Heartbeat pulse from NA5 HMI

[Zeev]

Hello all,

I'm looking for some kind of pulse signal from HMI that can tell me that HMI is up and ready, I understand there are none specifically for that.

I can write a function in PLC that sends information to HMI and waiting to receive some other info, my question is how to do it nicely from HMI side? some global script?

Thank you

The NA5 does have a heartbeat signal. _HMI_RunSignal is defined as "Run Signal", "The value changes appropriately every second while the HMI is operating."
