TouchProbe_ILX

Functional Description

This function block configures and starts position capture.

The function block returns the axis position at the occurrence of a trigger event. The drive trigger parameters are provided by the device implementation.

Executing the function block MC_AbortTrigger while MC_TouchProbe is busy aborts the function for the referenced trigger input.

A new rising edge at the input Execute overwrites and restarts the active trigger function.

Description

Execute

BOOL

Value range: FALSE, TRUE.

Default value: FALSE.

A rising edge of the input Execute starts the function block. The function block continues execution and the output Busy is set to TRUE.

This function block can be restarted while it is executed. The target values are overwritten by the new values at the point in time the rising edge occurs.

SingleShot

BOOL

Value range: FALSE, TRUE.

Default value: TRUE.

Selects the trigger occurrence.

  • FALSE = Captures continuously

  • TRUE = Captures once

Outputs

Output

Data type

Description

Done

BOOL

Value range: FALSE, TRUE.

Default value: FALSE.

  • FALSE: Execution has not been started, or an error has been detected.

  • TRUE: Execution terminated without an error detected.

Busy

BOOL

Value range: FALSE, TRUE.

Default value: FALSE.

  • FALSE: Function block is not being executed.

  • TRUE: Function block is being executed.

CommandAborted

BOOL

Value range: FALSE, TRUE.

Default value: FALSE.

  • FALSE: Execution has not been aborted.

  • TRUE: Execution has been aborted by another function block.

Error

BOOL

Value range: FALSE, TRUE.

Default value: FALSE.

  • FALSE: Execution of the function block is running, no error has been detected.

  • TRUE: An error has been detected in the execution of the function block.

Valid

BOOL

Value range: FALSE, TRUE.

Default value: FALSE.

  • FALSE: Execution has not been started or an error has been detected. The values at the outputs are not valid.

  • TRUE: Execution has been completed without an error detected. The values at the outputs are valid and can be further processed.

ErrorID

WORD

Returns the value of a diagnostic code. Refer to Library Diagnostic Codes. If the value is 0 and if the output Error of this function block is set to TRUE, then the diagnostic code can be read with the output AxisErrorID of the function block MC_ReadAxisError.

RecordedPosition

DINT

Returns the value the axis position at the occurrence of a trigger event.

Value range: -2147483648...2147483647

Default value: 0

Captured motor position in user-defined units.

Description

Axis

Axis_Ref

–

Reference to the axis (instance) for which the function block is to be executed (corresponds to the name of the axis). The name of the axis must be defined in the EcoStruxure Machine Expert Devices tree.

TriggerInput

MC_Trigger_Ref

TouchProbeNumber

UINT

Selects the capture unit of the drive.

TriggerEdge

ET_TriggerEdge

Edge to trigger position capture.

  • 1 / RisingEdge: Rising edge.

  • 2 / FallingEdge: Falling edge.

  • 3 / BothEdges: Both rising edge and falling edge(1).

See also Vendor-Specific Data Type ET_TriggerEdge.

(1) Only with EtherNet/IP and Modbus TCP.

Notes

Use MC_AbortTrigger function block to abort TouchProbe_ILX function block execution.
