# Check the Application in SIMATIC Manager

Check the application in SIMATIC Manager as follows to make sure it runs properly:

1. Set a new byte value for User Data Cam0 in the monitoring variables. To do so, set the new value in the Modify value row, then click the Activate modify values icon.

   Note: This value is in hexadecimal format by default.

2. Give a rising edge to the Set User Data Cam0 bit. To do so, first set it to true, and then to false. Make sure to click the Activate modify values icon each time the value is modified.

   After this bit is set to true, the Set User Data Ack Cam0 bit also changes to true, indicating that the data from User Data Cam0 is sent out on the PROFINET network.

   After resetting the Set User Data Cam0 bit back to false, the Set User Data Ack Cam0 bit is also set to false.

3. After the above steps have been performed, the new value should appear on the web page configured in Updating the Job in the Adapter in SIMATEC.
