Hi
I wonder how you would go about troubleshooting OPC DA comms between 2 computers on the same network (obviously 1 being server and the other client). The only thing know is that the ping is working between both PCs. What is the best path and the least amount of steps ? i have a feeling it should take 30min instead of several hours which does sometimes happens. Apart from that there are several questions related to the main question of the ideal troubleshooting steps:
1 I thought OPC enum absolutely necessary for OPC DA to work or its possible to work even without that?
2 What are preferred OPC DA clients to start connections - i have a feeling that kepware is good but rockwell RSI even better (tiny program which has only the basics needed )
3 DCOM setting is the main issue to get it right but is there any way or tool to make sure that they were done right (other than connection working)
4 Are there any tools helping in the troubleshooting steps of OPC DA - somebody mentioned matricon tool?
5 Is reading opcfundation docs the best way to learn the theory ?
Regards
