Configuring the Encoder
Configuring the 842E-CM
Encoder IP Address This section offers guidance on configuring your Ethernet connection to
the 842E-CM encoder.
Ethernet Connection
Configuration, programming, and diagnosis of the encoder are
performed over the standard 10/100 Mbps Ethernet communication port
by using the Logix Designer application.
842E-CM Encoder Port Configuration
The IP address of the 842E-CM encoder is composed of four octets
separated by three dots to conform to the Class C Subnet structure. Each
octet can be configured with a number between 1 and 254.
There are two methods of changing the current IP address. An address
can be automatically assigned to the encoder (dynamic IP address) when
the encoder is connected to a DHCP (Dynamic Host Configuration
Protocol) enabled server, or you can manually assign a IP address to the
encoder (static IP address). Both methods of configuring the encoder’s IP
address are shown here.
Setting the IP Address The 842E-CM encoder is shipped with the network address switches set
to 999. You must assign the encoder an IP address using one of the two
methods outlined below.
Set the IP address of the 842E-CM encoder using either one of the
following methods:
1. Use the network address switches (see figure on page 26) on the
encoder to set the last octet of the IP address (192.168.1.xxx).
2. Use the network address switches to enable BootP / DHCP and use
a BootP utility or DHCP server to assign the IP address of the unit on
powerup.
