MC_SetCamOnlineChangeMode

The function block MC_SetCamOnlineChangeMode specifies the mode for write access to cam plate data.

Cam plates can be modified at runtime via the PLC (see MC_WriteMotionFunction, MC_WriteMotionFunctionPoint). The function block MC_SetCamOnlineChangeMode is used to specify when and how these changes take effect. The set mode affects all subsequent write operations. It is therefore not necessary to call the function block before each write access.

This function specifies the activation mode for modifications but does not affect a change or changeover of cam plates.

Inputs

VAR_INPUT
   Execute            : BOOL;
   ActivationMode     : MC_CamActivationMode;
   ActivationPosition : LREAL;
   MasterScalingMode  : MC_CamScalingMode;
   SlaveScalingMode   : MC_CamScalingMode;
   CamTableID         : MC_CAM_ID;
   Options            : ST_SetOnlineChangeModeOptions;
END_VAR

Name	Type	Description
Execute	BOOL	The command is executed with a rising edge at Execute input.
ActivationMode	MC_CamActivationMode	Defines when and how scaling takes place. (MC_CamActivationMode)
ActivationPosition	LREAL	Optional master position at which scaling is performed (depending on ActivationMode). If the ActivationMode MC_CAMACTIVATION_ATMASTERCAMPOS is used, the position refers to the unscaled cam plate. If the position in the application refers to the scaled cam plate, it can be divided by the MasterScaling before the function block is called.
MasterScalingMode	MC_CamScalingMode	Type of master scaling. (MC_CamScalingMode)
SlaveScalingMode	MC_CamScalingMode	Type of slave scaling. (MC_CamScalingMode)
CamTableID	MC_CAM_ID	Table ID.
Options	ST_SetOnlineChangeModeOptions	Data structure with additional options:
Options	ST_SetOnlineChangeModeOptions	SynchronousAccess	Writing takes place via synchronous access without a time delay. Should only be used for applications that are extremely time-critical.

Outputs

VAR_OUTPUT
   Done          : BOOL;
   Busy          : BOOL;
   Error         : BOOL;
   ErrorID       : UDINT;
END_VAR

Name	Type	Description
Done	BOOL	Becomes TRUE when the function has been successfully executed.
Busy	BOOL	The Busy output becomes TRUE when the command is started with Execute and remains TRUE as long as the command is processed. If Busy becomes FALSE again, the function block is ready for a new order. At the same time one of the outputs, Done or Error, is set.
Error	BOOL	Becomes TRUE, as soon as an error occurs.
ErrorID	UDINT	If the error output is set, this parameter supplies the error number.
