bilan
Good

Production applications ready on due time

Production methodology allow easy and clean maintenance

All application under one supervision system

Recurrent communication problem solved before CD

Coherent and efficient powering and networking schema (no stop at last powercut)

CNIC Implementation transparent.

Operators trained and happy with proposed HMI

Remote access via terminal server

Not so good

Too Many versions for logic that have induced some regression during system commissioning

Each integration of a new system in PVSS can induce limited but painful regressions if strict procedures are not followed

Need for reverse engineering tools

One PLC stop that have induced several hours of delay

Control loop on Ethernet are at risk

Some discrepancies between production and sector HMI to solve

Still some requirements to implement

Too many users on terminal servers need of clusters
