Error Codes and Countermeasures
Code number
NV3W PTs except
NV3W
ER10 ER0010
ER12 ER0012
ER4* ER004*
Other error codes
OMRON SYSMAC C/CV-series PLCs
NV3W error codes are displayed as "ER" followed by the two-digit code.
NV3W-V1, NV4W and NV3Q error codes are displayed as "ER00" followed by
the two-digit error code.
The notation for the NV3W is used in the following table. When using other
model "00" will be displayed after "ER."

possible (The PLC received
a command that cannot be
executed because the CPU
Unit is in RUN mode.)
ER10 Data error
ER12 Overrun error
Description
Data error An error occurred in the data dur-
ing communications. Check the
communications parameter set-
tings for errors.
Overrun error The PT cannot receive the data.
The PT detected an error (over-
run) in the communications data.
If this error recurs frequently,
check for noise or for errors in the
PLC or PT.
Header error ("*" 1. A command with a header that
is not recognized was received
will be replaced
at the host in C/CV Mode. The
by a number
connected PLC may be a SYS-
between 0 and
MAC C/CV-series PLC.
F.)
2. The corresponding address
type does not exist in the PLC,
e.g., the LR Area was specified
when connected to a CP1E
PLC. Specify the correct ad-
dress type.
Wrong PLC A PLC from a manufacturer other
than OMRON may have been
model
connected. This may cause error
codes for irregular contents that
depend on the communications
contents of the specific PLC
manufacturer to be displayed.
Check to see if the communica-
tions driver in the PT is the cor-
rect one for the connected PLC.
Countermeasure
No response was received from the
PLC. The cable is disconnected, the
communications parameters do not
match, the power is not turned ON to
the PLC, there is too much noise, etc.
Check for these problems and then
cycle the power to the PT.
Change the CPU Unit to MONITOR
mode.
An error occurred in the data during
communications. Check the communi-
cations parameter settings for errors.
The PT cannot receive the data. The
PT detected an error (overrun) in the
communications data. If this error
recurs frequently, check for noise or
for errors in the PLC or PT.
