Error code returned from target:

New data could not be obtained 
from the CPU Unit when open-
ing connection. (The Unit will 
automatically retry, and attempt 
to open the connection again.)

This error may 
occur if the CPU 
Unit’s cycle time 
was long when 
opening the con-
nection, the speci-
fied EM bank was 
converted to file 
memory, or some 
problem in the 
PLC caused the 
PLC to stop.

If the cycle time 
was too long, the 
problem will be 
resolved automat-
ically. If the EM 
bank is set as file 
memory, change 
the storage loca-
tion for the tag 
data. If the PLC 
has stopped, 
identify and cor-
rect the error.

If the PLC system 
is stopped, iden-
tify the cause of 
the error from the 
CPU Unit error 
data.

The meaning of this 
error code is defined 
by each vendor, so it 
depends on the tar-
get’s specifications.
