Attention!
Using the PROFIBUS and SSI interface simultaneously
:
The SSI interface settings are performed by the PROFIBUS. If settings which differ from the
default settings for the parameters, are to be used, they must be configured via module 17
(SSI interface).
Using the SSI interface without PROFIBUS
:
For this operating mode deactivate the PROFIBUS via the display (PROFIBUS = OFF).
Default parameters are stored in the laser measurement system for the sole use of the SSI
interface. The preset default parameters can be changed at any time via the display.
This also applies when using parameters which do not relate directly to the SSI interface
(for example: I/O 1 or I/O 2, position value or others).
The SSI interface remains active even during parameter enabling. Changes to parameters
have an immediate effect.
