Hello list,

 

When using a ModBus Server (OneShotConnection = false) on one side and a ModBus Client on the other side (different program on a different computer)

I get increased CPU load on the ModBUs Server PC and I see that 

ModBusServerExecute(AThread: TIdPeerThread); 

Is interrupted massively.

 

If I, however, use any Freeware ModBUs Polling Software on the Client Side, there is no CPU increased load and the

 

ModBusServerExecute(AThread: TIdPeerThread);

Is interrupted with the same frequency as the polling frequency (as I would expect)

 

Why?

 

Regards
