+ | ===== Context | ||
+ | |||
+ | | Here discribed electronic builds the front end beetween hardware of an air pressure drive that moves different diagnostic device into a vacuum pipe and the controlling PLC system. It enables fast replacement of defect parts a the drive by simular normalizised spare parts by plug and play and some cable ties. It although ensures strightly hardware based interlocking of up to six drives blocking each others if necessary to prevent in chamber collisions, for example at on vacuum chamber. No high end electronic has to be placed close to beamline with possible hard radiation ocourring.| <color white> | ||

+ | | **Six fold node**: This metall box placed close to diagnostic chambers collecs up to 6 single pressure drive control cables to a bigger one that is the connection to the PLC apart from the beamline. It has for each of the possible 6 drives a port for hard wired blocking one of the other drives in case of use of first: Cause diagnostic devices carried by pressured air drives might varry at an experimental accelarator this prevents collisions in one chamber completly seperate from any software or comunnication faults. | <color white> |
