Ex. 900 mA
• 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 or extension power supply modules.
