11.6.8 Checking the Consistency of the Network
Before you save, you should check the network configuration for consistency. The
following are reported, for example:
• Nodes that are not connected to a subnet
(exception: non-networked MPI nodes)
• Subnets that have only one node
• Inconsistent connections
Requirement
NetPro must be open.
Procedure
• Select the menu command Network > Check Consistency.
Result: A window "Outputs for Consistency Check" with hints for configuring
conflict-free networks and connections is displayed.
Inconsistent stations are color-coded in red.
Tip
You can select the window containing the results of the last consistency check at
any time using the menu command View > Errors and Warnings.
Alternative Procedure
1. Select the menu command Network > Save and Compile.
2. In the dialog box, select the option "Check and compile all."
The "Outputs for Consistency Check" Window
Messages and warnings are entered in this window if the consistency check found
incorrect project planning/configuration (can refer to the hardware configuration,
network or connection planning). A consistency check is carried out during the
following actions:
• Menu command Network > Check Consistency
• Menu command Network > Network > Check Cross-Project Consistency
• Menu command Network > Save and Compile
• Download to PLC (consistency check for the stations or connections to which
downloading is to be carried out)
