Setting multiple bits from one PV button?

JerryH · Feb 28, 2010

I've got a PV600 connected to three machines on DH+ and am collecting data from counters from each one to display. I would like to add a button to reset all counters in each machine. How can I tie one button to three different node addresses to set a bit in each one to trigger the counter reset logic.
I've tried adding an invisible button over a button hoping both would actuate upon pressing the one displayed (this works in other touch panels) but I get an 'Overlapping Control Objects Error'

Any ideas???

Standard PV or PV+?

Don't know how to tell but it is a 2711-T6C8L1 (Ser B, Rev D, FRN 4.43)

That's a Panelview Standard. An easy way to tell is the black bezel versus the gray bezel. The Panelview Plus has a gray bezel.

I don't think there's an easy way to do what you want with the PV standard. The only way I can think of would be to put a message in one PLC that sends the reset signal to the other two when it received a signal from the Panelview.

Yep, I was going to do it with a message bit unless someone knew a way around it in the Panelview.

thanks,

Which PLC/SLC do you have. Look up "Global Status Flags"
for a PLC5 and "Global Status Word" for a SLC. Much easier way for processors to communicate between DH+ ports.

I did say message bit but I would use a bit in a 'Global Status Word' as these are SLC504's.

If that is a question then the answer is yes. See PDF below for
instructions if you need it.

Nice idea. I always forget about the global status words.

Yes very useful and very efficient way to pass info.

For those who don't know they are called "Global Status Flags" in the PLC5 world.
