The document describes Galil's RIO, a compact and low-cost programmable logic controller (PLC) for handling analog and digital I/O over Ethernet. Key features include 32 digital I/O, 16 analog I/O, a RISC processor, and support for relay ladder logic programming through Galil's conversion software. The RIO can operate as a standalone controller or be integrated with other Galil controllers and I/O devices using Modbus communication protocols.

6. RIO can be used as a stand-alone I/O controller,
connected to other RIOs or PLCs, or connected
with Galil’s Ethernet motion controllers.
• RIO as Modbus Slave: Another RIO or Galil
controller can send and receive info from an
RIO
• RIO as Modbus Master: RIO can send
information to other I/O devices

8. • Galil provides a software tool that converts
a standard Relay Ladder Logic (RLL)
program into a Galil program
• Allows user to graphically enter a complex
I/O routine into the software, and have that
routine run deterministically on the RIO
• Supports functions such as contacts, coils,
boxes (timers, counters, operators, etc)
and analog I/O
