The milling process is completely automated through the use of a Siemens S7400 PLC connected to the Siemens WinCC supervision system.
Through the graphical supervision interface, it is possible to monitor in real-time all the states of the installed items and immediately display any alarms that may occur. The whole grain processing is divided into sections.
Each section is equipped with its own start and stop commands, such as the setting of the operating parameters. Example of operating parameters are :
- source silos
- destination silo
- quantity
Particularly important is the integrated yield program that allows continuous monitoring of the production yield of the wheat being processed and also allows the control of grain moisture.
The graphic interface has been designed to be simple and intuitive for the operator
This is the actual PLC configuration:
There is a central rack with a Siemens S74010 CPU with an ethernet interface for PC connection e a Profibus port to manage the following remote items:
- 7 electrical board with remote I/O installed on different floors
- 1 Hygros-tec for moisture control (Celmec)
- 4 Buhler dosers for silo extraction
The PC has the control of the BER scales by serial 485 connection. In this way, it is possible to take the right production rate for the yield calculation.
The Supervisor is developed in Siemens Wincc Scada. The supervisor is running in a virtual machine easy to replicate in order to avoid the stop of the supervisor for a PC HW problem. Equipment and material as it is.

Excluded:
