110 IOLAN DS1/TS2 User’s Guide, Version 3.4
UID End When Destination is set to Host and you have sequential Modbus Slave IP
addresses (for example, 10.10.10.1, 10.10.10.2, 10.10.10.3, etc.), you can
specify a UID range and the IOLAN will automatically increment the last digit
of the configured IP address. Therefore, you can specify a UID range of 1-100,
and the IOLAN will route Master Modbus messages to all Modbus Slaves with
IP addresses of 10.10.10.1 - 10.10.10.100.
Range: 1-247
Default: 0 (zero)
Type Specify the configuration of the Modbus Slaves on the network.
Data Options:
z Host—The IP address is used for the first UID specified in the range. The
last octet in the IPv4 address is then incriminated for subsequent UID’s in
that range. The
Host option is not applicable for IPv6 addresses.
z Gateway—The Modbus Master Gateway will use the same IP address
when connecting to all the remote Modbus slaves in the specified UID
range.
Default: Host
Start IP Address The IP address of the TCP/Ethernet Modbus Slave.
Field Format: IPv4 or IPv6 (IPv6 format not supported for Destination Host )
End IP Address Displays the ending IP address of the TCP/Ethernet Modbus Slaves, based on
the Start IP address and the UID range.
Protocol Specify the protocol that is used between the Modbus Master and Modbus
Slave(s).
Data Options: TCP or UDP
Default: TCP
UDP/TCP Port The destination port of the remote Modbus TCP Slave that the IOLAN will
connect to.
Range: 0-65535
Default: 502
