Executive Upgrade Switch	Use to specify if the PLC has to be stopped
	to download new executive to PLC. The 2
	options are:
	lYes – PLC has to be stopped
	No – PLC does not have to be stopped

Keyswitch Override	Use to specify if the keyswitch on CHS 110
	modules is disabled (command register
	controls online/offline state of PLCs). The 2
	options are:
	Disabled – keyswitch controls online/
	loffline state
	Enabled – control register controls online/
	offline state
