Product Link 121S/300 – System Overview



Illustration 1 g01325084

The Product Link PL121SR is a communications device that uses satellites in order to transmit information to the following list: Caterpillar, Caterpillar dealers and Caterpillar customers. The unit contains a Global Positioning System (GPS) satellite receiver and a low earth orbit communication satellite transceiver.

Note: The time periods that are referenced in this publication are dependent upon the performance of the communications network which may vary at times.

The Product Link PL321SR is compatible with the communication protocol that is used on the Cat Data Link. All logged events and diagnostic codes that are available to the Caterpillar Electronic Technician (Cat ET) on the Cat Data Link can be sent to the satellite. The Product Link is not compatible with the communication protocol that is used on the ATA data link for on-highway trucks.

The Product Link PL121SR provides the customer with the following information: location, SMH (Service Meter Hours) and Fence capabilities of communication and configuration.

The Product Link PL321SR system provides the customer with the capabilities of the PL121SR system as well as the capability of the Product Link PL300 Electronic Control Module (ECM). The Product Link PL321SR system enables the customer to communicate and to configure the following functions: diagnostic codes, events and other Cat Data Link information.

The system allows two-way communication between the machine and a remote user such as a Caterpillar dealer or a customer. At any time, a user can request updated information from a machine. Also, the system parameters for the Product Link module can be changed. The information goes from the machine to a satellite. Then, the information goes to the ground station. The receiving station transfers the data to Caterpillar. The information can then be sent to Caterpillar dealers and customers.

Scheduled Reporting

The PL121SR or the PL321SR system can be set up to report on a regular schedule to the Equipment Manager system. The schedule can be selected by using Caterpillar Electronic Technician (Cat ET) software for both of the Product Link systems. The schedule can be modified with EquipmentManager or Cat ET software.

Note: The PL321SR system consists of the PL121SR system plus the PL300 ECM.

Fences

Fences are a feature of the Product Link PL121SR and PL321SR systems. These Fences can be set up only through EquipmentManager. Fences can be carried out in three ways:

  • Inclusive Geo-Fence sets up a “virtual fence” around a work site. Once Inclusive Geo-Fence is activated, a report is generated if the machine leaves the work site area.

  • Exclusive Geo-Fence sets up a “virtual fence” around areas that the machine is not allowed to enter. A report is generated if a machine enters a restricted area.

  • Time Based Fence allows the owner of a machine to choose the time that a machine can be operated. A report is generated if the machine is operated outside of the time that is set for machine operation.

Note: When a fence is activated, Product Link will send an event message to EquipmentManager.

PL321 only – If the alarm is still active on consecutive days, EquipmentManager will display a new Product Watch Event. EquipmentManager will send the appropriate event reaction once with the daily standard message. EquipmentManager will send the appropriate event reaction the next time the alarm is activated.

PL121 only – EquipmentManager will not display an alarm on consecutive days (regardless of active status) unless the machine leaves the work site or the machine enters a restricted area again.
