Chapter

Configuring the Interface Module for
Ethernet Communication
Using This Chapter
Before You Begin Before configuring channel 3A for Ethernet communication, be
sure to:
• know the Ethernet hardware address (see page 2-2)
• assign an IP address to the module
Because the PLC-5 Ethernet interface module uses the TCP/IP
protocol, each Ethernet hardware address on the network requires a
unique IP address.
The IP address is software-configurable using either the BOOTP
protocol or your programming software package. See the “Manually
Entering Module Configuration Information” section on page 3-2 or
the “Using BOOTP to Enter Configuration Information” section on
page 3-4.
Contact your network administrator or Network Solutions Inc. (the
InterNIC) for a unique IP address to assign to your Ethernet interface
module. You can reach the InterNIC by dialing (703) 742-4777 or by
email at [email protected].

If the interface module is connected to You must assign
an Ethernet PLC-5 processor two (2) IP addresses:
• one for the PLC-5 processor
• one for the interface module
an Enhanced PLC-5 processor one (1) IP address for the interface module
a ControlNet PLC-5 processor one (1) IP address for the interface module
You must assign a unique IP address for each
Ethernet hardware address.
