The TCM18 Data
Highway Communications
The TCM18 is provided with two RS485 communications ports. These ports allow
for communication through Modbus ASCII or RTU protocols to a PC workstation
and/or to the facility distributed control system (DCS). The TCM18 is also provided
with an auxiliary 24 Vdc power source which can power optional communication
converter modules which will accept the TCM18 data highway information and con-
vert it to an alternate data stream protocol. Through these communication links,
most of the operating parameters which are programmable at the module can be
accessible at the central PC workstation, DCS system console, or other mobile in-
terface devices.
For communications linking information between the TCM18 and a PC workstation,
refer to the TraceView™ Network Explorer Operating Guide.
For communications linking information between the TCM18 and a DCS or other
network modules, refer to the TCM18 DCS Communication Guide, 50310.
