Front end electronic for pressured air drives

PA-Terminal: This small electronics will be mounted at future FAIR compressed air driven drives. PA-Terminal is seated direct at the drive and enables by several ports fast exchange of endposition sensors, pressure switch and magnet valve cabling at the drive. Apart from the very straight hardware based sensor signals that are passed through to a PLC cotrol in far distance that device includes a micro contoller based movement counter. It's counts and ID are stored in EEProm to be present even if that drive is not in use laying in a stock. A feature is the possibily to remortly read it out by an RS485 field bus. Thus maintanance personal can read out the counters without need of direct inspection. Because this device is close to beam line the programming does excecute continiously redundency tests of stored values in three different places including the number of failures detected thereby. Of cause this movement values are registered parallel in accelarator control system.

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.

During acceleration in the SIS18, and slow extraction to the HEBT lines and experiment caves as well, the transported and/or lost particles are detected. Proportional pulses, generated by various signal sources (IC, SEM, BLM, collimators) have been processed by the so called “Walterkisten” for nearly 20 years. As these devices are now outdated and not servicable anymore, a FPGA-based functional replacement with ETH interface and FESA compatibility will be designed, abandoning the connection to the old GSI control system. overview ...

The system called “Walterkisten” (discribed in topic above) has to be replaced in near future. This will be done by the here sketched system.

A first step on that way is a unit called “SeleonST”: this unit can be remotly controlled via Ethernet from any PC in network. It's task is to control all set and read out values of actually 22 connected current to frequency converters and pass their counting values to VME-crates with NIM-counters. SeleonSt is build especially for vacuum group and SIS18-people in order to observe beamlosses at the SIS18 appatures. It should give an idear of the losses to project vacuum coating in future. It is able control the 22 IFC asynchron and independent to existing controll system:
