4.2.4.1
Direct access to the field devices
• The controller and the IPC (Visu) access the fieldbus independently of each other.
• The visualisation (Visu) can access the parameters of the field devices and the parameters of the
controller.
• Depending on the bus system used, several bus masters that are independent of each other can
be used.
• The visualisation may impact the real-time capability of the bus. Therefore this configuration is
only suitable for Motion systems to a limited extent. (It also depends on the bus system used)
Direct access to field devices is possible for the following bus systems:
• CANopen
Details regarding the suitability of the respective field devices can be found here:
Note!
• Direct access to the field devices connected to the fieldbus ensures a maximum
independence of the two systems, but is rarely reasonable in practical operation.
• The configuration with independent control and visualisation systems is only
recommended for systems without a Lenze control system!
