Block Modbus Writes

Is there any way to control the modbus write commands? I'd like to write a whole block at once instead of sequentially. Each tag has a .Write method but it looks like the modicon driver does each write command immediately and doesn't automatically group them like with reads.

We have no control of the Driver. Downloading the latest driver will possibly fix any issues. Otherwise, for large applications, you will need to utilize "Poll Groups." Ofcourse, you may or may not have an effect on the situation especially if you use "always active" since the data can be available on other screens.
