Dear Sir, Ihave system CPU-3152DP with CP-341-RS485. i want to configure this CP341 over MODBUS. I have confire two devices i.e. one power meter and one Proximity module(KATLAX make). i am facing one problem that whenever i am connecting only power meter then i get communicated over MODBUS satisfactorily. but when so ever i am connecting Proximity Module, i am not getting data from the Proximity Module. Proximity module is giving only one register(i.e. 16 bit) information whereas powermeter having 64 registers to send over modbus. Power meter is communicating very well over MODBUS. i am checking the data at the Proximity Module end with MODSCAN software. i found that it is giving data perfectly. i am also getting trasmit and receive LED(given on CP341 MODULE) whenever i am connnecting Proximity Module over MODBUS. but still i am not getting data in my PLC. PLease, note that the communication is taking place over MODBUS with 2400 bps baud rate, parity---None, Stopbits-1, Data bits-8. What may the reason behind this. Please, guide me.
