Communication problem

Postby rolf.viktor » Wed Aug 08, 2012 6:50 am


i have a problem and i don't know how to rezolve it. I have a Twido PLC(model: TWDLCAA16DRF), with 2 serial port(RS485), one energy meter(Algodue UPT210), one LED Display, and one sielco sistemi SCADA software to collect data from energy metter and to give some commands to the PLC. I connect LED display at port 2 because it not suport modbus protocol,energy metter i connect at port 1, i can access data separately in Sielco and Twido but when I try to read data from algodue simultaneously in Twido and Sielco one of them can not read. The problem is I consider both master but modbus protocol support just one master devices. One solution is to configure PC with sielco sistemi to be slaves but I do not know what settings need to be made. Please help me...
