"Synchronize Service Hour Meters" for PL321
In order to perform the "Synchronize Service Hour Meters" function, select the "Service" menu, and "Synchronize Service Hour Meters" from the drop-down menu.The machine maintains a function that is called "Sync Clock". In a PL321 system, the Product Link clock can be the master or the slave. This criteria is automatically determined by the priority that is provided to each ECM when the machine is designed. In most cases, Product Link will not be the master ECM. If Product Link is not the master, the user must use the "Synchronize" button in order to synchronize the Product Link SMH to the master ECM SMH. Product Link could be the master ECM if the following scenarios occur:
No other ECM on the machine is SYNC clock capable/enabled.
No other ECM on the machine has a priority higher than Product Link.If Product Link is the master ECM, the user should select the "Set Master Hours" button. Once the master hours have been set, click the"Synchronize" button in order to synchronize any other sync-clock capable/enabled ECM. Refer to Illustration 1.Note: In order to change the SMH to a value lower than the current value, a factory password will be required.Note: In a PL321 system using sync-clock where Product Link is not the master ECM, the Product Link module will automatically sync to the master ECM hours if the difference is not greater than 50 hours. If the difference is greater than 50 hours, a diagnostic will be generated in Cat ET that indicates that a manual sync is required. In that instance, sync the hours (Service/Synchronize Service Meter Hours) unless the master ECM hours are incorrect.If Product Link is not the master ECM, and the master ECM hours are not correct, troubleshoot on machine side. Do not replace the Product Link module.

"PLM Commands" Menu for Cat ET
There are ten commands that can be completed by selecting "Service/PLM Commands" from the menu bar in Cat ET.Registration - This command automatically queues a registration message and an administration message. The registration message will queue up and wait for the next available satellite to complete the process. The parameters "Queued Registration Messages"and "Queued Administration Messages" in "Message Queue" will show a value of "1". When the registration message and administration messages has been successfully transmitted, the value will change back to "0". This registration process can take from 15 minutes to 1 hour. The time frame is dependent on the performance of the communications network.Note: Performing the registration process will activate the installed system. Complete the configuration process prior to performing the registration process.Note: In order to register Product Link, the Product Link antenna must have a clear view of the sky for detecting satellites. Therefore, if the machine is inside of a building or another structure that would prevent a clear view of the sky, the machine will need to be moved outside.
