Hi @nvlong248,

Does it work with another type?

Hi @Limraj Depends on some registers, it can work with 4 byte integer or 8 byte integer. But it would be helpful if I can add single register as 2 byte integer. Regards, Long

Hi @nvlong248,

I looked into this issue however I could not reproduce your error. Below are screenshots of my Scada configuration on different versions:

version 2.6.18: image

version 2.7.7.3: image

What version of Scada-LTS application are you using ?

Could you send screenshot of returned values from Modbus while using Modbus data type 4 or 8 byte unsigned integer on the same configuration ?
