Hi,
I am running a P4P server on an embedded system and offer the following structure:

epics@felpvagate:~$ pvinfo  FHIFEL:llpg_1
FHIFEL:llpg_1
Server: 10.0.0.87:5075
Type:
    structure
        ushort Ch1_Width
        ushort Ch2_Width
        ushort Ch1_Delay
        ushort Ch2_Delay
        ushort Ch1_ExtraDly
        ushort Ch2_ExtraDly
        ushort Ch1_Atten
        ushort Ch2_Atten

Unfortunately, the archiverAppliance cannot monitor/archive these.

Was ist der beste Weg um diese Werte zu archivieren?

1.) Should the 8 values be made available as ‘individual’ scalar PVs on the embedded system as well?

2.) Run a ‘converter’ on another system that maps the custom struct to scalar PVs?

3.) Another idea ?

Danke Heinz
