If you run an output or sensor supply input directly to an input (“Read back
output” function), you must take the following into account:
If no load is connected,
–
the diagnostics for the output or sensor supply must be disconnected in
the COM ET 200 (see section 5.1.4) or
–
a resistor (2.4 k
W
) must be connected to ground at the input for
wire-break recognition.

Output Returned to Input without Load
If a load is connected, a wire break is only recognized on the connection
to the load. The output

input connection can not be monitored for
wire-break.
