Galil Motion Control, an industry pioneer in motion control technology, offers their new Ladder Interface Software for converting Relay Ladder Logic programs into optimized, deterministic code for its compact RIO-471x0 programmable logic controller (PLC).
"We offer this new software because Ladder Logic is typically used by PLC programmers to graphically input I/O logic," said Lisa Wade, VP-Sales and Marketing. "While direct RIO programming using Galil's two-letter text instructions allows for flexible coding, it is often easier to determine the I/O logic visually with Ladder Logic."
The software has an easy-to-use graphical interface that provides object types for contacts, coils, control relays, boxes (including timers, counters and data manipulation) and analog I/O. It also features a command box for specifying any valid Galil two-letter command. The Ladder Interface Software generates an optimized RIO program from the specified objects in the logic diagram. It also automatically adds determinism to the RIO program.
Additionally, the Ladder Interface Software includes standard mathematical and logical operators including:
Equal, Not Equal, Less than, Greater than
AND, OR (normally open or normally closed)
Add, Subtract, Multiply, Divide, Increment, Decrement
Shift or rotate accumulator left or right

Galil's RIO-471x0 Intelligent PLC provides 32 digital I/O and 16 analog I/O in a low-cost, small 3.9" x 4.3" x 1.3" package. An on-board RISC processor allows for quick I/O handling. Other features include Power-over-Ethernet, program memory with multitasking, process control PID loops, timers, counters, Ethernet10/100Base-T and RS232. Multiple RIO units can be networked for handling an unlimited number of I/O. The RIO provides a web-interface and email capability.
Available for immediate delivery, the RIO-471x0 is just $295 in single quantity and the Ladder Interface Software is $195.
