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?

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

PLC Main Loop

At start Only allowed if values are
referenced? Mode depends on mode procedure During

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.
