2.2 Detail Definition Setting Procedures
218IFD Detail Definition Dialog Box Details
2-10
Response Time
Enter the time (between 0 and 255) to wait for a response after sending a command using the MSG-SNDE
function. If a response is not returned, causing a timeout, the transmission will be retried as many times as set
in the Count of Retry Box.
The Count of Retry Box is disabled if 0 is set for the response time.
Note: Enter 0 for the response time if 0 is set for the Count of Retry Box and MEMOBUS is selected in the Pro-
tocol Type Column in the Connection Parameter Area.
Count of Retry
Enter the number of retries (0 to 255) to be attempted if a timeout is detected after sending a command with
the MSG-SNDE function. An error is returned for the MSG-SNDE function if a response is not returned
after the set number of retries.
Note: If the TCP is the only protocol set for the connect type, it is not necessary to set the number of retries. Enter 0.
Receive Buffer Selection
This parameter selects the buffer type when no-protocol communications is selected in the Protocol Type
Column.
Connection Number (CNO)
This column displays the connection numbers between 1 and 20.
With Ethernet communications, the connection number is used to identify remote stations.
The connection number corresponds to parameter 10 (Remote Connection Number) in the MSG-SNDE and
MSG-RCVE functions.
Local Port
Enter the local port number (between 256 and 65535) for each connection.
Do not enter a port number that is used for another connection, an engineering port number, or a diagnostics
port number. If 0 is entered for the local port number, the data for that connection number will be cleared and
“-----” will be displayed in the Local Port Column.
Note: The port number that is set for the engineering port, as well as 9998 and 10000, cannot be used if the connect
type is UDP.
Node IP Address
Enter the IP address of the remote station for each connection.
The data input range depends on the field of the remote IP address.
Field 1: 0 to 255 excluding 127
Field 2: 0 to 255
Field 3: 0 to 255
Field 4: 1 to 254
Enter 0 in all four fields to connect in Unpassive Open Mode.
Node Port
Enter the port number (0 or 256 to 65535) of the remote station for the connection.
Note: The combination of the node IP address and node port must not be in use for any other connection.
Connect Type
Select the transport layer protocol.
TCP: Communications is performed using TCP (Transmission Control Protocol).
UDP: Communications is performed using UDP (User Datagram Protocol).
