Input range Unit Remarks
C C 123
Network
attribute 4
0H 0H~FFFFFFFFH
Bits 0 to 3: Ethernet TCP/IP message communication
Selection of whether or not to permit IP address 0.0.0.0 (a
specification to ignore the IP address of the connected device)
as the connection destination when the controller is used as a
server
0: Do not permit
1: Permit (This setting is not recommended.)
* Note: Number of clients that can be connected to one
server-port channel simultaneously = 1
A A 124
Network
attribute 5
0H 0H~FFFFFFFFH
Ethernet TCP/IP message communication attribute
Ethernet client/server type
0: Do not use
1: Client (Assign own port number automatically)
(2: Client (Specify own port number)

This setting is not recommended in view of the
associated device restrictions, such as a forced-error
detection if the port is opened for approximately 10
minutes in a condition where a close response cannot
be confirmed due to a power failure in the connected
device, etc.)
3: Server (Specify own port number)
* Note: Number of clients that can be connected to one
server-port channel simultaneously = 1
Bits 0 to 3: IAI protocol B/TCP (MANU mode)
* PC software connection is enabled in the client mode only.
Bits 4 to 7: IAI protocol B/TCP (AUTO mode)
* PC software connection is enabled in the client mode only.
Bits 8 to 11:
User-open channel 31
Bits 12 to 15: User-open channel 32
Bits 16 to 19: User-open channel 33
Bits 20 to 23: User-open channel 34
* IAI protocol B/TCP MANU/AUTO
The connection will be cut off briefly during switching between
the MANU and AUTO modes, if the parameter settings of “own
port number,” “client/server type,” “IP address of connection
destination” and “port number of connection destination” do not
fully correspond between the two modes.
