By setting the load command code as the command code (RWwn+2), setting the parameter
number as needed, and changing the command code execution request (RY (n+2) 1) to ON, the
data corresponding to the set load code is set to the loaded data (RWrn+3, RWrn+4).
Obtained 32-bit data pieces are divided into the upper 16 bits and lower 16 bits when they are
stored in remote registers.
All data is in hexadecimals. At the time, the command code execution completion (RX (n+2) 1) is
turned ON simultaneously.
Load the data set to the loaded data (RWrn+3, RWrn+4) while the command code execution
request (RN (n+2) 1) is ON. The data sets the following load command code and the data is
retained until the command code execution request (RY (n+2) 1) is changed to ON.
If a command code not included in specifications is set as a command code (RWwn+2), an error
code (□□1□) is set in the response code. If a parameter that cannot be used is loaded, an error
(□□2□) is set.
Change the command code execution request (RY (n+2) 1) to OFF after data loading is
completed.
