Hello everyone!
How do historians really work? I have not really attended any vendor training *cough* advertisements *cough*.
What options of historians exist? What is the data replay like? Is it only a textual log, or can this also replay ladder logic/ functional blocks?
Is it worth it really? Our plant already has an MES system for basic error proofing, but not to record all I/O.
Thanks!
