I have air pollution monitoring analyzers Thermo environmental and Teledyne T series. I want to connect and collect data through Modbus serial or TCP. Is there anyone use the code for these analyzer with Campbell CR3000 logger or CR1000
please i need help on that topic i tried to use modbus sites but i couldn't make the code
Thermo Analyzers 42i, 43I, 45I, 48 i, 49i and 146i
Teledyne T100, T200, T300, T400, T700

I need help too
Hello I have some tips for connect an analyzer Thermo
We have several analizer in line using the next code
SlowSequence
Scan (2,Sec,3,0)
Flag_CM= ComPortIsActive(com3)
If Flag_CM =true Then
SerialIn(Dat_so2,com3,100,&h2A,150)
SerialFlush(com3)
SplitStr(split_cad(1),Dat_so2," ",10,5)
EndIf
Flag_CM=0
NextScan
the Analyzer have to configuration like stream protocol
I'm also in the process of doing air pollution monitoring analysis and need help as well. Can someone help me? doodle baseball
In a master and slave configuration, the communication stream is controlled by the Modbus master.
For connecting Thermo and Teledyne analyzers to a Campbell CR3000/CR1000 via Modbus (serial or TCP), you’ll need the Modbus register maps for each analyzer-these define which registers hold the measurement data. Once you have that, you can use the CRBasic MBUS_READ or MBUS_WRITE commands in your logger program.
Many users share example code for Thermo 42i/49i analyzers, but Teledyne models are less common. Contact the manufacturer for the Modbus register documentation-they usually provide it upon request. Having the register addresses and data types is essential before coding the logger.
