Hi!

I´m tryng to see values from a meter to tags in perspective but I can´t see all the decimals in the value, It seems that the values ​​can only be integers or 0.5 when the value is greater than 100.

For example in the meter I have 129.8 Volts and in the tag only appear 130.

Thanks for the help

Hi!

Try changing your OPC tag datatype to float.

Hello, thanks but didn´t work, I also tried changing every single parameter in the numeric section too.

It would be helpful if you supplied more information about your tag setup. Can you share your opcItemPath configuration? Did you read the Modbus addressing man page?
