is there a common behavior for command 6, when the Loop Current Mode is set to disabled? Specification says the loop current should be set to the minimum value required for the field device operation. In my case I have a 4 - 20 mA device. The minimum value required would be around 3 mA, but this value is sometimes used by devices for Fault indication.
I checked another hart device and they keep the loop current at the last value before disabling.
