Parameters
Parameter list
Dependency: Refer to: r9795
Refer to: F30611
Note: The list for crosswise data comparison is described in fault F30611.
r9898 SI actual checksum SI parameters (motor module) / SI act_checksum MM
VECTOR Can be changed: -
Data type: Unsigned32
P-Group: Safety Integrated
Min
-
Description: Displays the checksum for the checked Safety Integrated parameters on the motor module (actual checksum).
Dependency: Refer to: r9798, p9899
p9899 SI reference checksum SI parameters (motor module) / SI set_checksum MM
VECTOR Can be changed: C2
Data type: Unsigned32
P-Group: Safety Integrated
Min
0000 hex
Description: Sets the checksum for the checked Safety Integrated parameters on the motor module (reference checksum).
Dependency: Refer to: p9799, r9898
p9904 Topology comparison, acknowledge differences / Topo_compare ackn
CU Can be changed: C1
Data type: Unsigned32
P-Group: Topology
Min
0000 hex
Description: If, when comparing the actual topology and target topology, only error has occurred, that can be acknowledged,
then using this parameter, a new comparison can be started - acknowledging the error in the target topology.
Differences that can be acknowledged:
- topology comparison, component shifted
- topology comparison, serial number of a component has been detected to be different (byte 3 = 1)
- topology comparison shows one component that is connected differently
The following parameter values are available:
p9904 = 1 --> the procedure is started.
p9904 = 0 after starting --> the procedure has been successfully completed.
p9904 = 1 after starting --> the procedure has not been successfully completed.
The possible causes for an unsuccessful procedure are located in bytes 4, 3, 2.
Byte 2:
Number of structural differences.
Byte 3:
Number of differences that can be acknowledged (p9904).
Byte 4:
Number of differences. These differences can be resolved as follows:
- sets the topology comparison (p9906 or p9907/p9908).
- change over the actual topology.
The appropriate action should be selected corresponding to the message that is displayed/output.
Note: In order to permanently accept the acknowledgement of the fault that can be resolved, then it must be saved in a
non-volatile fashion (p0977).
