Power balance calculation when configuring with STEP 7
STEP 7 checks compliance with the power balance during the configuration.
Proceed as follows to evaluate the power balance calculation:
1.
Perform the configuration of the S7-1500/ET 200MP with all the required modules.
2.
In the network view, select the CPU/interface module or the system power supply.
3.
Open the "Properties" tab in the inspector window.
4.
Select the "System power supply" entry in the area navigation.
5.
Check the "Power segment overview" table, so see whether the power balance is
positive. If the power balance is negative, STEP 7 marks the underpowered modules in
red.
