AutomationDirect's Do-More PLC
Do-more PLC supports Ethernet I/O directly from the Ethernet port on the CPU. Connected racks and drives are auto-discovered, and all connected Ethernet I/O points use native addressing. Users can independently adjust the poll rate for each I/O rack (slave). Ethernet slaves can be configured as "critical" I/O, so the CPU will drop out of run mode if that I/O rack or GS drive disconnects for some reason. Diagnostic functions are included.
