The connector marked TER is used to connect any device which supports Uni-Telway protocol, in particular devices which do not have their own power supply (RS 485/RS 232 connector cable converters,
TSX P ACC 01 isolation device, etc).
The connector marked AUX (only on Premium PLCs other than TSX P57 554/5634/6634) only enables devices which have a power supply to be connected (e.g. man-machine interface console, third-party devices, etc).
The terminal port has three function modes:
Illustration:
NOTE: For Premium PLCs with two connectors (TER and AUX), the operating mode defined in configuration (master Uni-Telway, slave Uni-Telway, character mode) is the same for both connectors.
According to the operating mode selected in configuration, the terminal port is used to connect the following:
-
Premium PLC programming and adjustment terminals
-
man-machine interface devices
-
another PLC, using the TSX P ACC 01 connection device
-
Uni-Telway devices (sensors/actuators, speed controller, etc.)
-
printer or control screen (link in character string mode)
-
modem
NOTE: Connecting a Premium/Atrium PLC slave to a UNI-TELWAY Bus requires the use of a TSX P ACC 01 device.
