5. IAI Protocol B/TCP
This protocol uses TCP packets embedded with the message format of IAI protocol B for serial
communication. The controller supports the slaves under this protocol, regardless of the connection
method (client or server). (The connected device always becomes the protocol master.)
5.1 Setup of Ethernet Environment
The X-SEL controller provides IP addresses and other network-definition areas in its I/O parameters
for control of the IAI protocol B/TCP operation.
To select the IAI protocol B/TCP function:
Set “I/O parameter No. 129: Network attribute 10, bits 4 to 7” to “1: Use TCP/IP message
communication.”
Then, set “I/O parameter No. 124: Network attribute 5, bits 0 to 3 (MANU mode) or bits 4 to 7 (AUTO
mode)” to “1: Client (Assign own port number automatically)” or “3: Server (Specify own port number).”
Set the necessary parameters according to the network environment before connecting to the network.
Establishing a connection without setting the parameters may disable normal communication to and
from other devices on the network.
