How to increase poll rate for Modbus TCP "Plz help" Thanks
« on: May 19, 2015, 06:42:10 PM »
Hi,

I am using Basic label to get value of address using Modbus TCP, But i really need to get value very quick like  5 Millsec " I suppose i want the polling rate of Modbus tcp to be 5ms". Can you tell me whats the default its using?  and how i can make it 5ms?  Really appreciate your help thanks.

Regards

5ms is quite fast. It depends if your device and network can turn around that fast. You can increase the update rate by lowering the PollRateOverride value in the properties of your ModbusTCPCom driver
