(1)
The module is a scanner (for example, the module can originate connections to remote I/O).
(2)
When it functions as an I/O bridge, the module can (in conjunction with the controller) originate connections to
remote I/O.
(3)
When it functions as a messaging bridge, the module can function as a gateway from one network to another
network or backplane without a controller program. To enable gateway functionality for the 1784-PCC card,
RSLinx Gateway is required.
(4)
When you use the CompactLogix 1769-L32C or 1769-L35CR controllers as a bridge from ControlNet to
DeviceNet, you must use a 1769-SDN module in the local chassis.
(5)
When it functions as an I/O adapter, the module can interface to I/O and serve as the target of a remote I/O
connection from a controller.
The ControlNet communication modules:
• support messaging, produced/consumed tags and distributed I/O.
• share a common application layer with DeviceNet and EtherNet/IP.
• interface via RG-6 coaxial cable or 200/230 micron HCS (hard-clad
silica) fiber optic cable.
• require no routing tables.
• support the use of coax and fiber repeaters for isolation and increased
distance.
