Channel diagnostics

Function
Channel diagnostics provides information about channel faults in modules.
Channel faults are mapped as channel diagnostic data in IO diagnostic data records.
The "RDREC" instruction is used to read the data record.
Structure of the diagnostic data records
The data records supported by the ET 200MP are based on the PROFINET IO standard -
Application Layer Service Definition V2.2.
If required, the standard is available for free download on the Internet
(http://www.profibus.com) at the PROFIBUS user organization home page.
Structure of the manufacturer-specific diagnostic data records
The structure of the diagnostic data records is differentiated by the BlockVersion. The
following BlockVersion applies to the IM 155-5 PN ST interface modules:
