Multi Connection Server Function
6.1 Multi Connection Server Function
Multiple devices can be connected to the same port by making connection settings in advance.
Using the multi connection server function, servers with specified port numbers of the
connectable number "n" can be configured by making the same server settings for continuous
"n" connections using the setting tool.
The number of settable multi connection servers are as follows; Max. 16 connections for one
group, and 16 groups of servers.
Note)
When continuous sixteen connections are set, transmitted data from sixteen clients may not
be received simultaneously although TCP connection is available.
The number of data the Ethernet unit can receive simultaneously is limited.
When using the EtherNet/IP communication, the maximum number of simultaneous
receivable data from clients is eight. When not using the EtherNet/IP communication, it is
sixteen.
When using another Ethernet communication function, the actual number may be less than
the above receivable number.
6.1.1 Setting Conditions and Operating Conditions
Note the following when using this function.
1. This function is available only when "Specify IPv4 or IPv6" is set to "IPv4 only" in the
Basic communications information under Built-in ET-LAN setting.
When specifying other option than "IPv4 only" and specifying the multi connection server,
a unit error (warning) occurs.
2. Both system and user connections can be set.
3. When specifying "TCP/IP" for Communication type, Open type (server/client) should be
set to "Server connection".
When "Client connection" is specified, a unit error occurs.
When specifying "Server connection (specific destination), select "Use IPv4" for
"Destination unit IP address" as well as "Specify IPv4 or IPv6" of Basic communications
information.
Using "Server connection (any destination)" is recommended.
4. This function can also be used when "UDP" is specified for Communication type
However, do not use the multi-frame communication of "MEWTOCOL7-COM" and
"MEWTOCOL-COM". When using them, the communication cannot be performed
properly.
5. OPEN/CLOSE instruction can be executed only when specifying the first connection of a
group.
