Modbus simulator raspberry pi
For this demo we will connect up the the the MyPi board to a second PC running Windows and a PLC simulator, we'll then show how to read/write RTU registers. At this point you should have the ISO-485 card installed and successfully installed the mbpoll program. BACnet Raspberry PI. CBMS Studio have released a software bundle which will convert the Raspberry PI into a programmable BACnet device. The AAC-PI can be configured as a gateway to bridge between Modbus and BACnet protocols. It is fully programmable via a graphical engineering tool and has support for BACnet Alarms, Schedules and Trendlogs.
Jan 13, 2017 · Hi I got this system air ventilation now and I would like to get it hooked up to the openhab. It uses modbus protocol, and to be honest I have never dealt with modbus before.
