Device-related Diagnostics – Digital ET 200C
Device-related diagnostics indicates which inputs or outputs are defective.
The header provides information on the length of the device-related diagnos-
tics.
Note
Device-related diagnostics is possible only with ET 200C stations which
have diagnostics capability.
ET 200C stations which do not have diagnostics capability have the value
”07
H
” in the header. The remaining bytes are reserved.
Station diagnostics of a digital ET 200C module has been requested by the
CPU and is stored in a data block DB 10, starting at data word DW 0. The
length of this device-related diagnostics data is 7 bytes.
The table below shows the position of the diagnostics data in the data block:
