4 Functions

4.1 Functionality of the device

Compartment fine positioning is used for the detection of so-called hole positions (hole or reflector) that are set into crossbeams of the high rack.
Functions
• Two different hole positions can be detected, A check program is stored on the device for each detection position. The distance between the rack profiles and the lens cover of the device can be specified for each hole position.
• The control uses a signal that is constantly applied at digital switching inputs IO2 and IO3 to deter­mine which check program is active; see chapter 4.4 "Process sequence".

4.2 Check programs

The
Rack Near
measuring tool in the check program are used for this purpose.
• With activation, compartment fine positioning for the started or stopped via digital switching input I01.

Digital switching outputs IO5 … IO8 are permanently on as long as the control performs compart­ment fine positioning via the device.
• To compensate for the difference in position between loading position and unloading position of the high-bay storage device, a shift of the coordinate origin is defined for the current check program by entering an offset value.
On delivery, two check programs are set up in the device for programs are optimized as follows:

4.3 Diagnostics – image transfer

For diagnostics, the smart camera images can be stored (parallel to the check program procedure) in the ring buffer.
• Saving the images in the ring buffer is started (IO4=1) and ended (IO4=0) via digital switching input IO4.
• A maximum of 14 images are stored in the ring buffer, with the oldest images being overwritten once the buffer is full. 14 images in the ring buffer correspond to approx. 500 ms of positioning.
The images can be transferred to an FTP server via FTP for diagnostics:
• To transfer the images, an M12 Ethernet connection cable must be connected between the smart camera and a PC or laptop as FTP server. Alternatively, the smart camera can be connected to a network in which the FTP server can be accessed.
• Data transmission via FTP:
• The FTP access data must be entered in the webConfig tool.
• Data transmission via FTP must be activated in the webConfig tool.
The images are not transferred from the ring buffer until after the trigger signal (IO1=0) has been reset.
• Upon conclusion of diagnostics, data transmission via FTP must be deactivated in the webConfig
tool. The M12 Ethernet connection cable can be removed after completing diagnostics.
• The FTP access data can be stored in the smart camera for later diagnostics.
• Details on the settings in the webConfig tool: see chapter 9 "Extended configuration –
Leuze electronic webConfig tool".

NOTICE
Incoming signals are ignored while changing the check programs!
While the check programs are being changed internally, additional incoming signals are ignored,
including the trigger signals.
The internal changeover of the check programs lasts up to 300 ms.
• Shortly before reaching the target position (capture range), a permanently applied signal at switching inputs IO2 and IO3 specifies the check program for the device. Program 1: IO2=0 and IO3=0, corresponds to Program 2: IO2=0 and IO3=1, corresponds to
• The control activates the test procedure, i.e., compartment fine positioning, by setting switching input IO1=1. Tool evaluation, i.e., execution of the check program, is started beginning at this point in time. Digital switching outputs IO5 … IO8 are output statically as long as the specified hole position is detected in the respective tool.
• At the end of check program execution, a check for the presence of the activation signal (IO1=1) is performed. If the activation signal is still present, the check program is immediately executed again.
• If the activation signal (IO1) is reset while a check program is being executed (IO1=0), this check continues to run. Switching outputs IO5 … IO8 are then set to 0.
• If switching output IO5 … IO8=1 and the high-bay storage device has reached the target position, loading or unloading is started.
• Parallel to the test procedure, switching input IO4 can be used to start (IO4=1) or end (IO4=0) the saving of images in the ring buffer. The user can thereby separate the check program procedure from the image.
