Error Response
Possible Cause
NTSELP ALREADY ENABLED ON THIS
TASK
NTSELP, which enables program selection via OPTO22
inputs, has already been enabled (if multitasking, it has
been enabled for this specific Task).
OPTION CARD CAN NOT BE USED WITH
ETHERNET - SEE NTFEN
Tried to enable the internal Fieldbus Option card for
PROFIBUS or DeviceNet communication (6Kn-PB and 6Kn-
DN products only) with the OPTEN1 command. You must
disable Ethernet communications with the NTFENØ
command before enabling the Option card. The 6K cannot
communicate over a Fieldbus connection and Ethernet
connection simultaneously.
VARB USED BY OPTION CARD
Tried to map a binary variable to read from or write to an
Allen-Bradley data file, but the variable is already used for
Fieldbus (PROFIBUS or DeviceNet) data transfer functions.
VARIABLE MAPPING CONFLICT, SEE
NTMPRB, NTMPRI, NTMPWI, NTMPWB
MAPPINGS
Tried to map the same 6K VARB or VARI variables for read
and write functions. Or tried to map the same 6K VARB or
VARI variables to another PLC.
Error Handling
The 6K has a Error Status register for logging certain error conditions. If you enable checking
for an error condition (see
ERROR
command), the 6K will branch to the designated error
program (see
ERRORP
command) when it detects the error condition. The Ethernet networking
related Error Status register bits are noted below.

How to Remedy the Error
23 Ethernet Client
Connection Error.
(Can’t connect.)
Gosub
Clear the error bit (ERROR.23-0), re-establish
the Ethernet connection (nNTCONN1), and
then issue ERROR.23-1.
24
Ethernet Client Polling Error.
(After connect and polling
device for data, polling
timeout occurred. Cause
could be disconnect, client
lost power, etc.)
Gosub
Clear the error bit (ERROR.24-0), re-establish
the Ethernet connection (nNTCONN1), and
then issue ERROR.24-1.
