# Bit number of process data element 'start measurement command' (P-AXIS-00700)

P-AXIS-00700 | Bit number of process data element 'start measurement command'
Description | This parameter defines which bit in the process data configured with P-AXIS-00699 is uxed to transfer the bit to start the measurement command to the drive. The last significant bit has number 0, the maximum value depends on the size of the process data used.

When the SERCOS control word is used for transmission of the 'start measurement command'' it, only bit numbers 6 and 7 can be used (real-time control bits 1 and 2).

Parameter | antr.sercos.probing_command_start.bit_nr
Data type | SGN16
Data range | -1 … MAX(SGN16)
Axis types | T, R, S
Dimension | T: ---- | R,S: ----
Default value | -1
Drive types | SERCOS
Remarks | If the bit number configured here is invalid, the error message P-ERR-110618 and the axis parameters P-AXIS-00118 (measuring axis) and P-AXIS-00098 (kasto_axis) are reset to prevent the execution of a measurement run or edge banding with incompletely configured probes.
