Identification- and Device-related Diagnostics – Analog ET 200C
The device-related diagnostics for an analog ET 200C module indicate which
faults are reported by the module. The header provides information on the
length of the device-related diagnostics.
Station diagnostics of analog ET 200C modules has been requested by the
CPU and is stored in a data block DB 10, starting at data word DW n.
The table below shows the position of the diagnostics data in the data block:
