Remarks (restrictions)
1) Change in external wiring: Wiring using the terminal
block Wiring using the connector, change in wire size
2) Change in a program: Change in the number of
occupied I/O points, I/O signal, and buffer memory
address
3) Change in performance specifications: Change in
counting speed (2-phase, 7kPPS/1-phase, 10kPPS 
200kPPS/100kPPS/10kPPS switch setting)
: Review of counting range
24-bit binary (0 to 16777215)  32-bit signed binary
(-2147483648 to 2147483647)
4) Change in functional specifications: No change
