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
● As of firmware version V4.2: The IM 155-5 PN 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.
● Firmware version lower than V4.2: The IM 155-5 PN HF interface module maps channel
faults by means of manufacturer-specific diagnostic data records.
The data records are based on the PROFINET IO standard - Application Layer Service
Definition V2.2.
You can purchase the standards from the PROFIBUS User Organization on the Internet
(http://www.profibus.com).
Coding of the extended channel diagnostics (as of firmware version V4.2)
With the IM 155-5 PN HF interface module, the following extended channel diagnostics are
