I currently have two applications that require control of certain plant operations by time and date. What is required is a PC database that would write ASCII code to a PLC to control machine on/off times from multiple schedules written by the Plant Manager according to date,shift schedules,and holidays.(Basically, a text based electronic time clock with 10 or 12 time channels) The program does not require any other function other than an easy set of fields for the Plant Manager to fill in as required for scheduling. I have written similar things with Access, however a rather large crush of projects does not allow me the time to do much more than try to find something to plug into the system. They are currently using standard electronic time clocks, but their programming requirements are rather tedious for the plant manager to change on a regular basis. Does anyone know of an application available that is specifically written for time control?

I suggest using a time clock and its associated setting software... piece of cake...

Look at THEBEN time clocks.

I had actually checked out the Theben clocks before, however at the time only the 4 channel clocks were available in the U.S. It appears that the 16 channel units are now available. I have the Obliesk software,and it is very easy for a novice to program. I'll check with the rep, if they're in stock they will do the trick.Thanks for prodding my memory.
