I/O Pair Connection Applications
The ET-2200 series modules can be used to create DI-to-DO pair connections via the Ethernet. Once
the configuration is complete, the modules can then poll the status of the local DI channels and then
use the Modbus/TCP protocol to continuously write to a remote DO device in the background. This
is useful when connecting Digital I/O devices that do not the mselves have Ethernet capability. The
following will describe how to correctly configure the I/O pair-connection function.
