Alright, here is what I know.
In the lab we are building a new OSIsoft PI system and need to inject some real life data into the machines for testing. So I got a SLC500 kicking around, threw a few cards into it and loaded
RSLogix500 2.57.0.0
and
RSLinx Classic Lite 2.50.00.20
Connected to the SLC500 via DH+ to a A-B communications interface box that converts it to serial to connect to COM1 of my laptop
Was able to connect, build a simple ladder program to bring in some switches and an analog value etc all is well I have raw data coming in and being stored in the PLC.
So, looking online I see it mentioned if you have RSLinx 2.1+ you can set it up as a OPC server, so checked and yep there is a option when I right click on the PLC symbol in RSWho, "Configure New DDE/OPC Topic" and setup a topic, default settings, saved/updated the topic.
Then I opened up "OPC Test Client", File-New, "RSLinx OPC Server" then click OK and I get an error "Connection to Server Failed. ~RSLinx OPC Server"
So, looked it up and found some common problems with DCOM settings so I went in and set RSLinx, RSLogix, and OPCenum all to allow basically everything it's wide open. Still the same issue
So I checked RSLinx and under the DDE/OPC tab I checked the communication event log and there is one up that says "Remote OPC Connection attempted on a none RSLinx Classic fateway machine" so that's odd... I checked also under the DDE/OPC tab the "Active DDE/OPC Topic/Item List" and the list is blank...
SO... guessing right now my OPC isn't up and running and therefore I can't connect to anything. But my question is what steps do I need to take or what software do I need to buy to get this system rolling? I thought I did everything right but I guess not...
Any help would be appreciated
