How to increase the number of retries for HART?

Is it possible increase the number of retries for HART communication in Ovation?

  • Hi Stefan - would you be able to provide some more details into your situation? Is this wireless HART or is this from the I/O cards? What underlying issue makes you want to increase the number of retries?

    It is wired HART, on an OVATION AI (Hart)Card, E type card:5X00106G02 ;P type card:5X00109G01A

    I have a device which does not always replay to the HART telegrams, and I need the master to retransmit 5 or 6 times to get reliable communication.

    At the moment it is not an option to replace the device.

    Thanks Stefan. I am curious about a few more things. Hopefully you are able to answer these:
    What is the device type and name?
    What is the firmware in the device?
    And do you know the firmware on the HART AI card?

    In some of the other HART masters I have used, the number of retries is just a simple setting. Is that also the case for Ovation?

    The problem is related to the device, that is confirmed by using other HART masters and HART modems.

    I just need to know if the issue can be resolved by changing a setting in Ovation.

    Researching this further for you, unfortunately, it appears you cannot change the number of retries within an Ovation setting right now.
