and press ‘Apply’ again - otherwise the updated point(s) will be active only until the first power
reset.

•

Attention: While executing function “Re-Start BM102”, error messages could appear (“error

reading xxx: field device did not respond”). This is due to the fact that AMS tries to refresh its
values while the BM102 is not able to answer (initial self test : about 30 seconds).
! After having executed this function, just close all AMS screens concerning the field device

(Process variable screens, Configuration properties screens,…) and reopen the desired AMS
screens.

•

While changing the threshold value, a pre-edit action is executed in order to refresh the distance

value.

•

Calibration Management functions are not supported.

4.3 Shortcomings

•

With AMS 5.0, when we create or erase a volume table, the window “Process Variable“

could not be refreshed (bargraphs of volume measurements are not displayed or removed).
We must close the window and open a new one to solve the problem.

•

When we import a configuration from the HART



communicator (data type = Standard) to

AMS (import offline configuration), the values of 2 parameters are asked:
Function I and the Number of point of the volume table.

Function I items could not be available. First enter the number of point (0), after that click
on the window (anywhere). The Function I items should now be available.

•

If we use the “Full (for PC)” data type, there is no problem when saving the configuration on
the HART Communicator and transferring it to AMS (and vice versa). In case do not login
as specialist, specialist parameters will not be saved. Moreover when sending data to the
device, 3 errors messages could appear when we want to write the “Gain”, the “Release
number” and the “Electronic offset”. These messages appear because there is no write-
command for these parameters. We can not modify them directly (their values are calculated
automatically by the device). This is the reason why we can not transfer the value of these
parameters from one device to an other. Don’t worry about these messages.

•

With AMS, in Offline Configuration, when we get a configuration from the history and

when we transfer it to the device, we could have the following 2 errors:

- Error writing Lev,
- Table not monotonous.
The second message can appear even if there is no volume table (number of point = 0). Don’t
worry about these messages.
