PLC parameters

Measurement signal

Description

This control unit can transfer the probing signal. When this control unit is used, set the entry kenngr.measure.signal (P-AXIS-00516) to “PLC” or “PLC_TIMESTAMP” in the parameter list of the associated axis.

Data type

MC_CONTROL_BOOL_UNIT, see description Control unit

Characteristics

Edge evaluation: Use the edge parameterised in the axis parameter list in the entry kenngr.mess_neg_flanke (P-AXIS-00518) to accept the measured value.

Access

PLC reads request_r + state_r and writes command_w + enable_w

ST Path

gpAx[axis_idx]^.lr_mc_control.probing_signal

Commanded, requested and return values

Timestamp

Description

This control unit transfers the timestamp of a digital input terminal to the CNC via the HLI.

Data type

MC_CONTROL_SGN64_UNIT, see description of Control Unit

Access

PLC reads request_r + state_r and writes command_w + enable_w

ST Path

gpAx[axis_idx]^.lr_mc_control.timestamp

Commanded, requested and return values

ST Element

.command_w

.request_r

.state_r

Data type

LINT

ST Element

.enable_w

Special features

If the timestamp is used for the function “Measure with distributed clocks timestamp”, the probing_signal control unit must also be enabled.
