SpaceLogic Sensors Air Quality Sensors - Modbus

[jdsilvapereira]

Hi,

I have some SpaceLogic Sensors (Air Quality Sensors) and i'm reading using modbus/tcp. but the result value provided from address 1 (length 2) is 1,18287E-37 (32 float)  

 16 bits ->  545 | 257
 32 bits ->  35717377 

What is this value ? what is wrong ?

Hi @jdsilvapereira,

Can you also share what is the actual value shown in the display of the sensor (if it is available)?

Are you using Modbus scanner to check the reading?

Regards,

Ronald

Hi @jdsilvapereira,

Address 1.

If this is set as a input register then its temperature, if its set as a holding register then its the temperature setpoint.

Have you tried both swapped and unswapped?

BTW, what are you reading these on?

Hi All,

For slave 5 (2,3,4 and 5 are available, but the result is the same),

Hi @jdsilvapereira ,

On the first picture, what happens when the words are swapped?

Hi @jdsilvapereira , I've just found an SLP and plumbed it into EBO/AS-B

Settings should be 32 bit real,FC04, for the AS-B unswapped, may be swapped on other devices.

What does that mean?
