SIPLACE Vision - Sensor Overview
The digital SIPLACE Vision solution is another step towards the satisfaction of customer demands for
greater speed, flexibility and robustness.
► To connect to the folder on the SIPLACE Pro comput-
er, you need to enter the name of a user with the re-
quired permissions for the SIPLACE Pro computer in
the following login window. The standard is User
name (Benutzername). Administrator
Password: <standard password for administrator>.
Confirm your entries with OK :
► The connection will now be established to the sub-
folder on the SIPLACE Pro computer and will be
made available for future access as driveZ::
► The machine data or the entire station computer data
folder can now be copied to this drive and is available
here for data recovery purposes.
To differentiate multiple data backups in the same
subfolder, you can rename the backup or WinZip file
after copying e.g. by adding the date:
NOTICE
At the SIPLACE Pro computer, you can now save the data on an external data carrier.
This procedure for data backup/recovery can be set up for all SIPLACE station computers.

Advantages of the digital Vision system:
▪ Robust and fast computing algorithms
▪ Flexible measurement processes
▪ Intuitive graphical user interface
▪ Geometric description of components at the machine
▪ State-of-the-art digital camera hardware
▪ Homogenous illumination of camera field of vision and components
Each C&P head has its own digital component camera.
