that the module is stopped and no options can be found for starting module.

Use the following steps to add the block to the application:

• Open the Types Library Browser.
• Click on the Profibus library.

• Locate the 'PRM_MGT_M' block and add it to the application logic.

• Configure the parameters as described in the user manual with the exception of the MSTR_STS variable.
