3 SYSTEM SETTINGS
3.1 INTRODUCTORY REMARKS
All the functions of CANDPSX can be configured, therefore this module implements an internal
database with a set of parameters for setting the operating characteristics.
Any changes to configuration parameters are actually applied only when the module is switched on
again or reset after the settings have been saved to non-volatile memory (see § 30).
3.2 OPERATING MODE
CANDPSX supports three operating modes for real-time data exchange between a Profibus-DP
and a CAN bus network.
