Modbus Driver 5.1.3.1 of SCADA 5.8.4

Hi,

In what scenario will this update affect?

For projects that are running on 5.8.2 and 5.8.3, should I update them to 5.8.4?

Hi,

Copied from the history https://rapidscada.net/doc/content/latest/en/version-history/communicator-drivers-history.html

KpModbus 5.1.3.1 (November 15, 2021)
- Fixed data packet format for multiple commands
  Warning: no backward compatibility for multiple commands having elements of 4 bytes or more

So it affects only multiple commands when you send more that 1 Modbus element.

> For projects that are running on 5.8.2 and 5.8.3, should I update them to 5.8.4?
In my opinion, if they work stable, you don’t need to update. New projects should be implemented on the latest Rapid SCADA.
