MC_CamTableSelect

MC_CamTableSelect 1:

With the function block MC_CamTableSelect, a table can be specified and loaded into the NC. The block creates a new table and simultaneously fills it with data provided by the PLC.

MC_CamTableSelect does not have to be used, if a table created with the TwinCAT cam plate editor is to be used. In this case, simple coupling with MC_CamIn is sufficient.

Inputs

VAR_INPUT
    Execute         : BOOL; 
    Periodic        : BOOL; 
    MasterAbsolute : BOOL; 
    SlaveAbsolute : BOOL; 
    CamTableID : MC_CAM_ID; 
END_VAR

Execute	The command is executed with a rising edge at input Execute.
Periodic	Periodic is TRUE if the cam plate is repeatedly cyclically.
MasterAbsolute	At the moment not in use.
SlaveAbsolute	At the moment not in use.
CamTableID	ID of the cam plate used for coupling

Outputs

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

Done	Becomes TRUE, if the cam plate was created successfully.
Busy	The Busy output becomes TRUE when the command is started with Execute and remains TRUE as long as the command is processed. When Busy becomes FALSE again, the function block is ready for a new command. At the same time one of the outputs, Done or Error, is set.
Error	Becomes TRUE, as soon as an error occurs.
ErrorID	If the error output is set, this parameter supplies the error number.

Inputs/outputs


VAR_IN_OUT
    Master : AXIS_REF;
    Slave : AXIS_REF;
    CamTable : MC_CAM_REF;
END_VAR

Master	Axis data structure of the master - currently not used.
Slave	Axis data structure of the slave - currently not used.
CamTable	The data structure of type MC_CAM_REF describes the data storage for the cam plate in the PLC

The axis data structure of type AXIS_REF addresses an axis uniquely within the system. Among other parameters it contains the current axis status, including position, velocity or error status.
