5 Diagnostic inputs
The FC750x has a variety of diagnostic variables available automatically. They describe the state of the card
and of the Sercos ring:
Fig. 11: Diagnostic inputs
ActualPhase
The current phase of the Sercos ring is displayed.
RequestedPhase
The phase currently being requested (e.g. by the PLC) is displayed. The card or driver is presently
attempting to activate this phase.
SystemState
Gives more precise information about the current phase:
0xE001 = Phase 0
0xE002 = Phase 1
0xE003 = Phase 2
0xE004 = Phase 3
0xE005 = Phase 4
0xE008 = Break
0xE011 = Phase switch 0 -> 1
0xE012 = Phase switch 1 -> 2
0xE013 = Phase switch 2 -> 3
0xE014 = Phase switch 3 -> 4
SystemError
Indicates the current error state:
0x0000 = No error
0x8005 = Drive addresses are incorrect
0x8006 = HS-timeout (service channel)
0x8007 = Double AT-failure
0x8009 = Optical fiber bus is interrupted
0xD002 = Break
0xD003 = Switch from 2->3 failure (S-0-0127)
0xD004 = Switch from 3->4 failure (S-0-0128)
0xF001 = Configuration error (actual/nominal channel)
0xF002 = Error in the time slot calculation
0xF003 = Incorrect phase setting by the NC
0xF004 = Internal error
0xF005 = Error lifecounter
