The CNOS-101 is a serial port expansion module for Schneider Automation's TSX Compact PLC. The module gives the Compact two additional serial ports that are switch-selectable RS-232 or RS-485. The CNOS-101 includes an LCD screen and 5-button keypad which simplifies basic configuration such as setting the serial port mode and baud rate. The LCD also provides the ability to display status messages, serial and backplane statistics, and firmware revisions.
This module is a drop-in replacement for the Niobrara CNOS-001.
The CNOS-101 is simultaneously a router, and a protocol converter. Internally, the CNOS-101 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 CNOSs can work in a single rack. Modules come with a user manual and configuration software on CD, 1-year warranty and 1-year free firmware upgrades.
