Unique OMRON Error Codes
01 0810 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.
