Hello:
I am trying to initiate a new thread here.
As I sated before I have a problem of communication with two instruments: Hanna HI98192 and Lab power supply (30V, 10 A) from KIPRIM
My intention is use Labview to collect conductivity values in the conductimeter, and collect volyage and current from the power supply.
First of all I connect the instruments and check in the device manager if they are present. I do see them without problem.
I have to say that I have software from both instruments, but I want to use Labview to collect data
I have used NI MAX to check communication and I have ended for both instruments having an error that seems due to attributes: VI_ATTR_ASLR_CONNECTED: Invalid property value that generates a read error.
I am including seven images from NI MAX where you can see that I can identify instrument in a serial port, identify serial connection proiperties ( baud rate, stop bit, etc)
When I try write I do not have error, but I do not see any effect in the instruments, but if I use query or read, there is an error that you can see in images 6 and 7. I use *IDN\n as command.
I also will include commands for the conductimeter from a PC. I include the front panel functions and the commands from the PC I believe are for pressing the front buttons and some commands that request for conductimeter readings that are supposed to return time, temperature and conductivity
First of all I connect instruments using USB ports and I can see them in the Device manager ( Windows 11)
Then I run NI MAX to check connectivity. I can see the devices as serial connected as ell as the serial connection properties, both devices do not use flow control but both show the problem with attributes
