Solenoid Controls in the Hall
- We decided to go to a Ethernet only system (EN2T only) and skip ControlNet.
- greater configuration flexibility.
- eliminates possible need for running copper ControlNet cable from the hall to the counting house.
- Fernando very much wants to minimize such copper connections as they potentially can introduce noise into the electronics.
- cheaper to implement redundant PLC system.
- Josh ordered a "sequence of events" module to help with debugging trips.
- will test this and many other things in the controls test stand
- do we want to monitor circuit breakers?
IOC vs PLC vs Mixed System
Much discussion on relative merits of the various systems. Concerns:
- cost: PC104, etc
- what hardware is needed
- development software costs: time, manpower, licenses
- complexity
- obsolescence
- many other issues...
Mantis
We are using the Mantis system for task tracking. Everyone needs to log on and register as a new user if you haven't done so already.
