MEASURED VALUE BLOCK, READING 

The control module can transfer a considerable amount of test data. This test data delivers information on the 
operational condition of the system and/or sensor connected to it. In many cases the transferred test data 
supports troubleshooting and repair. The test data has been summarized into single display groups because all 
the information cannot be evaluated at the same time. The information can be selected via display group 
numbers.
