Abstract :
A programmable logic controller, color graphic operator interfaces, and an analog data-acquisition system have been added to the helium liquefier and distribution system at the DIII-D extended monitoring. Control capability, as well as centralized datalogging, trending and alarm reporting is described. Other objectives of the upgrade included offsite remote monitoring and control through a phone modem, and a hardware basis for automation of liquefier operation and maintenance. It is now also possible to accomplish connection and coordination with other DIII-D control systems. It was required that most of the installation and checkout of the new control system be done during operating periods. For this reason, and for reliability concerns, the upgrade hardware was designed and installed as an additional independent system rather than a replacement control system
