AXIS_REF_SM3* AXIS_REF_SM3
When Execute turns to True and Busy is
False.
*Note: AXIS_REF_SM3(FB): Every function block contains this variable, which works as the starting program for function blocks.
 Function
 How to use MC_WriteBoolParameter to write the parameter value to the desired object with its parameter number in
EtherCAT Object Dictionary:
 Use SHL instruction to move the data length of the desired object to the left for 24 bits.
 Use SHL instruction to move the index of the desired object to the left for 8 bits.
The input ParameterNumber must contains the data length of the index and the subindex. Refer to the following
formula:
ParameterNumber: = - DWORD_TO_DINT(SHL(TO_DWORD(data length of object dictionary), 24) +
SHL(TO_DWORD(index of object dictionary), 8) + object sub-index);
 To write the value to the parameter, you’ll need to enter the parameter number of AXIS_REF_SM3(FB) into
ParameterNumber input.
 For operation example, refer to the example in MC_WriteParameter.
 Troubleshooting
 If an error occurs during the execution of the instruction, Error will change to True. You can refer to ErrorID (Error Code)
