Since the range of the analog output holding registers is 40001 to 49999, it implies that there cannot be more than 9999 registers. Web16 aug. 2024 · In terms of dimming, I just use the analog output of my UniPi and use this 0-10 volt output to steer led drivers with this as input (if your google for 0-10 volt led driver you’ll find a lot). Do make sure you use 0-10 volt, not 1-10 volt as that won’t turn off the led lights completely (you need to cut the 110 / 230 voltage to the driver in the 1-10v case).
WebModbus is a serial communication protocol developed by Modicon, published by Modicon® in 1979, for use with programmable logic controllers (PLC). In simple words, it is a method for transmitting information over serial lines between electronic devices. WebIndustrial Communication Toolbox™ supports the Modbus interface over TCP/IP or Serial RTU. You can use it to communicate with Modbus servers, such as controlling a PLC, communicating with a temperature controller, controlling a stepper motor, sending data to a DSP, reading bulk memory from a PAC controller, or monitoring temperature and …
