In addition: Modbus data bit 8, stop bit 1
Special note: Address 252 is used for broadcasting addresses, as long as it is used for several future situations
(1) The situation where there is only one instrument on the entire bus
At this point, the communication address of the current instrument can be set
(2) Start or stop all instruments on the entire bus
If there are multiple instruments on the bus and the address (register 0) is set with a 252 address on the bus, it will cause all instruments on the bus to have the same address, and future communication will not be able to correctly identify a certain instrument, resulting in the failure of the entire system.
2. MODBUS commands supported by instruments
function code | role | illustrate |
03 | Read Holding Register (16 bit Register) | Read one or more holding registers |
06 | Write a single 16 bit register | Set the current value of a holding register |
16 | Write multiple 16 bit registers | Set one or more holding registers |
6、note
1. The product is equipped with a laser emitter inside, and unauthorized maintenance may cause operators to be accidentally exposed to laser radiation. It should be repaired by specialized personnel from the manufacturer;
2. Prohibit opening the product casing for use;
3. The product does not directly come into contact with the monitoring environment (such as those installed in the equipment chassis). In order to obtain accurate sampling and measurement results, please connect the air inlet to the external probe of the chassis, and the length of the connecting hose between the external probe should be controlled within 30cm;
4. The external probe of the chassis needs to have windproof, coarse filtering, and waterproof capabilities.
