TP 170B color panel

walters · Mar 1, 2005

signed up this forum 2 days now and i allready my secons question:
is it possible to read out time from the TP into the PLC and then when the power is shut down the PLC maks sure that that time go's on and then when the power is back on the TP that the PLC signes the time back into the system of the TP so that the systems time of the TP allways is the right time

What you are asking is possible.

To syncronise the PLC time with the panel time you can use PLC job 14 (set time) and 15 (set date) to transfer the PLC date and time to the TP or PLC job 40 and 41 to transfer the TP date and time to the PLC.

I have never used these functions so I can't offer any more assistance than this.

If you are using an S7 with the TP, see the zip files posted by me in this post:
