3.2.3 IP Address from OCS Register
‰ Use CAN ID for last Octet
9 IP Address Direction (Read / Write)
In this mode, the Ethernet Module’s IP Address comes from an OCS register. The IP Address
Register parameter indicates which 32-bit OCS registers to read the IP Address from. The static
IP Address parameter is not used in this situation, except to set the Default IP Address in non-
volatile memory.
Note: Every time an I/O configuration is successfully downloaded to an OCS with an Ethernet
Module, the static IP Address, Net Mask and Default Gateway parameters are stored in
non-volatile memory. In the event of a future unsuccessful I/O configuration download, the
Ethernet Module will communicate using these 3 stored parameters. This is done in an
effort to minimize potential loss of communication, which would require direct on-site
intervention to correct.
