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	Tried to close the network server connection (nNTCONNØ)
	ALREADY CLOSED	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	Connection error or timeout with server. When polling and
	NOW BEING CLOSED	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	Tried to open a network server connection (nNTCONN1)
	FIRST	when the connection was already open.
	ERROR, INVALID FILE TYPE, NUMBER	Tried to read the wrong Allen-Bradley PLC file type, there
	OR SIZE. SETTING NTMP COMMANDS	are not enough elements in the file, or the file doesn’t exist.
	TO 0 ELEMENTS. CHECK MAPPING.	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	Tried to enable Ethernet communication (NTFEN) on a
	OPTION CARD - SEE OPTEN	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	Tried to connect to an Ethernet server (nNTCONN1) before
	ENABLED BEFORE MAKING	you enabled Ethernet communication in the 6K with the
	CONNECTION - SEE NTFEN	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	Tried to assign the status of OPTO22 I/O to a VARSHO
BE ASSIGNED TO A VARSHO	variable.
NETWORK IP ADDRESS CANNOT BE	Tried to execute an NTIP command while the connection is
CHANGED WHILE CONNECTION IS	open.
OPEN, SEE NTCONN
NO NETWORK IP ADDRESS SPECIFIED	Tried to connect (nNTCONN1) to a server # that has not yet
FOR CONNECTION, SEE NTIP	been established with the NTIP command, or tried to
	connect to a server in an incompatible subnet.
NTFEN MUST BE 1 TO USE THIS	(Peer-to-peer connection only) Tried to execute an NTRATE
COMMAND	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.
