	At CERN there are currently about 200 ventilation air handling units in production, used in many different applications, including building ventilation, pressurization of safe rooms, smoke extraction, pulsion/extraction of experimental areas (tunnel, cavern, etc), and the ventilation of the computing centre. The PLC applications which operate these installations are currently being revamped to a new framework (UNICOS CPC). This work began 3 years ago, and we are now in a position to standardize the development of these HVAC applications, in order to reduce the cost of initial development (including specification and coding), testing, and long-term maintenance of the code. In this paper the various improvements to the process with be discussed, and examples will be shown, which can thus help the community develop HVAC applications. Improvements include templates for the "Functional Analysis" specification document, standardized HVAC devices and templates for the PLC control logic, and automatically generated test documentation, to help during the Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) processes.

	PLCs are widely used to control and monitor industrial processes at CERN. Since these PLCs fulfill critical functions, they must be placed under permanent monitoring. However, due to their proprietary architecture, it is difficult to both monitor the status of these PLCs using vendor-provided software packages and integrate the resulting data with the CERN accelerator infrastructure, which itself relies on CERN-specific protocols. This paper describes the architecture of a stand-alone "PLC diagnostics monitoring" Linux daemon which provides live diagnostics information through standard means and protocols (file logging, CERN protocols, Java Monitoring Extensions). This information is currently consumed by the supervision software which is used by the standby service to monitor the status of critical industrial applications in the LHC and by the monitoring console used by the LHC operators. Both applications are intensively used to monitor and diagnose critical PLC hardware running all over CERN.
