Maintenance Access
The Maintenance Template will access all memory locations supported by the PLC driver as defined in
this manual. When running online, you may change the PLC reference. You must enter the correct
mnemonics and numeric values and create a legal reference to change a PLC reference.
Note:
A double word reference (ID, QD, MD, or SMD) should not be entered as the default
reference in the Maintenance Template.
Note:
When a new reference is entered on an Operator Station, the Maintenance Template will
remain in a paused state until the Start Monitor control button or the Chng soft function key
is pressed. When the Start Monitor control button or the Chng soft function is pressed, the
Operator Station will parse the reference. (Parsing means checking the syntax and range of
the reference to ensure that is supported by the driver.)
Note:
A Maintenance Template cannot be used to monitor unsolicited references.
