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
