Troubleshooting
"Slave string faulty"
Data transmission error
between a slave and the mas-
ter.
Data connecting cable
interrupted.
If the error continues to occur,
check the connecting cable
between all devices.
"Wrong number of slaves"
During the master timeout, the
master receives more or fewer
reading results from the slaves
than expected from the num-
ber of slaves that the master
has entered.
The parameterized number of
slaves does not match the ac-
tual number of slaves connect-
ed
Timeout for the master is too
short
The data connection between
the slaves has been interrupt-
ed.
Check the entered number of
slaves.
To do so, upload from the CLV
using the "CLV-Setup" pro-
gram, choose the D
