Hi, folks!
I'm banging my head against the wall again, trying to find a reasonable way to "see" 3 words in each of 4 PLCs (CPM2B, if it matters), beginning at IR 206...from a VBScript program running in a PC. I've done just enough VBScript to be dangerous, and probably not enough PLC programming even for that!
The idea is to make some decisions based on the values in those words, and that part I can handle, but geez, it'd be nice if I could say something like x = ReadPLC(Node_Num,Start_Word,Length), and get those words back!
Any suggestions, short of OPC Servers/Clients, or full-blown SCADA packages?
Thanks for ANY assistance, pointers, or words-to-the wise!
Joe
