LTMR: Ethernet TCP/IP

Introduction and Setup

This chapter describes how to upgrade/downgrade a TeSys T LTMR Ethernet TCP/IP firmware version.

It is applicable to TeSys T with LTMRxxExx references.

It explains how to prepare the LTMR and the PC, how to connect them and how to run the programmer.

Two physical links must be established between your PC and the LTMR.

One is a serial link from a USB port of the PC to the “LTME/HMI” port on the left side of the front face of the LTMR unit. It uses the TCSMCNAM3M002P cable.

The second link is from the Ethernet port of your PC to any of the Ethernet ports of the LTMR, using one Cat5 Ethernet cable. Route the cable to the outside of the enclosure so the update can be performed without exposure to energized equipment (doors closed and interlocked).

Prepare your PC — LTMR: Ethernet

Connection through USB to Serial

Download and install both “SoMove v2.6” or greater and “TeSys DTM Library v2.10.0” or greater.
Unzip and run the SoMove executable file.

NOTE: This will also install the Modbus Driver Suite for cable TCSMCNAM3M002P.
Unzip and run the TeSys DTM Library executable file.

NOTE: The file may run with no pop-up windows.
Identify the USB COM port used by the TCSMCNAM3M002P cable. To do so, connect the cable at both ends, click the Start menu on your PC and search for “Device Manager.” Open the Device Manager, then, click on Ports (Com & LPT) and read the number of the port associated with TSX C USB 485: In the example below, it is COM12.

Connection through Ethernet

You must configure a fixed IP address on your PC. In the first step, during the software upgrade of the LTMR, the LTMR will use its default IP address; then, in a second step, it will use the address 192.168.16.1.

For each of these two LTMR addresses, it is mandatory to define in your PC a compatible IP address. This means that the PC and TeSys T must be in the same Ethernet sub network.

To configure these fixed IP addresses in your PC:

Connect the Ethernet cable.
From the Start menu of your PC, search for the words “Network and Sharing,” then select “Network and Sharing Center.”
Click on Local Area Connection to which the LTMR is connected.
On the next window, click on “Properties.”
On the next window, select “Internet Protocol Version 4 (TCP/IPv4)” and click on “Properties.”
On the next window, select “Use the following IP address.” Enter 85.16.100.0 as the IP address and 255.0.0.0 as the subnet mask. Then, to define a second IP address for the PC, click on “Advanced.”
On the next window, click “Add.”
Now, enter the second IP address, 192.168.16.1 and click on “Add.” The subnet mask 255.255.255.0 is automatically selected and displays in the window.
Both IP addresses for the PC are now registered, and you can exit the previous IP addressing windows by pressing “OK.”

Using TeSys Programmer — LTMR: Ethernet

IMPORTANT: Changing the firmware version of the TeSys T through the programmer provides an automatic restore function for the product configurations. Before changing the firmware version, it is recommended to save a backup of the product configuration through the TeSys T Device Type Manager (DTM) using SoMove Software. The programmer can be used for both firmware upgrades and firmware downgrades. The following steps show how to upgrade the firmware from FW2.6 to FW2.7.

Open the TeSys Programmer Tool from one of the following locations:
1. Navigate to “C:\Program Files (x86)\Common Files\Schneider Electric Shared\TeSysDTMLibrary\TeSysT\TeSysProgrammer” and run “TeSysProgTool.exe.”
2. In SoMove:
  1. Click on the “Disconnect from Device” icon on the “Main” toolbar.
  2. Choose “Firmware Update” from “Device → Maintenance.”
A warning message is displayed, stating that the TeSys Programmer is to be used for TeSys T firmware change (upgrading to a new version or downgrading to a former version) and not for setting the configuration parameters of the TeSys T. Read the message and click "Proceed." If “Cancel” is selected, the programmer exits.

From the drop-down menu located underneath the TeSys T controller graphic, select the COM port associated with “TSX C USB 485.” In this example, it is COM 12. Click on the “Connect” button to connect to the TeSys T controller. Once connected, the “Connected Device Info” fields will populate.

Once the USB connection is established, the Programmer will import the default “IP Address” and the “Connected Device Info” from the TeSys T. Click the “Connect” button beside the IP Address to connect to the device through the Ethernet Port.
Once successfully connected through the Ethernet port, the button to the right of the IP address will read, “Disconnect” (giving you the option to now disconnect if desired).

In the “Firmware Package Selection” field, click the “Change Path” button, and navigate to the directory of unzipped TeSys T firmware files. Select the correct firmware package from the “Select Firmware” drop-down. Verify that the updated version has appeared in the Device FW Version field.

You are now ready to upgrade the TeSys T. To begin the firmware upgrade, click the “Update” button.

NOTE: Firmware upgrade can take up to ten minutes.

NOTICE
RISK OF FIRMWARE CORRUPTION Once the firmware upgrade has begun, adhere to the following until the programming process is complete: Do not close the TeSys Programmer until the process is complete. Do not interrupt power to the device. Do not disconnect the communication cable if programming is in progress. Failure to follow these instructions can result in equipment damage.

A pop-up window will appear, requesting you to power cycle the LTMR.

Once the “Total Progress” bar reaches 100%, a pop-up window will appear, indicating a successful LTMR firmware upgrade. Press “OK,” power-cycle the device again and wait 20 seconds. Then, click the “Connect” button.

After clicking the “Connect” button, the new firmware version should populate.
The firmware update is finished and you can exit the TeSys Programmer or continue using the tool.

NOTE: If you access your TeSys T through a LTMCU, depending on the firmware upgrade performed on TeSys T, you may have to update the language files of your TeSys T.
If this occurs, and the language files in the LTMCU are not updated, the LTMCU displays “Error in languages” when connected to TeSys T.
It is nevertheless possible to operate temporarily both the TeSys T and the LTMCU, but the new TeSys T configuration parameters introduced by the new TeSys T firmware version will not be accessible. The LTMCU languages must be updated to access the TeSys T configuration parameters introduced by the new TeSys T firmware version. To do so, use the LanDown tool and refer to the LTMCU User Manual.
LTMCU language file update may be necessary when LTMR is upgraded based on the following compatibility rules:
- LTMR firmware version 2.5 or 2.6
  - LTMCU language version must be 1.200 or higher.
- LTMR firmware version 2.7 or higher
  - LTMCU language version must be 1.300.
