PL1000E Communication ECM Caterpillar

Operational Problems

Usage:

SR4B 1BN

Symptom Procedures

Problem - Unable to Browse to the PL1000E Home Page - Network Connection

Probable Cause

Using Cat ET, confirm the Internet Protocol configuration. Confirm these settings with the network administrator.

Confirm the PL1000E Communication ECM is properly connected to power, ground, and key switch inputs in the system.

If the ECM Internet Protocol configurations are configured properly, try using a DOS shell window to "ping" the ECM.
At the command prompt, type the following command and press the enter key. Where "xxx.yyy.zzz.aaa" is the IP address or domain name of the module.
- Ping "xxx.yyy.zzz.aaa".
If the ping command indicates successful communications to the ECM and are still unable to connect to the device using the browser, then check the browser settings. Confirm the ability to connect to other sites on the network. Contact the network administrator for help concerning the appropriate settings in order to connect a personal computer to the ECM that is on the network.

Confirm the network cable is not a "Cross-Over" cable. The cable used to connect the ECM to a network should be a standard "pass-through" or "patch" cable.

Problem - Unable to Browse to the PL1000E Home Page Direct - Cross Over Connection

Probable Cause

Use Cat ET in order to confirm the Internet Protocol configuration. Confirm that the IP settings are set appropriately for direct cross over connections. Refer to the System Operation Troubleshooting Testing and Adjusting, RENR8091, "Internet Protocol Configuration" section in order to help determine the appropriate settings.

Confirm that the cable being used is a cross over cable.

Confirm the PC settings. Refer to the "Configuring a Non-networked Windows-based PC to Access the PL1000E Communication Module" section. Any deviation from the required settings may prevent browser access to the PL1000E Communication ECM embedded web pages.

At the command prompt, type the following command and press the "enter" key. Where "xxx.yyy.zzz.aaa" is the IP address or domain name of the module.
- Ping "xxx.yyy.zzz.aaa"
If the ping command indicates successful communications to the ECM and are still unable to connect to the device using the browser, review the PC settings and contact the network administrator. Certain settings are sometimes controlled by automatic logon scripts for certain networks. These will need to be temporarily disabled for direct cross over connections.

Problem - Unable to Establish FTP Connection with the PL1000E Communication ECM

Probable Cause

Confirm the ability to browse the embedded web pages using a browser. If unable to browse the embedded web pages, refer to the "LAN Network Ethernet Connection" or the "Loading the PCL file Using FTP or DOS" sections of this manual.

Confirm proper log on to the FTP server. Refer to the "Loading the PCL file Using FTP or DOS" section of this manual to review the procedure to log in to FTP server.

Attempt to establish an FTP connection to the ECM using the DOS shell FTP feature that is covered in the, "DOS FTP Session with the PL1000E Communication ECM using a command Prompt" section of this manual. Some browsers and graphical FTP programs manage FTP connections differently. Some browsers and graphical FTP programs may not be compatible with the PL1000E. FTP using DOS will always be compatible with the PL1000E.

Problem - PCL file not moved from "New" folder to "Current" folder

Probable Cause

Using a standard web browser, connect to the PL1000E Communication ECM and browse to the ECM mapping page. On the ECM Mapping web page will be displayed any known errors or issues with the PCL file. There are several things that can prevent proper processing of the PCL file. The table below shows the potential errors that can be displayed there as well as the remedy to repair the problem.

Problem - No response to data requests from Modbus Master

Probable Cause

The PL1000E Communication ECM provides communication statistics for received and transmitted Modbus protocol messages as well as the physical layer statistics for received and transmitted bytes. If the "Physical Layer Bytes Received" is not incrementing, analyze and repair the harness. If the "Physical Layer Bytes Received" is incrementing but the "Protocol Layer Modbus Messages Received" are not incrementing, analyze and correct the Modbus message format. The ECM will not respond to an improperly formatted Modbus message. Refer to the Troubleshooting, RENR8091, "Diagnostic Capabilities" for the "Messaging Statistics Quick Reference Troubleshooting Guide".
