Controlnet And 1757-Ffldc Linking Device Example - Allen-Bradley 9308-RSFB64ENE User Manual

ControlNet and 1757-FFLDC
Linking Device Example
Item Description
1 ControlLogix controller with 1756-ENBT and
1756-CNB modules
2 Host computer and OPC server
3 Stratix 8000 switch (optional)
4 24V DC power supply
The ControlNet network combines the functionality of an I/O network and a
peer-to-peer network, providing high-speed performance for both functions.
Devices can be scheduled for deterministic transfers of important data in
addition to unscheduled time intervals for non-critical information.
The 1757-FFLDC linking device has the option of being programmed for
scheduled, repeatable data transmissions on the Connection tab of the Module
Properties dialog box in RSLogix 5000 software. You must also run RSNetWorx
software to schedule the Logix Block to the network connection.
Figure 2 shows the RSFieldbus workstation bridged from Ethernet to the
ControlNet network via the ControlLogix chassis.
