Page 3: Chapter 1 Product Introduction
Chapter 1 Product Introduction 1.1 Product overview JXBS-3001-ZFS Total Solar Radiation Sensor (Transmitter) is a sensor that can measure total solar radiation with a spectral range of 0.3-3μm. If the sensing surface is facing downwards, it can measure reflected radiation, and a light-shielding ring can also measure scattering radiation. - Page 4 PLC can be programmed through the modbus protocol specified later to cooperate with the sensor. use simultaneously USB to 485 can be connected to the computer, use the sensor configuration tool provided by our company to configure and test.
- Page 5 (See Appendix). In theory, one bus can connect more than 16 485 sensors If you need to connect more 485 sensors, you can use a 485 repeater to expand Charge more 485 devices, connect the other end to the PLC with 485...
