Modbus TCP - OptimizationOn

Hello everyone,

I am working on a project with a PFC200, and it will communicate via Modbus TCP with 37 server devices.

In the Modbus configuration, there is a setting called “OptimizationOn”. Does anyone know exactly what this setting does and what its purpose is?

Thank you in advance for your help.

I have not checked it, but I think it means it will join requests if possible. E.g. you defined to request coils 1, 3 and 6 only, then the controller will do this either by three single requests or by one request, requesting coils 1 to 6.
