller system. The controller examines the control strategy stored
in its memory, verifies that the physical configuration (Rack Numbers
and I/O Module type- by Module Number) matches the stored control
strategy, and establishes communication with each of the I/O
modules in each of the I/O rack.

Placing I/O modules in the racks

Each I/O module is placed in an I/O slot in a rack.
The application cables are not supplied by Honeywell, and you
could prepare them by yourself.
CAUTION: The ControlEdge 900 Controller I/O expansion
network is a private network and the switch used for the
interconnection of the CPM and EPMs must not be connected to
any other LAN or WAN. Likewise, no devices other than the
ControlEdge 900 Controller components should be connected to
the switch. Failure to comply will cause communication failures
on the I/O expansion network causing I/O modules to go in and
out of their failsafe settings.
