Hi Khalid,
In order to establish communication with A-B PLC 2/30 and be able to read /write data from/to this PLC using OPC server we have established a DH+ network using a 1785-KA3 Module on PLC side and a DLPCIe card on PC side. As OPC server we used RSLinx to read/write data from/to PLC. To achieve this goal we also needed to introduce a communication zone to PLC by adding some rungs (snapshots of rungs from Programming Terminal can be provided). After adding these rungs and restarting the PLC, using RSLinx on PC side, the PLC node has been successfully and automatically detected by the software (RSLinx) but the problem is that when we try browsing any data on the PLC using any OPC client (like OPC Quick Client,…) we are not able to see any data available about any block or bit of PLC. Can you help us?
Regards,
Yasir

Hi Khalid,
I need your help regarding communication of Allan Bradley PLC 2.30 over DH+ with RsLinks.Case is mentioned below.
In order to establish communication with A-B PLC 2/30 and be able to read /write data from/to this PLC using OPC server we have established a DH+ network using a 1785-KA3 Module on PLC side and a DLPCIe card on PC side. As OPC server we used RSLinx to read/write data from/to PLC. To achieve this goal we also needed to introduce a communication zone to PLC by adding some rungs (I can send snapshots of programming terminal if needed). After adding these rungs and restarting the PLC, using RSLinx on PC side, the PLC node has been successfully and automatically detected by the software (RSLinx) but the problem is that when we try browsing any data on the PLC using any OPC client (like OPC Quick Client) we are not able to see any data available about any block or bit of PLC. Does anyone have any idea about this task?
