The vacuum system of ALPI (Acceleratore Lineare Per Ioni) accelerator at LNL (Laboratori Nazionali di Legnaro), including around 40 pumping groups, was installed in the 90s. The control and supervision systems, composed by about 14 control racks, were developed in the same period by an external company, which produced custom solutions for the HW and SW parts. Control devices are based on custom PLCs, while the supervision system is developed in C and C#. The communication network is composed of multiple levels from serial standard to Ethernet passing true different devices to collect the data. The obsolescence of the hardware, the rigid system infrastructure, the deficit of spares parts and the lack of external support, impose a complete renovation of the vacuum system and relative controls. In 2022 the legacy high level control system part was substituted with a new one developed in EPICS (Experimental Physics and Industrial Control System) and CSS (Control System Studio)*. After that, we started the renovation of the HW part with the installation and integration of two new flexible and configurable low level control system racks running on a Siemens PLC and exploiting serial server to control the renewed pumping groups and pressure gauges. The plan for the next years is to replace the legacy hardware with new one retrieving spare parts, provide service continuity, improve PLC software and extend the EPICS control system with new features. This paper describes the adopted strategy and the upgrade status.
