Input Parameters

Unless otherwise specified in the function block's description, the input parameters are read with the rising edge of the Execute input.

The input parameters are:

The PLCopen function / function block input parameters are:

PLCopen Function Blocks with Execute

These FBs initiate execution on the rising edge of Execute.
Execution continues until completion independent of the Execute value (or values) following initiation.
Once execution is complete, the function block can be rearmed or reengaged by introducing another rising edge of Execute.

Dual-Core limitation: Consecutive calls to the function block with repeating Execute values in the same cycle return an error code 76.

Function Block	Description
MC_AbortTrigger MC_SetPosition - Deprecated MC_SyncSlaves MC_TouchProbe	A positive transition of this input causes this function block to execute.
MC_CamIn MC_CamOut MC_GearIn MC_GearInPos MC_GearOut MC_Halt MC_MoveAbsolute MC_MoveAdditive MC_MoveRelative MC_MoveSuperimp MC_MoveVelocity	A positive transition of this input requests to queue the move.
MC_CamTblSelect	A positive transition of this input reads and initializes the specified profile.
MC_Phasing	A positive transition of this input requests to queue the phase shift move.
MC_Reference	A positive transition of this input requests to queue the reference move and arm the reference trigger events.
MC_Stop	A positive transition of this input initiates a stop move. While this input is held high, no other move can be queued for this axis.
MC_WriteBoolPar MC_WriteParam	A positive transition of this input writes the specified parameter.

These FBs continuously execute every PLC cycle, as long as the Enable remains high.

Function Block	Description
MC_Power	If this input is high and the drive is currently disabled, this function block requests to close the servo loop and enable the drive. If this input is low and the drive is currently enabled, this function block requests to open the servo loop and disable the drive.
MC_ReadActPos
MC_ReadActVel	When this input is high, the axis's actual velocity is returned.
MC_ReadAxisErr	When this input is high, the axis's error status is returned.
MC_ReadBoolPar MC_ReadParam	When this input is high, the specified parameter is read.
MC_ReadStatus	When this input is high, the function block outputs is updated.
MC_SetOverride	When this input is high, the override factors is written.

This is similar to ENABLE on function blocks.
Functions are expected to complete in one cycle.
See Differences between Functions and Function Blocks.

Function	Description
MC_AddSuperAxis	When this input is high, the specified axis is added to the superimposed axis list of the receiving axis.
MC_CreatePLCAxis	When this input is high, a PLCopen axis is created.
MC_EStop	When this input is high, an E-stop is generated for the specified axis.
MC_InitAxis	When this input is high, the specified axis is initialized.
MC_RemSuperAxis	When this input is high, the specified axis is removed from the superimposed axis list for the specified receiving axis.
MC_ResetError	When this input is high, the specified axis's errors is reset.
