8-2 Communicate from an SLC 5/05 Controller to an SLC 5/03 Controller over an EtherNet/IP Network
Hardware Configuration
In this hardware configuration, an SLC 5/05 controller communicates to an
SLC 5/03 controller over an EtherNet/IP network.
• The SLC 5/05 controller initiates a message. (1)
• The message is sent over an EtherNet/IP network to a 1756-ENBT
module. (2)
• The message is then sent over the backplane to a 1756-DH485 module.
(3)
• The 1756-DH485 module then sends the message through channel A
and link couplers to the SLC 5/03 controller. (4)
