Error Conditions
Error Messages The 6K will transmit error message to alert you of certain error conditions. Following are the
error messages related to Ethernet networking.
Error Response Possible Cause
CONNECTION COULD NOT BE CLOSED OR
ALREADY CLOSED
Tried to close the network server connection (nNTCONNØ)
when the connection was already closed.
CONNECTION COULD NOT BE OPENED Tried NTCONN1 and failed. Problem could be invalid IP
address or it refused a connection.
CONNECTION ERROR, CONNECTION IS
NOW BEING CLOSED
Connection error or timeout with server. When polling and
get timeout or message aborted. This condition also sets
Error Status bit #23 (see ER, TER, TERF).
CONNECTION IS NOT OPEN Tried a NTWRIT when connection is not open; or tried a
\TANI or \TANO or \TIN or \TOUT or \TIO when
connection is not open.
CONNECTION IS OPEN - MUST CLOSE
FIRST
Tried to open a network server connection (nNTCONN1)
when the connection was already open.
ERROR, INVALID FILE TYPE, NUMBER
OR SIZE. SETTING NTMP COMMANDS
TO 0 ELEMENTS. CHECK MAPPING.
Tried to read the wrong Allen-Bradley PLC file type, there
are not enough elements in the file, or the file doesn’t exist.
The 6K automatically stop polling all mapped binary and
integer variables (equivalent to executing the
NTMPRBi,i,0,i, NTMPWBi,i,0,i, NTMPRIi,i,0,i,
and NTMPWIi,i,0,i, commands).
ERROR, INVALID STRING The DVT camera sent an invalid string response.
ETHERNET CAN NOT BE USED WITH
OPTION CARD - SEE OPTEN
Tried to enable Ethernet communication (NTFEN) on a
Fieldbus version of the 6K (part number is 6Kn-PB for
PROFIBUS units, 6Kn-DN for DeviceNet units). You must
disable the internal option card with OPTENØ before
enabling Ethernet communication. The 6K cannot
communicate over a Fieldbus connection and Ethernet
connection simultaneously.
ETHERNET COMMUNICATION MUST BE
ENABLED BEFORE MAKING
CONNECTION - SEE NTFEN
Tried to connect to an Ethernet server (nNTCONN1) before
you enabled Ethernet communication in the 6K with the
NTFEN command.
INVALID CONNECTION NUMBER Tried to make an NTS assignment or comparison using an
invalid server number (e.g., VARB1 = 7NTS).
INVALID I/O POINT Tried to read or write an OPTO22 I/O point that is not
configured according to the NTIO command.
INVALID POINT TYPE OR NUMBER,
SEE NTIO
Tried to set or read an I/O point (with an \IN, \OUT, \ANI,
\ANO, \TANI, \TANO, \TIN, or \TOUT command), but that
I/O point was configured with the NTIO command to be
different I/O type.
INVALID SERVER TYPE Tried an OPTO22-related command (\TANI, \TANO, \TIN,
\TOUT, \TIO, \IN, \OUT, \ANI, \ANO, etc.) for a non-
OPTO22 connection.
NETWORK INPUTS AND OUTPUTS CANNOT
BE ASSIGNED TO A VARSHO
Tried to assign the status of OPTO22 I/O to a VARSHO
variable.
NETWORK IP ADDRESS CANNOT BE
CHANGED WHILE CONNECTION IS
OPEN, SEE NTCONN
Tried to execute an NTIP command while the connection is
open.
NO NETWORK IP ADDRESS SPECIFIED
FOR CONNECTION, SEE NTIP
Tried to connect (nNTCONN1) to a server # that has not yet
been established with the NTIP command, or tried to
connect to a server in an incompatible subnet.
NTFEN MUST BE 1 TO USE THIS
COMMAND
(Peer-to-peer connection only) Tried to execute an NTRATE
command while NTFEN is set to a value other than NTFEN1.
NTRATE MUST BE 0 TO CHANGE NTFEN (Peer-to-peer connection only) Tried to execute an NTFEN
command while NTRATE is set to a non-zero value.
