Modification and expansion in existing Simatic S5 155H automation system and COROS for dairy.
Raw Milk Storage silo is added to increase productivity and hence the following sequences are added.

• Milk transfer sequence from Tanker to Raw Milk Silo
• Milk Transfer from Raw Milk Silo to Milk Processing lines
• CIP of Raw milk silos & transfer lines
• Communication with other PLCs in the plant.

Since this is a running plant, modification is done with negligible shutdown time, primarily in the night shift.
