2. Set EPICS_BASE, EPICS_HOST_ARCH
3. cd $EPICS_BASE/modules

   SUBMODULES += pcas
   pcas_DEPEND_DIRS = libcom
   

6. cd $EPICS_BASE

2. Test with camonitor adei:mos-Monitorspeczeus_rep-0-0

Integration with Archiver

12670 is a very big number to use the webapp for. Thus we use the Archiver API directly. POST request to EPICS Archiver Appliance with PV names in the request body

curl -X POST --header 'Accept: application/json' --header 'Content-Type: application/x-www-form-urlencoded' --data '@./archappl-requestbody' http://replay-archappl.kaas.kit.edu/mgmt/bpl/archivePV
