ABB Bailey Infi90 Harmony System - Symphony Plus (S+) shutdowns
Limitations of Bailey Infi90 System. The plant went into several shutdown and initial investigation showed jamming of Prodfibus communication and disturbance on Modbus.

Hi,

We have S+ running in our desalination plant with processor HPC800. We have many Modbus links (Modbus Ethernet) with the field side on slave Modbus and we have Profibus between servers and profibus network+ with valves/transmitters. The plant went into several shutdown and initial investigation showed jamming of Prodfibus communication and disturbance on Modbus.

What are the recommendations to prevent such incidents from recurring?

Thank you.
