Description
LS129 is a small and intelligent communication UV digital probe. It is suitable for various measurement occasions that need to detect UV power and energy in real time. The digital probe has a standard RS485 communication interface and supports MODBUS communication protocol. Its detector and controller are separate which is easy to installation and can be directly connected to a computer, PLC and human-machine interfaceI for communication in order to realize real-time data acquisition and monitoring.

Communication Parameters
1. Station No
The LS129 smart digital probe supports the standard MODBUS protocol. The default communication address is “1”. You can modify the probe communication address through the “Human Machine Debugging Tool” or the communication protocol. The address setting range is 1-247.
2. Baud rate
The default baud rate of the UV digital probe is 9600bps. The baud rate can be modified through the “Human Machine Debugging Tool” or communication protocol.
3. Protocol
Supports the standard MODBUS protocol. You can read the measurement data, set the communication address and baud rate through the communication protocol. For detailed communication commands, please refer to “LS129 Digital Probe Communication Protocol”.
