Galil Ladder Interface Software converts Relay Ladder Logic programs into deterministic code for its compact RIO-471×0 PLC. Direct RIO programming using two-letter text instructions makes coding flexible, but 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 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 software includes standard mathematical and logical operators including:
‚â€¢ Equal, Not Equal, Less than, Greater than
‚â€¢ AND, OR (normally open or normally closed)
‚â€¢ Add, Subtract, Multiply, Divide, Increment, Decrement
‚â€¢ Shift or rotate accumulator left or right
The RIO-471×0 Intelligent PLC provides 32 digital I/O and 16 analog I/O in a low-cost, small 3.9 in. x 4.3 in. x 1.3 in. 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.
