oPlc is a 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.
