JULY 2010 Keylock Switch Control
3.6 KEYLOCK SWITCH CONTROL
If your GC unit has the keylock control
enabled, you will not be able to write changes
or new data to the GC Controller. The following
error dialog will display.
To see which Modbus registers are affected by
the keylock control, view the Communications
section of the PC Config Report via the Report
Viewer (see Appendix A for instructions and an
example).
When closed ('on'), the GC keylock switch
protects many of the GC Controller's
parameters from being changed using
MON2000.
Most of the dialog boxes in the Application’s
menu allows you to view data but does not
allow you to save changes when the keylock
switch is closed. Several items in the Reports
and Control menus are unavailable when the
keylock switch is closed. The Users dialog
cannot be downloaded to the GC Controller
when the keylock switch is closed. A GC
application cannot be downloaded to the GC
Controller when the keylock switch is closed.
Since most of the GC Controller's parameters
are protected by the keylock switch, it is easiest
to list the operations that are available when
the keylock switch is closed. The following
operations are available when the keylock
switch is closed:
The keylock switch affects
only online operations, i.e.
those that are performed while
connected to a GC Controller.
The keylock switch feature is
only available on controllers
with BOS version 1.6 and
later. The GC Controller
parameters protected by the
keylock switch may vary
slightly from version to
version.
