  12. H K NI EF PLC initial procedure start init • At start; • First check mode to establish the right communication? • Or always in physics mode? • Check or this command is allowed? • A priori out of reference • Inhibit beam injection • Goto reference position • Error 101 on time out +? (other procedure) • Enable beam injection • Goto desired position (other procedure) • So far it means that there is possible a beam without knowing the position of the detector? • Procedure delivers a status flag that all values are referenced? status check n physics mode out of reference physics mode n master limitsactive physics limitsactive disable beaminjection Zcommand ready n time out n Set reference values error105 error101 Goto main-loop enable beaminjection stop

  13. H K NI EF PLC mode procedure • Physics mode or Master mode. • Status are presented to SCADA and portable display • Physics mode: • Accept only commands via SCADA system • Narrower limits then master mode • No password protection • No change allowed of the mode • Master mode: • Accept only commands by portable display • More limit privileges then physics mode • Only via password protection changing of mode

  18. H K NI EF Commands Available commands to the stepper interface; XL XR Y Z Annn P L Q goto reference position (takes 300 seconds maximum for XL and XR or 30 seconds for Y axis)check moving with the potentiometers goto nnn absolute postition (takes 300 seconds maximum for XL and XR or 30 seconds for Y axis) nnn in steps, value between 0 and 1.400.000 (35.00mm) check moving with the potentiometers read the position of the stepper read the actual value of the resolver equal on the stepper (+/- 25 steps) quit the command (Z and A), stops the steppermotor.
