I'm trying to dig to the source of a minor "recoverable" system fault throwing a fault light on a machine that has been confusing my operator because there's no apparent fault inhibiting operations. Thus far I've traced the fault to a bit tied to a GSV (Get System Value) instruction that's pulling it's number from "ControllerDevice" (selected as the Class Name). The number given right now is 12640 and this triggered fault is tied to the 9th bit in that number.
I've scoured the web for what this "ControllerDevice" number means and where in the PLC is generating it. Any ideas what ControllerDevice is pointing to? Is it hardware related? Where might this 12640 number be coming from?
Line 13, the bit being triggered. Ignore the "DS_TOGGLE_BIT". I just stuck that in there as a troubleshooting measure to see if this was the only thing behind the cabinet fault light and not something else.
