#1: The restriction that there must be an empty slot between the CPU and any high-voltage module means a maximum
of six PI/O modules can be mounted.
#2: When using 100 V AC or 100 V DC as the power supply voltage of the PI/O modules, an empty slot must be left
between the CPU module and the PI/O modules. This means that a maximum of six PI/O modules can be mounted.
When using a 24 V DC power supply for the PI/O modules, the maximum number of PI/O modules that can be
mounted is seven.
