Hi all, I'm a new user here. I'm looking at a project that needs to be up and running pretty fast, so I've been scanning manuals and trying to fit things together. I have a question that you folks of experience can help with.
In the "old days", depending upon the type of PLC & HMI that was used, you had to set-up data reads and writes to communicate. From what I've uncovered so far, it looks like when using C-More, and a 350 CPU, the only requirement is that C-More sets the tagname database information, and then it can read or write to the specified locations. Is it that easy, or did I miss something? (if so, please point me to a manual or user guide location)
Does the PLC logic need to do anything to initialize the com port?
I'm used to grouping data types that are exchanged between HMI and PLC, as much as possible. That still makes sense from a through-put sense, yes?
Thanks for any help!
