Issue:
What is FDR fault on LTMR Controllers?
Product Line:
IEC Contactors and Overload Relays
Environment:
TeSys T Motor Management Controller
Cause:
Communications
Resolution:
The TeSys T incorporates an FDR function. If you have an FDR server the ones and tens dials on the front of the TeSys T can be set to get it an identity to allow the FDR server to provide it's paramter file.
If these dials are set, but no FDR server exists to feed the TeSys T a file, or with no network cable connected to the network port, then you will see a "Network Port FDR Fault" when the device is powered on.
If there is no network to connect to the rotary switches should be set to disabled, if there is but no FDR exists setting the dials to stored will allow you to use the IP address you program in to the TeSys T. See below for more information on these rotary switches:
The settings of the rotary switches determine the source of the LTM R controller’s IP address parameters
and the FDR service activation, as follows:

The settings of the rotary switches determine the source of the LTM R controller’s IP address parameters
and the FDR service activation, as follows:
| Left Switch (TENS) | Right Switch (ONES) | Source of IP Parameters |
| 0 to 15 (1) | 0 to 9 (1) | DHCP server and FDR service |
| N/A(2) | BootP | BootP Server |
| N/A(2) | Stored | The rotary switch is not used to determine IP parameters. LTM R configured settings are used. If none, IP parameters are derived from the MAC address. Modbus service is disabled. |
| N/A(2) | Clear IP | Clears the stored IP settings. No IP addressing settings are assigned. The network port is disabled. |
| N/A(2) | Disabled | The LTMR controller is not available for network communication. The LTMR controller does not initiate any IP acquisition process (host register, DHCP...) or announcements of IP on the network. Network related errors do not occur. However, the LTMR controller stays active on at the Ethernet switch level allowing the daisy chain to function normally. |
| (1) The 2 switches yield a value from 000 to 159, which uniquely identifies the device to the DHCP server. In the above figure, this value is 084, which is the concatenation of the:
The individual values of each rotary switch - in this case 08 and 4 - are incorporated into the device name, as described below. (2) The left (Tens) rotary switch is not used. The right (Ones) rotary switch alone determines the source of IP parameters. | ||
