Note
Class 2 master
!
If the actual configuration is not known to the class 2 master, it can first read the slave
configuration using "Get_Cfg" and then send it to the slave to be checked. This service
program is especially useful for modular systems.
Response from slave
The slave responds to a configuration message with "E5H" (short acknowledge). If the slave detects
discrepancies as compared with the entries in the GSD file, it report the configuration errors later when it
receives a diagnostic request from the master. It is not ready for user data traffic in this case.
4.5.6.3 Diagnostics
Diagnostic data are high-priority data. The DP/3WN1, 3WS1 interface module generates external
diagnostics if the connection to the external device (3WN1/3WS1 circuit-breaker) is faulted.
The diagnostic information of a DP slave includes standard diagnostic information (6 bytes) and possibly
user-specific diagnostic information.
The diagnostic request message from the master is structured as follows:
SD LE LEr SD DA SA FC DSA
P

68H x x 68H 8x 8x x 60/3

The diagnostic response message from the interface is structured as follows:
