4.
Check if expansion to the extension power supply module is permitted.
• 5 V DC power supply
• 24 V DC power supply
The value obtained by this calculation (when the value is positive) indicates the remaining capacity of 24 V DC service power
supply, and the capacity can be used for external loads.
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.
In the case of DC power supply type
Calculate following the procedure below.
1.
Check the power supply capacity of the powered input/output module.

Page 42 Powered input/output module)
2.
Check the current consumption of the extension module.

Page 43 Intelligent Function Module)
3.
Calculate the total current consumption of each power supply.
