4.
Configure the Ethernet Module parameters as follows:
It has two parts 1. Register Usage and 2. Protocol Support
Register Usage:
i. IP Address: Enter the static IP Address for the Ethernet Module being configured.
Note: IP Addresses are entered as four numbers, each ranging from 0 to 255. These four
numbers are called octets and they are always separated by decimal points.
ii. Net Mask: Enter the Net Mask (sometimes called Subnet Mask) being used by all nodes on
the local network. Typical local networks use Class C IP Addresses, in which case the low
octet (rightmost number) is used to uniquely identify each node on the local network. In this
case, the default Net Mask value of 255.255.255.0 should be used.
iii.
Gateway: Enter the IP Address of a Gateway Server on the local network that allows for
communication outside of the local network. To prevent the Ethernet Module from
communicating outside the local network, set the Default Gateway IP Address to 0.0.0.0 (the
default setting).
iv. Status Register: Enter an OCS Register reference (such as %R100) to indicate which 16-bit
OCS register will have the Ethernet Status word written to it. Table 3.1 shows how this
register value is formatted and explains the meaning of each bit in the Status Word.

v. Version Register: Enter an OCS Register reference (such as %R101) to indicate which 16-
bit OCS register will have the Ethernet Firmware Version written to it. The value stored in the
Version Register is: (Ethernet Firmware Version * 100). For example, for Ethernet Firmware
Version 4.30, the Version register will contain 430.
For the Status and Version registers (if configured), the Direction settings are always Read
Only
vi.
Use CAN ID for last Octet: The Use CAN ID for last Octet checkbox does not affect Net
Mask, Gateway, Status or Version configuration. If the checkbox is checked then it behaves
as follows:
