Invalid value for registry error while browsing for external database in ciect SCADA

sarath kumar

I am using citect scada 2018 and i am trying to connect scada to m580 plc through OFS factory server. I am able to communicate with OFS factory server and PLC but when i am trying to communicate Scada with OPC, while browsing for external database i am getting an error saying "Invalid value for registry" . How can i solve this problem

    I never had to browse for an external database using OFS.

    All you have to do is create an I/O device and use protocol OFSOPC (not OPC). For address use the name of the PLC you configured in OFS Configuration Tool. In OFS config make sure to use data dictionary.

    After this you can create Variable Tags in SCADA using the PLC variable name as address.
