Features
The integrated system bus in the 9300 controller serves to extend the controller functions. These are:
z Parameter selections
z Extensions by decentralised terminals
z Data exchange from controller to controller
z Operator and input devices
z External control and host systems
Without having any experience with the bus system, the user is able to carry out e. g. a data exchange
from one controller to another with digital control signals, speed signals, and torque signals. If the
user knows how to configure the function blocks this can be done with the help provided in chapter
”Working with function blocks”.
Five input channels and five output channels are available for data exchange and can be used
independently. Two parameter channels are included (SDO = Service Data Object).
