 D: Destination device.
 If a command is not the pulse execution type, adds 1 to the content of device
D
during each scanning cycle.
 Generally use this command as a pulse execution type command (INCP).
 During 16-bit operation, 32,767 +1 rolls over to -32,768. During 32-bit operation,
2,147,483,647 +1 rolls over to -2,147,483,648.
 When X0 switches from OFF to ON, it automatically adds 1 to the content of D0.
