PIDAT
The data type of operation setting parameter OprSetParams is structure _sOPR_SET_PARAMS. The
specifications are as follows:
* MVLowLmt must be less than MVUpLmt.
The data type of initial setting parameter InitSetParams is structure _sINIT_SET_PARAMS. The specifi-
cations are as follows:
* RngLowLmt must be less than RngUpLmt.
