A default value is stored in input variables, output variables, and public variables by creating an MCFB
instance. Programming can be shortened by setting input variables only for variables required to be changed
from the default value.
Execution procedure
The following shows the procedure for executing the Enable-type MCFB (MC_Power) using a motion module dedicated class.
The procedure is the same as when executing the Execute-type MCFB. Before using the motion module dedicated class,
make sure to fully understand the MCFB specifications which correspond to each instruction class.
When executing an Enable-type MCFB
Set 'TRUE' for the input variable 'Enable' and then execute the FB. After that, wait for the output variable 'ReadyStatus' to
change to 'TRUE.'
Then, set 'FALSE' for the 'Enable' and wait for the 'ReadyStatus' to change to 'FALSE.'

/*Motion module preparation completed*/
sRet = CCPU_X_In_BitEx( 0, 0x0000, &usData);
if( (sRet != 0) || (sData == FALSE) ){
return;

/*Set I/O variables and input variables of a member variable*/

/*Set I/O variables and input variables to the motion module and execute the MCFB*/
sRet = mcPower.SetEnable(TRUE);
