problem diagnostics.
To monitor or force an I/O, find the I/O
point in the left panel of the screen.
Expand it as in Windows Explorer. Double

True or False, If you like, turn on the
‘Annunciator” and the sonalert will sound

“DIO” forcing and inputs and outputs can
be forced on or off.
The I/O point values can be useful along
with the States Screen information in
troubleshooting a problem.
