slave is connected and/or the fiber optic conductor
0
is interrupted or the slaves have no voltage.
A050
P956 Slave not ok
⎯⎯
In the case of serial I/O, the slaves required
according to the parameter settings are not
1
available (slave number an/or slave type).
A051
P956 Peer Bdrate
⎯⎯
In a peer-to-peer connection, the baud rate
selected is too high and/pr different
2
A052
P956 Peer PrD-L
⎯⎯
In a peer-to-peer connection, an excessive process
data length has been set (>5).
3
A053 P956 Peer Lng f.
⎯⎯
In a peer-to-peer connection, the process data
length of the sender and receiver do not agree
4
A065
P957 Auto Restart
⎯⎯
The line voltage is outside the tolerance band at
the moment (e.g. power outage). The firing pulses
0
are therefore inhibited. On power recovery,
however, the WEA option (P366) implements an
auto restart.

Match the baud rates of the SCB modules connected to
each ( P684 SST/SCB Baudrate)
Reduce the number of words
P686 SCom/SCB # PrDat .
