In order to access the feedback signals, the function codes FC 05 (Force Single Coil) or FC 06 (Preset Single
Register) have to be used. The following tables give telegram examples for these function codes.

Warning message
Warning message
During self-check the electronic unit has
detected an error. The unit then performs
a reset and tries to enter the state fail-
safe. The indication can be cleared by
using the acyclic bit „Reset system test
error" in slot 1 index 240, or by using the
local reset in system>reset, or by a
power off on cycle. The kind of error
(refer to operating manual of i-matic) can
be read out by using the acyclic service
"system test error code" in slot 1 index
195 or the system entry under actual
value diagnosis on the local control
station. This indication is important for
safety related systems, if due to an error
the system needs to be brought to a safe
state.
