Coordinated System Time (CST)
The CST box in the lower, left-hand column of the Module tab provides the
following information.
Refresh or Reset Module
Click Refresh to refresh the information or click Reset Module to reset the
module to its power-up state.
Applying Changes
If all of the following conditions exist when you click Apply or OK, the
information is automatically sent to the controller:
• you are online in Program, Remote Program, or Remote Run mode, and
• this controller is the owner controller, and
• you have changed the module's configuration in the software.
The controller tries to send the information to the module (if the module's
connection is not inhibited). If you do not click OK or Apply, your changes are
not sent to the controller.
Parameter Description
Timer Hardware Displays OK or faulted for the timer’s hardware.
Timer Sync’ed Displays yes if the module’s timer is coordinated with the master.
Display no if it is not. This indicates if a CST master is providing a time
reference to the module. Configure a controller to be the CST Time
Master using the Controller Properties tab.
IMPORTANT
Resetting the module breaks connections and restores output signals to
default conditions.
