Our memory map can do both of those things. The guide for that is here:
For example, using PAC Manager, you can see how long it’s been powered up (and compare that to a previous value, or see if it’s below a certain threshold). And you can also use PAC Manger/mem map writes to reboot a PAC, as shown below:
However, for your application since you have access to the strategies, I’d recommend doing something a little less brute force than a reboot like that. How many charts to your strategies have?
Also, does your HMI support Modbus? Because if it does, you could access these memory map addresses via Modbus.
But I’d recommend adding logic to your Powerup that says: “do I need to reboot myself?” (a button from the HMI) and then if it does, you can gracefully shut down whatever charts, perhaps make a log entry somewhere, etc. Do you see what I mean here?
