A8A2 RO toggle warning The relay output is changing
states faster than
recommended, eg. if a fast
changing frequency signal is
connected to it. The relay
lifetime will be exceeded
shortly.
Replace the signal connected to the
relay output source with a less
frequently changing signal.
0001 Relay output 1 Select a different signal with parameter
10.24 RO1 source.
0002 Relay output 2 Select a different signal with parameter
10.27 RO2 source.
0003 Relay output 3 Select a different signal with parameter
10.30 RO3 source.
