MAC Address – Assigned at manufacture time, this value is read only and will be required by a network administrator to properly set up the ECM on the network.
Host Name – If Dynamic Host Configuration Protocol (DHCP) is enabled, the host name must be programmed with a descriptive name of the PL1000E device or its function in the system. Consult the network administrator to determine the appropriate Host Name for the device.
IP Address – This field is only applicable if DHCP is not enabled. If DHCP is disabled, then a static IP address must be defined here. This is also used when connecting a PC directly to the ECM using a cross-over cable. See this System Operation Troubleshooting Testing and Adjusting, RENR8091-01, “Explorer Gateway Service Manual” for details on connecting to this device directly using a cross-over cable.
SubNet Mask – If connecting to a network, contact the network administrator for the appropriate configuration of the SubNet Mask. If DHCP is not enabled, this will be required for static IP addressing.
Default Gateway IP Address – If connecting to a network, contact the network administrator for the appropriate configuration of the Default Gateway IP Address. If DHCP is not enabled, this will be required for static IP addressing.
DHCP – Dynamic Host Configuration Protocol is a process by which a device on a network may automatically obtain its IP address from a network server when the device is powered on or when the device is reconnected to the network. This process enables the use of either the Host Name or assigned IP address in a standard web browser to view the device’s embedded web pages. Consult with the network administrator for proper configuration of the DHCP enable function.
DHCP Results – If DHCP is enabled and executed successfully, the DHCP results will display the assigned IP address, the assigned SubNet Mask, the assigned Gateway, the assigned Hostname, and the assigned Domain. If DHCP is enabled, then the information that is typed into the fields above the DHCP area is not in effect.
Modbus Configuration
|

|
|
|
|
| Illustration 6 | g01717148 |
There are four locations (1), (2), (3), and (4) on the PL1000E that can be configured to provide a physical port for Modbus communications. There are three locations (2), (3), and (4) that are for a serial port and one TCP port (1) .
Modbus registers are made available on these ports as specified by the ECM objects that are defined in the PCL file. Any location can serve any port. The numbers are for identification only. The locations provide the expected resource for the ECM objects that are specified in the PCL file.
All four Modbus locations may be configured at the same time on a single PL1000E module, but no two locations can be set for the same port at the same time.
The default data link address is 254. The default data link address is also referred to as the “Device ID” (5) and (6) for all Modbus locations, including Modbus TCP.
The “Device ID” (5) and (6) does not need to be changed unless the system integrator has a specific reason for changing the “Device ID”. All four Modbus locations may use the same “Device ID” because each must be on different physical ports. The address, (5) and (6), is only used to access the “Default Status Registers” of the PL1000E. The “Default Status Registers” contain performance statistics of the PL1000E.
The address, (5) and (6), is distinct from the address that is used for the “Device ID’s” that are used by the ECM objects that are defined in the PCL file. The address, (5) and (6), is distinct from the parameters that are being translated. A “Modbus Master” device or ECM uses the “Modbus Slave” addresses that are defined in the PCL file in order to access the parameters for the ECM objects that are defined in the PCL file.
TCP
The PL1000E supports Modbus TCP over its Ethernet port. Since this communication can only be executed over the Ethernet port, there is no port selection associated with this Modbus Configuration. The PL1000E Modbus Slave Address configured here is the Modbus Slave Address that should be used by the Modbus Master to access the Default Status Registers of the PL1000E.
Config 1 / Config 2 / Config 3
Address – The “Device ID” (5) and (6) on which the “Default Status Registers” are provided.
Port – The PL1000E physical port (7) on which this location will provide Modbus communications. For example: if the PCL file specifies an ECM with Modbus translations over RS-232 port 2, then one of the Modbus locations must have RS-232 port 2 selected (7) for use by the ECM in the PCL file.
Baud – The baud rate at which the Modbus communications should be processed for this Modbus location and port (8). This setting must match that of the Modbus Master and all other Modbus devices on this network.
2 wire or 4 wire – The mode configuration must be set for the RS-485.
Cat Data Link Configuration
PL1000E Module ID (MID)
The PL1000E Communication Module can be manually configured to occupy any one of three distinct source addresses on the Cat Data Link. This parameter indicates which of the three source addresses the PL1000E should utilize. When multiple PL1000E Communication Modules are connected to the same Cat Data Link network, each must each be configured with a unique source address.
Boost
The ECM has the capability to extend the physical harness length limitations of the Cat Data Link network from the standard of 30.5 m (100 ft.) to a maximum of 305 m (1000 ft.). Enabling the Boost function of the PL1000E will allow Cat Data Link harnessing to which this device is connected to be run a maximum of 305 m (1000 ft.). See Special Instructions, REHS2362 for more information related to harnessing and wiring requirements.
Note: CDL boost that is available for the PL1000E, 256-7512 Communications ECM (v3), that uses the 258-4548 ECM, is enabled through a configuration parameter in Cat ET or through the embedded web page.
Note: CDL boost that is available for the PL1000E, 256-7512 Communications ECM (v4) that uses the 285-1138 ECM is enabled by grounding pin 7. Cat ET and the web page will show a status parameter that informs the user if CDL boost is enabled, or disabled.
|
|
| NOTICE |
|---|
|
CDL Boost should be enabled only if the wiring lengths for the harnesses are 30.5 m (100 ft) or greater. If the wiring lengths for the harnesses are under 30.5 m (100 ft), then CDL Boost may cause failure. |

Reset
Reset Action
Occasionally, it will be necessary to cause the ECM to perform either a warm or cold boot sequence, such as when updating the PL1000E Configuration Parameters or installing new PCL files. This web page provides the ability to request the PL1000E to perform a warm boot function.
Note: The warm boot function feature is protected by the password. The password is discussed in this “Symptom Procedures” section of this document.
PL1000E Status Web Pages
These web pages display the same status information that is available in the status screens of the service tool and can be used for communication verification and troubleshooting.

PL1000E Summary Screen |
|
ECM Serial Number – Hardware serial number of the PL1000E Communication ECM. The “ECM Serial Number” can be used in order to verify which ECM web pages are being viewed when multiple PL1000E devices are integrated into the same network.
Personality Module Description – The text description of the PL1000E Communication ECM as it is identified in the service tool data base. This is the same description seen on the ECM Summary screen in the service tool.
Personality Module Part Number – The Caterpillar part number of the application flash file currently programmed into the PL1000E Communication ECM.
Personality Module Release Date – The month and the year (last two digits) of the application software flash file release.
ECM Part Number – The Caterpillar part number of the PL1000E Communication ECM.
ECM Lifetime Clock – In earlier versions of software this text was “Service Meter Hours”, but was later changed to “ECM Lifetime Clock”. The “ECM Lifetime Clock” is a more accurate name, as this hour counter represents the total amount of time that the ECM has had power applied. It is not the number of hours the engine or system to which it is connected has been operated.

ECM Mapping Screen |
|
The ECM Mapping screen displays a tabular overview of the ECMs that are programmed into the device for parameter translations as defined in the PCL file. The table is separated into two sections of three columns. The ECM#, Type, and Port in each section combine to describe an ECM in the translation. The group of three columns on the left represent the From ECM, and the group of three columns on the right represent the To ECM. This From and To relationship describe the ECMs and direction of data translation relative to the communication ports and protocols.
FROM
- ECM # – This is the ECM address defined in the PCL file for this ECM object that the PL1000E Communication ECM will use to request data from the ECM.
- Type – The ECM Type as defined in the parameter configuration list (PCL file).
- Port – The physical port of the PL1000E to which this ECM is connected.
TO
- ECM # – This is the ECM address to which data translations from the source ECM will be made available.
- Type – The ECM type to which the data translations for the source ECM will be made available.
- Port – The physical port of the PL1000E Communication ECM to which data translations from the source ECM will be made available.
