IOCs

binary

• identical for all hadcons

startup cmd file

st.cmd

sources st_${HOSTNAME}.cmd for host specific database

database

• makes extensive use of template/substition functionality of EPICS
• mainly connects via streamDev protocol functions to the API of Hadcon's micro controler
  • using as asyn port hadcon's internal serial interface device /dev/ttyS1 connected to the μC
• takes care of non-conflicting access to the μC
  • hadcon_global_scan.template, which calls task specific "globals" initiating the read/write action
    • hadcon_atmel_adc_global.template
  • or special tasks:
    • RPC gas system monitor:
      • hadcon_global_scan_rpc_gas_system.template
  • ...
• other global, singular to the host, templates/db
  • hadcon_global.db
  • hadcon_debug_global.db
  • hadcon_show_global.db
