Modernisation of the CIP station in a dairy – Xinje TG panel
Xinje products can successfully serve as replacements in the production process. Thanks to their attractive price, they stand out from their more expensive competitors, offering the same functionality. An example of Xinje’s use as a replacement is our modernisation of the visualisation system at a washing station in a dairy plant.
The customer had a Siemens panel that was damaged, and replacing it would have been very costly. He decided to use a Xinje TG series panel as a solution. The upgrade involved creating an identical visualisation from the damaged panel and running it on the Xinje panel.

Main features of the solution:
- replacement of the Siemens operator panel with Xinje,
- maintaining full functionality of the target visualisation while increasing its readability thanks to the use of a larger screen,
- modernisation of the station with additional types of washing,
- communication with the S7-300 controller via Ethernet protocol.

Modernisation
The visualisation on the Xinje operator panel was transferred from the Siemens OP177a panel to the TG 765-ET series panel, with Ethernet protocol support. Communication between the panel and the S7-300 controller was established via the PROFINet protocol. The full functionality of the washing station was recreated on the Xinje panel, and in the next stage, an additional washing programme was added at the customer’s request.

Thanks to scripts written in C on the Xinje panel, it was possible to reproduce advanced visualisation from the Siemens panel. In addition, these scripts allowed for the addition of an extra washing programme without the need to modify the programme in the S7-300 PLC controller. The settings for the extra washing programme are stored in the panel’s memory registers, and the extra programme is based on the existing one, replacing the parameters stored in the controller’s memory.
