Output of the checkback signals (axis attributes) of the IP247 positioning module (=> Section
2.7 "AxisAttributes").
D with S5115U:
The parameter contains the values: actual position value (BA 71 set) or the distance to go (BA73
set). If cyclic monitoring is switched off with mode 74, the value zero is output.
The output is either in BCD format (BCD = signal state"1") or binary (BCD = signal state "0") ac-
cording to the BCD parameter.
If parameters are assigned indirectly the following output parameters of FBI 64 are no longer up-
dated:
BTR – mode type
MFKT – M-functions
–
– display of the monitoring job
The updated values must then be taken from the axis data block.
In the axis data block (parameter DBNR) only the value selected with modes 71...73 is updated.
The other values are deleted (KHOOOO).
