- 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?
- How much reliability do we need? What are the consequences of occasional network loss?
- What are the mechanisms that cause loss of network connection other than hardware failure?
- 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 unless we are worried about loss mechanisms other than hardware failure.
- Still To Do
- Test what happens if an Ethernet cable is unplugged.
- Notes
- 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.
