I would like to grab PLC data (SLC5/03) and grapf it on computer. I assume I will be connecting to 232 port on processor. Any ideas on how to get started?
Well when you know for sure let us know, but any ideas at this time would be sheer speculation.
To get more information or help you will need to be more specific with your information.
If you are only communicating with one SLC you might want to use RSLinx single node, it's less expensive ($400) and will still let you communicate DDE with Excel or other windows programs.
