14. 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 Bilan Ph Gayet AB/CO IS
