MC_WriteParameter function for Motion control

[carlosb...@gmail.com]

The issue is when we are  using the “ MC_WriteParameter” Function,

 

When we press on “Number” under “ParameterNumber” to know which number to use ,

 

we are confusing by the below list, if we need to write “SWLimitPos” under parameternumber what is the write number should we use in the Function block ?

 

What is the formula used to calculate the number?

Answer:

You can just use the name of the parameter from the list and connect it to the ParameterNumber input of the function block:

MC_WriteParameter(

                Execute:= ,

                ParameterNumber:= SWLimitPos,

                Value:= MyLimitPosValue,

                Axis:= );

 

Sometimes it is not so clear which parameter name has to be used. For that reason there is a comment behind the name to make sure which index offset will be read or written:

                SWLimitPos,      (* lreal *)            (* IndexOffset= 16#0001_000E *)

 

The comment corresponds to the NC parameter documentation:
