Modbus and TSX Nano


Thread Starter



I have a TSX Nano connected to a PC com Modbus, that distances is the maximum one between both equipment, the manual says 200 to me mts.
Your problem is the distance over which an RS232 signal will properly operate. 200 feed, with good wire, is near the limit.

Check out web site for some good information on RS232 and RS485 wiring. To put it quite simply, RS232 and RS485 are like piplines. What goes into the pipeline is the protocol, like Modbus.

Another thing: the communication media of the TSX Nano connection is RS485. You must have a RS485/RS232 converter to establish a connection between a PC and your Nano PLC.
