Read/Write Button
« on: February 08, 2018, 12:00:13 PM »
Hello

I have multiple buttons that need to run in some sort of write/read mode. For example, if a high level sensor is tripped I have the pump to be enabled through CCW. But I also want to be able to manually turn the pump on through my HMI. I'd like the HMI to show that the pump is enabled if the program enabled it because the high level sensor was tripped. But with the buttons I am using are write buttons and solely dictate whether the pumps would be on or off and do not allow the program to enable the pump. Is there a setting I am missing or another way to do this?

Thanks

Archie

A BasicButton has PLCAddressVisible and PLCAddressHighlight properties to control visibility or color change based on a PLC Boolean.
