The CNOS-001 is a serial port expansion module for Schneider Automation's TSX Compact PLC. It takes advantage of the new Compact communication channel. The module gives the Compact two additional serial ports that are switch-selectable RS-232 or RS-485. It is configurable as either an option module or an I/O module.
The CNOE-800 is simultaneously a router, and a protocol converter. Internally, the CNOE-800 has 3 ports: the two serial ports, and the PLC "port" (via backplane comms). The serial ports speak Modbus RTU or ASCII (master or slave), SY/MAX, PLOGIC, RNIM, mixed Modbus/SY/MAX, and others. Messages from any of the three ports can be routed out any other port. As messages move between the ports they are translated from one protocol to another. Using an MSTR instruction, the PLC can issue:
The two serial ports have RJ45 connectors and are independently swich-selectable RS-232 or RS-422/485. Ports are independently configurable as to mode, baud rate, and etc. External serial devices can:
Multiple CNOEs can work in a single rack. No web pages are served by this module. Modules come with a user manual and configuration software on CD, 1-year warranty and 1-year free firmware upgrades.
