No.
No.
⎯⎯
Bit No.
A049
P956
no Slave
⎯⎯
In the case of serial I/O (SCB1 with SCI1/2), no
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

A052
P956
Peer PrD-L
⎯⎯
In a peer-to-peer connection, an excessive process
data length has been set (>5).

Peer Lng f.
⎯⎯
In a peer-to-peer connection, the process data
length of the sender and receiver do not agree

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.

Check the slave.
Check the cable.
Check P660 SCI AnalogInConf
Match the baud rates of the SCB modules connected to
each ( P684 SST/SCB Baudrate)
Reduce the number of words
P686 SCom/SCB # PrDat .
Match the word lengths of the sender and receiver
P686 SCom/SCB # PrDat
Important
An auto restart may constitute a danger for persons and
property. Make sure you really want to have auto restart
(WEA).
If necessary, change P366 WEA .
