Table 4: Diagnostic data of the SD slave
Always the 2nd byte of an SD slave in the response
Depending on the status of bit 6 (warning) and bit 7 (error) in the
response byte of the corresponding SD slave, the diagnostic byte
includes the following data:
Response byte

0 1
1 0
1 1
Description
SD Interface centralized alarm, message 1 sec. delayed, invalid SD data
Reinitialisation of the SD chain required! Shut down operating voltage of the
gateway and SD Slaves. Possibly no SD slave connected!
SD chain structure has changed after Power On! If OK, push TEACH
Bit 6 SD short circuit Short-circuit in the SD interface wires. Switch off and eliminate error.
One or more SD slaves unavailable. Invalid data from the SD slaves.
If necessary, check SD installation.
