The vacuum control system of the ESRF electron Storage Ring (SR) is in operation since more than ten years now. Apart from difficulties to have appropriate support for the old system, we start facing problems of aging and obsolescence. We have been reviewing our philosophy of data acquisition and remote control in order to upgrade our systems with state of the art technology by taking into account our operational experience. We have installed shielded "intelligent" devices inside the SR and took advantage of the latest developments linked to new communication technologies and standards, such as TCP/IP MODbus protocol and WEB server based instrument control. This presentation outlines our present work dedicated to the ESRF temperature acquisition system based on Programmable Logic Controllers (PLC), and new developments regarding the user interface in the control room. Several examples show the importance of surveying the temperatures in order to identify various mechanical or operational problems which allow us to anticipate later failures and provide us with an additional machine diagnostic tool.

The ESRF is in operation since more than ten years. Due to the aging vacuum system, we are faced to different kinds of failures such as air or water leaks, overheating of RF-liners or poor chamber alignment. In order to anticipate these failures and therefore reduce down times, we started to develop new diagnostic tools which allow us to detect much faster and with more precision any possible failures or malfunctioning of our vacuum system. Also driven by the increase of machine performances and the continuous vacuum installations, we search for new tools to safely commission such upgrades. This paper outlines our work on the development of a new vacuum user interface, which not simply reflects the actual status of our vacuum system, but which also provides us with a dynamic survey of computed vacuum signals highlighting unusual vacuum behaviours.
