The two TER and AUX ports on the TSX P ACC 01 device have the same standard functions as the TER and AUX connectors on Premium/Atrium PLC station processors.
-
The TER connector on the device is used to connect any device which supports Uni-Telway protocol, and in particular link up devices without their own power supply (RS 485/RS 232 cable converter, etc.).
-
The AUX connector on the device is only used to connect devices with a power supply (man-machine interface console, third-party devices etc.).
NOTE: The TSX P ACC 01 device is supplied from the TER connector on the PLC to which is it connected. As a result, the TER connector on the device enables devices with their own power supply (Magelis, etc) or without their own power supply (RS 485/RS 232 cable converter, etc) to be supplied.
If the user wants to connect the terminal port of a second PLC to one of the ports on the TSX P ACC 01 device, the AUX connectors (on the device and PLC) must be used to avoid power supply conflicts on the two PLCs.
