Hi all,
I have a problem with the Text Displays TD17 in our factory. We synchronise the Date & Time in the CPU with the TD17; we do this with the SFC SET_CPU_CLOCK. We write the data of the TD in DB's and we read this out of the DB to write the time in the CPU.
What's the problem? Wel, the clock doesn't hold her date & time right, I mean the TD17 doesn't hold it. We tried to put Back-up battery's in there, but, then we get messages on the TD when they should not be shown on the display (yes, really!!)
Therefore, I want to use the clock of the CPU instead of the TD17 clock. But, can I write date & Time of the CPU to the TD17 ?
It should be possible I think, else siemens is junk if that's impossible. How should I do it, write to interface area's (DB's) ?
In this way, we can synchronise the Clocks of all our cpu's with our PC on the profibus net.
Help would be gratefull,
thanks, and thanks again for those who want to give me an answer
