PL1000E configured as a Modbus Slave
Cat DataLink (CDL) and/or J1939 to Modbus Parameter Translation
CDL parameters are given register assignments for accessibility through the Modbus interface. The parameters reside in holding register range of 40,001 through 42,000. Register assignments for CDL parameters are assigned through the "Parameter Translation Editor" in Caterpillar Tool Kit or Caterpillar Electronic Tool (Cat ET).The PL1000E supports the parameter translations feature over the following ports:
RS-232
RS-422
RS-485, 2 wire ( 285-1138, 256-7512 v4 and later)
RS-485, 4 wire
TCPThe 258-4548 Electronic Control Module is an ECM with no software installed. After the PL1000E software is installed on the ECM, the part number becomes 256-7512 Communication Electronic Control Module (v3). The 256-7512 Communication Electronic Control Module (v3) can only be configured for RS-485 4 wire. The 256-7512 (v3) cannot be configured for RS-485 2 wire.The 285-1138 Electronic Control Module is an ECM with no software installed. After the PL1000E software is installed on the ECM, the part number becomes 256-7512 Communication Electronic Control Module (v4). The 256-7512 Communication Electronic Control Module (v4) can be configured for RS-485 2 wire or 4 wire. The 256-7512 (v4) also supports multi-node communications.Cat DataLink (CDL) and J1939 to Modbus Parameter Translation - Dual Data Link Feature
The CDL and J1939 to Modbus Parameter Translation feature gathers information from both the CDL and the J1939 data links simultaneously.The dual data link feature will translate the CDL and J1939 data to the industry standard Modbus protocol interface. Cat ET version 2007B or later and PL1000E software release 315-0627 Communication Software Group or later are required in order to use this feature. Cat ET version 2007B will allow for both CDL and J1939 objects in the same "Parameter Translation Editor" window. Cat ET version 2007B will allow translation lines to and from a Modbus ECM. Custom Web Pages
PCL, Extensible Markup Language (XML), Extensible Stylesheet Language (XSL), and Cascading Style Sheet (CSS) files all reside on the PL1000E web server. All of these files work together in order to provide a customized view of data that is gathered by the PL1000E. In order for custom web pages to display information, the PCL file must be configured with a translation line to a web object. The custom web pages may include some or all of parameters on that translation line for monitoring and viewing in a web browser.PL1000E configured as a Limited Modbus Master
Cat DataLink (CDL) to Modbus Parameter Translation
CDL parameters are written to assigned registers. The register memory locations are on a "Modbus Slave" device which is connected to the PL1000E with the use of the serial port. The register memory locations are:
30,001 – 32,000
40,001 – 42,000The PCL file informs the PL1000E what information to translate. The PCL file informs the PL1000E which protocol to output these translations on.The PCL files are created and the PCL files are modified with the use of the "Parameter Translation Editor " (PTE). The PTE is found under the "Utilities" menu in "Caterpillar Communications Tool Kit" or Cat ET version 2007B
