Modbus Client Alarms - INT as WORD(16-bits)

NETWORKING SOLUTIONS

Hi,

I would like to ask if it is possible to read values of the WORD type in Modbus TCP Client?
If I create the request shown in the image below, I can see that BIT values are displayed. In the alarm configuration I would need to set the individual bits to different SMS messages.
When I create an alarm with the same request, it only compares the first bit of the read value.

In my case, I can rearrange all the read data as bool variables and read them with the Read coils(1) function. I am asking for the case when this option will not be available.

Thank you in advance for the answer.

@Something_Legit Hello,

In Modbus requests, you can choose the ASCII data type , which represents the register data as text.

Regarding alarms, the comparison value depends on the selected data type. If you choose Boolean , the value will be compared against either 0 or 1 . Generally, types are mostly converted to decimal representation for value comparison.

Kind Regards,
