4 SYSTEM CONFIGURATION
4.4 Limitation on Current Consumption
4.
Check if expansion to the extension power supply module is permitted.
• 5 V DC power supply
• 24 V DC power supply
If the calculation result is a negative value, the current consumption exceeds the power supply capacity of the CPU module.
Reconfigure the system, adding powered input/output module.
Power supply check from extension power supply module
(current consumption calculation)
If 5 V DC and 24 V DC power supply of the CPU module is insufficient and cannot be extended, add an extension power
supply module.
Check if power can be supplied to extension modules with the power supply capacity of the extension power supply module.
Calculate following the procedure below.
1.
Check the power supply capacity of the extension power supply module used.
