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
