4.3 Configure the SMD23E2 or SMD24E2

The device will join the EtherNet/IP network as soon as the request is made to it. If the SMD23E2 or
SMD24E2 has a configuration stored in flash memory, it will be used to configure the unit on power up. You
can also configure the unit at anytime and store this new configuration to flash. Configuration is accom-
plished by writing a block of data to the device that is formatted according to the specifications in the
uration Mode Data
It is possible to store configuration data in the flash memory of the SMD23E2 or SMD24E2 and this configu-
ration will be used on power up to configure the device. However, writing the configuration data to the driver
on power up may simplify system maintenance if the device ever has to be swapped out.

4.4 Buffer I/O Data

Data to and from the SMD23E2 or SMD24E2 should be buffered once per scan using Synchronous Copy
instructions. This is to insure stable input data during the program scan and guarantee that complete command
data is delivered to the device. Ten word integer arrays can be used for this purpose.
These data tags should be buffered with Synchronous Copy File instructions to guarantee stable input data
during the program scan and guarantee that complete command data is delivered to the device.
