How to get result of fast_scan

[MouradZoghbiWork]

I try to get result of fast_scan (class1 every 1 minus) :

utilities.print_with_log("########### START FAST_SCAN CLASS1 EVERY 1 MINUTE ###########")
r = dnp_client_ip1.client.fast_scan.Demand()

utilities.print_with_log("########### WAIT NEXT 1 MINUTE ###########")
start_time = time.time()
while time.time() < (start_time + 60):
    # change data point value
    time.sleep(2)
utilities.print_with_log("Next minute, Expected = 50")

how to get scan result in some variable (when i print r it return None)

Hi @MouradZoghbiWork , fast_scan is obsolete. Please instead use run_master.py for inspiration, especially https://github.com/VOLTTRON/dnp3-python/blob/main/src/dnp3demo/run_master.py#L154-L157.

Example usage:

run the script: then typing in dd.
