BMEP58•040 IP Address
In the absence of a valid application, a CPU with Ethernet I/O scanner service uses the IP address that is based on the MAC address printed on the front of the module. You can configure the IP address in Control Expert as detailed in the Modicon M580 Remote I/O Modules Installation and Configuration Guide when you have downloaded an application.
BM•CRA312•0 IP Address
In the absence of an application, the BM•CRA312•0 X80 EIO adapter module unsuccessfully
requests an IP address from a CPU with Ethernet I/O scanner service. The adapter module
then derives an IP address from the MAC address
printed on the front of the module. The module continues in this cycle
because it does not have a valid configuration. This Not Configured
state is indicated by the LED display on
the front of the module. There are no exchanges with the CPU. Physical outputs of I/O modules in the RIO
drops are in the fallback state (output forced at 0).
