6.3.3 Channel diagnostics
Function
Channel diagnostics provides information about channel faults in modules.
Channel faults are mapped as channel diagnostics in IO diagnostic data records.
The "RDREC" instruction is used to read the data record.
Structure of the diagnostic data records
• The IM 155-5 MF HF interface module maps channel faults by means of extended channel
diagnostics.
The data records supported by the ET 200MP are based on the standard PROFINET IO -
Application Layer Service Definition V2.3.
You can purchase the standards from the PROFIBUS User Organization on the Internet
(http://www.profibus.com).
