  • Should we use ControlNet as well as Ethernet/IP in the hall?
    • Notes
      • Is there really a network reliability problem?
      • Would we have to run a copper line to the counting house?
      • Should we use an additional PLC in the hall?
      • Should we locate the main PLC in the hall?
    • Resolution
      • Bryan and Brent say the high-class switches we will use in the hall are extremely reliable, as reliable as the PLC itself, so there doesn't seem to be a good reason to use ControlNet.
    • Still To Do
      • Test what happens if an Ethernet cable is unplugged.


  • When should we use a PC104 vs an IOC on a PC vs direct PLC control?
    • Notes
      • Should the FDC gas system use just PLC control and not use a PC104?
      • The FCAL CAN system probably requires an EPICS buffered virtual device running in a PC104.
      • Should we mix EPICS and PLC control in a single system?
    • Resolution
    • 'Still To Do
      • Need to see full FDC/CDC gas system P&I diagram.
