Hi all,
I've been lurking for some time now and have learned plenty. I hope to be able to share as much knowledge as I have gained from this site. I have an issue that I need help with. I apologize if this has already been discussed. I have done a search but couldn't find anything.
I am trying to synchronize the time from an S7 317F-2DP master to an S7 315-2DP slave via a CP 342-5 card (the CP card is in the 315 station). I have set up the 2nd DP channel in the 317F as a time synch. master at 1 min. intervals (the 1st DP channel is connected to a Profisafe network). I have set up the 315 as a time synch. slave under the "Diagnostics/Clock" tab (both "In the PLC" and "On MPI"). But so far nothing is working. I would have expected to find a "Pass on time-of-day frame to CPU" option in the HW config window for the CP card but there is no such option. Or do I need to use an SFC in my program to pass on these time frames?
Thanks in advance for any possible help.
