Modbus TCP Polling Delay
#1
Hello All,

I have an installation where the SpaceLynk is used as Modbus TCP Master and polling data from 5 Modbus touch panels.
I have set the poll time to 1sec so that the delay when a user presses a button on the touch panel is minimal.
I am testing now with the latest firmware 2.7.0 and I see most of the times like there is a delay of 4-5sec before the object value changes value in the maping window.
Is there a known bug? Its only three coil registers that are polled by the touch panels and in general SL is not busy.
Both devices are on the same Vlan and wired connection. Ping <1ms.

How can I minimize the delay between the button press on the touch panel and object update which writes into the knx?

What is the Persistent Connection checkbox for in the settings tab of the TCP/IP modbus device?

Can this be a network issue?
