Channel diagnostics

Function
Channel-related diagnostics provides information about channel faults in modules.
Channel faults are mapped as channel diagnostics data in IO diagnostics data records.
The data record is read using the instruction "RDREC".
Structure of the diagnostics data records
The data records supported by the ET 200SP distributed I/O system are based on the
PROFINET IO standard - Application Layer Service Definition V2.2.
You can download the standard PROFIBUS user organization (http://www.profibus.com)
from the homepage of the PROFIBUS User Organization free of charge.
Structure of the manufacturer-specific diagnostics data records
The structure of the diagnostics data records is differentiated by the BlockVersion. The
following BlockVersion applies to the IM 155-6 PN ST interface modules:
