Clock management on TP

maxifox

Can someone clarify whether Touch Panels sync own clocks with Netlinx controller? I mean do TP themselves ask for time&date from the controller?

I know about system 'CLOCK' command, - this is not what I am talking about; that is rather TP internal (firmware) time sync forcing, if any. Looking for both G3 and G4...

The NetLinx master generates a UPD time message periodically, and the panels automatically update when they see it. As long as they are connected, they will get their time from the master.

Thanks, DHawthorne. How about G3 panels?

FYI:
When you modify the time of a panel you are actually changing the time of the Master. Which in turn modify's all the connected panel's time. This is applicable for both G3 and G4 panels.

Well, G3's certainly can't respond to the UDP broadcast, since they aren't on the Ethernet, but that doesn't mean they don't get a similar command via Axlink. I could have sworn G3 panels, however, kept their own time independent of the master; I might be wrong, I never paid all that much attention to it. You can, though, send the "CLOCK" statement to them from the master periodically if not.

My understanding of the clock in G3 is as follows:
1) G3 panels have their own internal clocks which can run fast or slow even from each other
2) When and change is made to a G3 panel's clock or to the master it will update all panels connected via axlink including a 2way wireless panel (VPN-CPs)
3) The !i-timemanager works very well for keeping accurate time on all panels, however there was a problem....it think with previous versions of firmware, were you had to update the panels yourself with the master's internet syncd time

That fits with my experience; you can set he master's time with the G3, but setting the master's time does not propogate to the G3 unless you use the CLOCK send_command.
