No values ​​returned from driver
« on: November 11, 2019, 10:29:19 AM »

I am trying to receive data from an arduino with which I send the data via modbus with an ethernetShield card, and receive it with the ModbusTCPCom component, the information is sent through arduino with a delay () every 10,000 ms. Through Modbus Poll I receive the information correctly configuring the response TimeOut  every 15000 ms, but when connecting via advancedHMI and modbusTCPCom I cannot get the data correctly in the basicLabel, obtaining the error messages "no values ​​returned from driver" most of Sometimes, sometimes I receive something with the same configuration. I have tried to modify PollRateOverride of the driver and pollRate of the basicLabel without success, where is my problem? Thank you.

Try modifying the TimeOut property of the driver to see if it improves any.
