question on Kepware.

Hi All

Using Kepware OPC Server modbus ethernet driver.

If I have a WORD size tag in the controller
and i want to use a single bit it . e.g. TAG.0 in it
how do i reference it in Kepware server when i create tags in it.

Thank you.

You mean you want to adress a bit in a register ?
If you click the ? button next to the tag adress field in KEPServer, you get a listing of possible adressing formats.

Note that this only works if the controller supports mask write register (Function code 22)!!
