F01120 (A) Terminal initialization has failed
Drive object: All objects
Reaction: OFF1 (OFF2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: An internal software error has occurred when initializing the terminal functions on the CU3xx, the TB30 or the TM31.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON (power off/on) for all components.
- upgrade the firmware release.
- contact the Hotline.
- replace the Control Unit.
Reaction upon A: NONE
Acknowl. upon A: NONE
F01122 (A) Frequency at the measuring probe input too high
Drive object: All objects
Reaction: OFF1 (OFF2)
Acknowledge: IMMEDIATELY
Cause: The frequency of the pulses at the measuring probe input is too high.
Fault value (r0949, interpret decimal):
1: DI/DO 9 (X122.8)
2: DI/DO 10 (X122.10)
4: DI/DO 11 (X122.11)
8: DI/DO 13 (X132.8)
16: DI/DO 14 (X132.10)
32: DI/DO 15 (X132.11)
1001: DI/DO 9 (X122.8), initialization error
1002: DI/DO 10 (X122.10), initialization error
1004: DI/DO 11 (X122.11), initialization error
1008: DI/DO 13 (X132.8), initialization error
1016: DI/DO 14 (X132.10), initialization error
1032: DI/DO 15 (X132.11), initialization error
Remedy: Reduce the frequency of the pulses at the measuring probe input.
Reaction upon A: NONE
Acknowl. upon A: NONE
F01150 CU: Number of instances of a drive object type exceeded
Drive object: All objects
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The maximum permissible number of instances of a drive object type was exceeded.
Fault value (r0949, interpret decimal):
Byte 1: Drive object type (p0107).
Byte 2: Max. permissible number of instances for this drive object type.
Byte 3: Actual number of instances for this drive object type.
Remedy: - power-down the unit.
- suitably restrict the number of instances of a drive object type by reducing the number of inserted components.
- re-commission the unit.
F01205 CU: Time slice overflow
Drive object: All objects
Reaction: OFF2
Acknowledge: POWER ON
Cause: Insufficient processing time is available for the existing topology.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - reduce the number of drives.
- increase the sampling times.
