Read V20 alarm code over USS

Hi,

I use V20 driver and s7-1500 PLC and communicate with USS protocol.

Everything is okay but I want to display the alarm codes of the drive on HMI. But I don't know it is possible or not. I see only the parameter about faults on V20 ->r0947 "last fault code" but there is no parameter about alarms.

Is there any way to do this? User defined outs of USR_Drive _Control block like Status2,3 etc.

Thanks.

Check r2110, it stores 2 active and 2 historical warnings in indices [0] to [3].

[0] and [1] are active warnings and [2], [3] are the historical ones.

Is it stores warnings or warnings and alarms? I am asking this because in V20 manual faults and warnings listed in same topic but alarms are seperate. And there are two parameters for faults and warnings. No parameter exist for alarms. 

There are two types of messages: faults and alarms which are also called warnings.

A fault causes V20 to stop and alarm/warning doesn't and usually precedes a fault.

New question published by edw44 is split to a separate thread with the subject How to read the current with USS_read_Param?.
