The worldwide network of Caterpillar's computers is passing messages to the Equipment Manager (EM) software.
EM is configured properly and the software is functioning.The Product Link PL102C module should not be replaced without first verifying that the issues mentioned above have been investigated and if needed, resolved. Contact the Service System Support Center for aid in resolving these issues.Every 24 hours, in "Power Mode 1", four position reports and one SMU report are transmitted. Fewer messages are sent in power mode 2 and power mode 3. If there is no position report after moving the machine and the SMU report is received, the unit is likely to be configured correctly.
