[ a ] Parameter Details
This section describes the parameters in detail. The parameter number corresponds to the word offset from the first
address of the parameter list.
For example, if the first address of the parameter list is MA00100, set the value in MW00110 to set PARAM10.
„ Processing Result (PARAM00)
This parameter outputs the result of processing to the upper byte. The lower byte is used for system analysis.
