I have a Modicon Quantum installed in a large mineral seperation plant, the programing software is concept v2.6. The plant has about 2000 I/O points of which there is about a 50/50 spilt between analog and digital. These are currently all on the modicon 800 series racks as the quantum replaced the 984B. The plant is about 500 m from the plc. The racks are localized in the plant.
We are looking at installing about 100 new analog points and am lookinf at a bus as apposed to installing new racks.
In time we would like to put the existing "multi-parameter, down-loadable, high-level" instruments onto the network as aposed to just getting a 4-20ma signal.
Please give me your informed opinion as to which bus systum would be better suited to my application as discribed.
