Shared Memory

The ET-2200 DIO series add a 512-byte shared memory which can be used as a tiny data concentrator
to store both the AIO and DIO data (256 Registers or 4096-bit shared single memory).
Shared memory used with the Pair-Connection function can effectively lower the host load. It can
also perform Bits/Registers data exchange, i.e., read data from the remote device and store them in
the memory or output signals from the memory to the remote device.
Note: Shared memory is only available for the firmware v2.4.0 and later. The older version is not supported.
