The PL1000E Communication Electronic Control Module (ECM) requires a "Parameter Configuration List" (PCL) file in order to execute parameter translations. The PCL file contains the definition of parameters on the source data link. The source data link can be either CDL or J1939, or both CDL and J1939. The PCL file contains the definition of how the parameters are to be translated onto the destination data link. The destination data link can be either Modbus "remote terminal unit" (RTU) or Modbus TCP. There are several processes and work products that are involved in the creation of a successful parameter translation configuration.Each process will be discussed in the following sections.Parameter Translation Files and Configuration Tools
Prior to a discussion of the procedure required to configure the PL1000E Communication ECM parameter translation, it is necessary to discuss a few work products used throughout the process.Parameter Translation Editor (PTE)
The PTE provides a user interface through which a user may design and architect the communications paths within his system. It is a software application available as a utility application within Cat ET and the Caterpillar Communications Toolkit.Parameter Translation Editor File (*.pte)
The PTE file contains a list of all parameters for a set of engine models that are available for translation. A PTE file is specific to parameters available on either CDL or J1939. Parameters that are listed within the PTE file may be selected and may be assigned a Modbus register through Cat ET or Caterpillar Communications Toolkit.Note: The registers are not pre-assigned registers in the PTE file.Parameter Configuration List (PCL) File (*.pcl)
The PCL file is the output of the PTE application. After a user has designed the desired ECM objects and associated translations in the PTE and chooses to save the file, a *.pcl file will be created. This file then contains all of the information about the parameter necessary for translation to Modbus.Create Parameter Translation Design
In the Cat ET application (version 2007B or later) or the Caterpillar Communications Toolkit (version 2007B or later), select the Parameter Translation Editor (PTE) from the "Utilities" menu.Note: Connection to the PL1000E is not necessary in order to use the PTE. The PTE software provides an interface for manual translation design. The PTE software also provides a PCL wizard for more rapid translation design for simpler systems. Each of the translation design methods are covered in the sections that follow. However, due to the importance of the interface, the interface will be discussed first. An explanation will be provided for the terms and objects that are used in the following sections.

File Operations
The "New" button clears the design interface and prepares the PTE for creation of a new Modbus Slave or Modbus Master file.The "Open" button initiates a standard windows "Open" dialog that can be used to load a previously created *.pcl into the design window.The "Save" button causes the PTE to commit
