nitinkakade Posted January 17, 2006 Report Posted January 17, 2006 Hi to all I am new to this forum,I am facing some problem in communication of PLC network. I am looking forward for your help My scheme is as follows(attached) I am able to communicate with 7 no. of PLC's but only one is not communicating(one incircled in RED) I am able to communicate Node no-1 and node no.-3 too,which are connected to Node no-2 via looping.(i had cross checked the Node Nos.) For communication(DH 485 Bus) I am using DF1 (i.e. RS 232 converted to DH 485 in Communication configuration on COM Port 1) using Net AIC 1761 and CP3 cable(because My DH485 port is connected to some other network). I had tried all the possible and suggested solutions for this. One thing remain is to change the CPU of PLC(some one suspects might faulty ports) Please help me out to solve this problem. nitin mrplc.doc Quote
