SIGA-CT1 with EEProm trouble

[gmcorreia]

Hello friends,

I have a EST3 (CAB14) with 9 loops.

Loop 1 - SSDC (135 devices)
Loop 2 and 3 - SDDC (189 devices and 174 devices)
Loop 4 and 5 - SDDC (125 devices and 120 devices)
Loop 6 and 7 - SDDC (133 devices and 138 devices)
Loop 8 and 9 - SDDC (154 devices and 49 devices)

The problem occur on loop 3. Some SIGA-CT1 modules show this message in the SDU software:

Bit 07 (Bit 7 of Byte 3)
Error with EEProm Id, EEProm not initialized

Anybody knows what means ?
