Hi, everybody. There is an error:
811 FCP IO link communication error 12400001

What was done:
1. replaced optical cables
2. Replaced the FUB-DR3 unit
3. replaced the FUB-P4M4 unit
4. replaced the FUB-P4R2 unit
5. reinstalled the system
6.checked all power supplies.

Please help, okuma representatives claim that the FUB-DR3 unit is faulty, but it was replaced with a serviceable one.
What else can I check? or what actions to perform?

hi Vasily
If you have a CNC OSP U100L, then the error is deciphered as follows:
A transmission error has occurred in the I / O connection of the Fiber Channel Protocol (FCP) card
code WXYYZZZZ-12400001
W = always 1
X = 2 -> HSCC initialization error
YY (40) = Bit 6 -> double receive error
ZZZZ 0001 = Bit7-0-> slave station number where the error occurred (master station: $ 00) next $ 01 there is a problem.
Okuma's specialists pointed out you correctly. We need to check again.
