  • Should we use ControlNet as well as Ethernet/IP?
    • 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?
    • Note: Bryan and Brent say the high-class switches we will use in the hall are extremely reliable, as reliable as the PLC itself.


  • When should we use a PC104 vs an IOC on a PC vs direct PLC control?
    • Should the FDC gas system use just PLC control and not use a PC104?
