oPlc is a powerful program that turns your Mac into a reliable Programmable Logic Controller.
There are more than 80 functional objects available.
● thousands of universal Modbus Input and Output devices available to connect via IP…
● use oPlc at home to control electric, heating, ventilation, cooling, access security, etc…
● control your model train track or other hobby equipment…
● use oPlc for education; learn the basic functions of a logic controller…
● contains basic HVAC components…
● use oPlc on a dedicated Mac mini for professional purposes…
There are many different objects divided into the following groups:
● Common – marker, register, timer, counter, time schedule, setpoint
● I/O – ModBus read or write coil, input and holding register
● Logic – digital port (N)AND, (N)OR, EXOR, flipflop, switch, BCD converter
● Compare – greater-, equal-, less, high and low limiter
● Calculate – add, subtract, divide, multiply, data conversion
● Controller – on/off, off/on, segmentation, PWM, P-regulator
For communication with Modbus-RTU devices an ethernet to RS485 converter is needed.
