Modbus Server on Raspberry Pi as Babelfish for UVR16x2

Our main data logger is the Control and Monitoring Interface of the freely programmable controller UVR16x2. There are two pieces of hardware you need for logging - the actual control unit and the logger connected to the controller via the CAN bus. This 'architecture' might be due to historical reasons, but I like the separation … Continue reading Modbus Server on Raspberry Pi as Babelfish for UVR16x2

Where Are the Files? [Winsol – UVR16x2]

We are using the freely programmable controller UVR16x2 (and its predecessor) UVR1611) ... .. and their Control and Monitoring Interface - CMI: The CMI is a data logger and runs a web server. It logs data … Continue reading Where Are the Files? [Winsol – UVR16x2]

Logging Fun with UVR16x2: Photovoltaic Generator – Modbus – CAN Bus

The Data Kraken wants to grow new tentacles. I am playing with the CMI - Control and Monitoring Interface - the logger / 'ethernet gateway' connected to our control units (UVR1611, UVR16x2) via CAN bus. The CMI has become a little Data Kraken itself: Inputs and outputs can be created for CAN bus and Modbus, … Continue reading Logging Fun with UVR16x2: Photovoltaic Generator – Modbus – CAN Bus
