Cautions
1. Setting the number of refreshed points "n"
Set a multiple of 8 such as "K8 (H8), K16 (H10) 
… K256 (H100)". Any other numeric value causes an error.
2. Setting the head device number 
Make sure that the least significant digit number is "0" such as "X000, X010, X020 
…"or " Y000, Y010, Y020 …"
Program examples
1. When refreshing inputs
Only X010 to X017 (8 points in total) are refreshed.
2. When refreshing outputs
Y000 to Y007, Y010 to Y017 and Y020 to Y027 (24 points in total) are refreshed.
