Data Communication Module (DCM) TI 405 Series
The Data Communication Module (DCM) enables the TI Series 405 PLCs to interface with the
Operator Station. The DCM supports the Hostlink protocol either Master/Slave or Peer-to-Peer. In
the Master/Slave configuration, the Operator Station will be the Master device and the DCM will be
the slave device in both the Point-to-Point and the Multidrop configurations. The DCM has a serial
connection that will connect to the multi-drop network or directly point-to-point to the Operator
Station.
