Limitation on Current Consumption

Power required for expansion adapters and extension modules is supplied from the CPU module. The number of
extension devices that can be connected must be determined from the capacity of the power supply.
Power supply check from the CPU module (current
consumption calculation)
Check if power can be supplied to extension devices with the power supply capacity of the CPU module.
