Diagnostics - Image Transfer; Process Sequence - Leuze electronic LSIS 472i Series Operating Instructions Manual

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".

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.
