Diagnostic Data of the Digital Input Modules
as of Byte 2
The structure and contents of the different bytes of the diagnostic data for special
digital input modules are described below. The following general rule applies:
When an error occurs, the bit concerned is set to ”1”.
You will find a description of possible error causes and appropriate remedies in the
section called “Diagnostics of the Modules”.
