EtherNet/IP and 1757-FFLD
Linking Device Example To set up communication between a controller and a linking device, you need a
bridge module and Logix5000 Logix Blocks. Logix Blocks, which transfer signals
between a ControlLogix environment and a fieldbus environment, have to be
configured by using RSFieldbus software and RSLogix 5000 software.
RSLogix 5000 software sees the linking device as a remote chassis with a virtual
backplane with up to 16 available slots. When a Logix Block is added, the linking
device is recognized by RSLogix 5000 software as an analog module. Each
configured Logix Block module takes one slot and is assigned a unique slot
number in the chassis.
A communication module, such as catalog number 1756-ENBT, establishes the
EtherNet/IP address to allow the 1757-FFLD linking device to communicate
with the ControlLogix controller.
For topology, equipment, and wiring details, see the FOUNDATION Fieldbus
Design Considerations Reference Manual, publication
RSFBUS-RM001 .
Figure 1 shows the RSFieldbus workstation connected directly over the
EtherNet/IP network to the ControlLogix chassis.
