*2 These are the maximum points that can be handled in the CPU module. The number of points actually used differs depending on the
module used.
*3 The maximum point differs depending on the parameter setting (Multiple CPU Setting).
*4 These devices are used in SFC programs. For details on SFC programs, refer to the following.
