I am currently working on a project to upgrade CO2 driers from an old Siemens S5-90u to a centralized Yokogawa Centum DCS system. I've never worked with Siemens S5 before, so some of the questions I'll be asking are likely to seem rather stupid to some of the wizards here, but without any manuals or documentation and only a hardcopy of the STL and CSF, I've hit quite a few snags...
First question:
When defining the time constant for a timer eg: KT 180.2, what is the format for the constant. Is the first part the time constant and the second the time base? If so, what are the time base definitions?
Like I said, pretty dumb question, I know, but any help would be greatly appreciated.
Many Thanks,
W.
