Chapter 5 Configure the I/O Modules
If DHCP is not enabled, the module uses the IP address (along with other
TCP configurable parameters) stored in nonvolatile memory.
At power-up, the module reads the rotary switches to determine if they are set
to a valid number for the last octet of the IP address. If the settings are a valid
number, these conditions result:
• IP address = 192.168.1.xxx (where xxx represents the switch settings)
• Subnet mask = 255.255.255.0
• Gateway address = 192.168.1.1
• The module does not have an assigned host name, nor does it use any
Domain Name System.
If the network does not use 192.168.1.x, after you install and power up the
module, you can use the following tools to set the network IP address:
• Bootstrap Protocol/Dynamic Host Configuration Protocol
(BOOTP/DHCP) server
• RSLinx® Classic software
• Studio 5000 Logix Designer application
Apply two labels to the module to identify the IP address of the module.
For more information on how to configure the module with these tools, see the
EtherNet/IP Communication Modules in 5000 Series Systems User Manual,
publication ENET-UM004
.
ATTENTION: Set a suitable network IP addresses before connecting the
module to a network.
IMPORTANT 1732ES modules have plastic dust caps that cover the network IP switches.
Remove the dust caps to adjust the IP address switches.
The dust caps must be installed to maintain the ingress protection (IPxx)
rating marked on the 1732ES modules.
Torque the dust caps to 0.3 ± 0.03 N•m (2.5 ± 0.3 lb•in).
IMPORTANT Your module comes preconfigured with a gateway address of 192.168.1.1.
IMPORTANT The gateway address automatically changes to 0.0.0.0 if the address
switches are set to match the gateway address.
