Modbus Parameter Translation and ECM Configuration Quick Start Guide
The checklist that is in this section provides information for implementing and for configuring Modbus parameter translations with the use of the PL1000E ECM. Each step or procedure in the checklist references the appropriate section(s) of this System Operation Troubleshooting Testing and Adjusting, RENR8091, "PL1000E Communication ECM" that explains the detail of the respective procedure.Gathering Information for PL1000E Commissioning
Preparation for Commissioning PL1000E
Identify the type of "Programmable Logic Controller" (PLC) that is being used.
Verify that the PLC supports the native Modbus, NOT Modbus+.
Verify that the PLC is a Modbus Master that is capable of requesting registers 40,001 through 42,000.
Identify the protocol that is required for the Modbus. (TCP, RS-232, RS-485 (4 wire), RS-485 (2 wire), and RS-422).
Verify the baud rate for the serial port.
Identify the Modbus slave address in the PL1000E that the "Master" will request the information from.
If applicable, locate the unused Modbus slave address for the internal housekeeping.
Verify that the PL1000E is connected to a network.
Identify the type of network addressing that is currently being used.Note: The address type will be either "Dynamic Host Configuration Protocol" (DHCP) or "Static" addressing.
Locate the "Static" address information.
Verify the "Internet Protocol" IP Address.
Verify the Subnet Address.
If applicable, depending on the network, verify the Gateway Address.Caterpillar Dealer Questions
Verify all of the Cat Data Link ECM addresses.Note: The ECM address depends on the type of engine that is being used. To locate the ECM address, log onto Cat ET. Initially, ECM addresses may be in hexadecimal format, and will need to be converted into decimal format for the Parameter Translation Editor.
Locate the data link that the information is on from each ECM and the starting registers.System Block Diagram

Ensure that each Caterpillar ECM is defined. Ensure that each ECM has the correct address.
Verify all Modbus ECMs, and that each Modbus ECM has the correct Modbus slave ID.Note: The PL1000E has two Modbus slave addresses. The Modbus slave address that is configured in the PCL file is the address the Modbus Master uses in order to retrieve engine information. The Modbus slave address that is configured in Cat ET, Caterpillar Communication Tool Kit, or through the web server, is for the PL1000E's internal statistics.
Define all of the translation lines from the Caterpillar ECMs to the Modbus ECMs.
Select the NEEDED parameters on each translation line.Note: The Modbus registers that are associated with each parameter are shown in the right hand column.Note: All of the parameters that are in the General Parameter Translation Editor (PTE) files may not be supported.
Ensure that each defined ECM has a unique "ECM ID".Note: Please review the parameter list report for scaling.
Save a ".CSV" file from each translation line. This will be given to the PLC integrator.
Save the PCL file to a computer.Items During Commissioning
Wire the PL1000E for use with the PLC. Refer to "Caterpillar Dealer Questions" for instructions about the required connections for the PLC.
