Faults and Alarms
List of Faults and Alarms
A50517 FBLOCKS: Int. meas. active
Reaction: NONE
Acknowledge: NONE
Cause: A Siemens internal measurement has been activated.
Remedy: Carry out a POWER ON (power off/on) for the Control Unit involved.
F50518 FBLOCKS: Sampling time of free run-time group differs at download
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: In the STARTER/SCOUT project that was downloaded, the hardware sampling time of a free run-time group (1 <=
p20000[i] <= 256) was set to a value that was either too low or too high.
The sampling time must be between 1 ms and the value r20003 - r20002.
If the sampling time of the selected free run-time group is < 1 ms, the equivalent value of 1 ms is used.
If the value >= r20003, then the sampling time is set to the next higher or the same software sampling time >= r21003.
Fault value (r0949, decimal interpretation):
Number of the p20000 index of the run-time group where the sampling time is incorrectly set.
Number of the run-time group = fault value + 1
Note:
For SIMOTION D410, r20003 (unlike all the other Control Units) is automatically set the same as the PROFIBUS
sampling time.
Remedy: - correctly set the sampling time of the run-time group.
- if required, take all of the blocks from the run-time group.
Note:
Fault F50518 only detects an incorrectly parameterized run-time group. If, after correcting p20000[i] in the project,
this error occurs again at download, then the run-time group involved should be identified using the fault value
(r0949) and the sampling time correctly set.
