Hello h_sadaka It depends on how much datapoints you have to send and if it should also be a bidirectional forwarding... If you only have a few datapoints and you should only send from Modbus to the PLC then you can use a script action in WinCC (VBS or C) and then only read tag value and write it to the other Tag. you could use a cyclic script (not too small cycle) or you use the readed tags as tag Trigger. Another way would be to communicate directly with the S71200 to the meter device and WinCC Read the Data from DB such as this LINK Bye Murof |
