Channel Diagnostics - Siemens IM 155-6 PN ST Manual

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
standard PROFINET IO - Application Layer Service Definition V2.3.
You can purchase the standard from the PROFIBUS User Organization on the Internet
(http://www.profibus.com).
