Case 1： Busy and Active change to TRUE when Execute changes from FALSE to TRUE and one
period later, Done changes to TRUE and Datatype and Data show corresponding data. When
Done changes to TRUE, Busy and Active change to FALSE. When Execute changes from
TRUE to FALSE, Done changes from TRUE to FALSE and Datatype and Data retain original
values.
Case 2： Before DMC_ReadParameter_CANopen is executed, the input parameter value such as axis
No: 0 is illegal. When Execute changes from FALSE to TRUE, Error changes from FALSE to
TRUE, the values of Datatype and Data are cleared to 0 and ErrorID shows corresponding
error codes. As Execute changes from TRUE to FALSE, Error changes from TRUE to FALSE
and the content of ErrorID is cleared to 0.
Functions

DMC_ReadParameter_CANopen is used to read the parameter value of a slave. Users can specify the index
and subindex of the parameter to be read.
