Central Buffer Tanks and Product Flow Control

Performed the software design and implementation of a centralized buffer tank system with the purpose of storing large quantities of product and being the core decision point of flow control. Product could be requested by two separate drum-filling lines, and independently sterilized and CIP'd. This system had an interface to 4 other systems, realized over an ethernet/IP network. The controller used was a Siemens 1500 series PLC, and a Siemens HMI, integrated to the program via WinCC. The HMI was build to give an overview of the system, and make it as user-friendly as possible for the operators of the plant.
