Chapter 1 Digital Module Operation in a Control System
Remote Compact 5000 I/O Digital Input Modules
Remote Compact 5000 I/O digital input modules broadcast their input data
to the Compact 5000 I/O system backplane at the time that is defined in the
RPI. The input data consists of channel and status data.
At the RPI, the following events occur.
1. The remote input module scans its channels for input data.
2. The module sends the data to the remote system backplane.
3. The Compact 5000 I/O EtherNet/IP adapter sends the data over the
EtherNet/IP network.
4. One of the following:
• If the controller is directly connected to the EtherNet/IP network, it
receives the input data immediately.
• If the controller is connected to the EtherNet/IP network through
another communication module, the module sends the data to its
backplane and the controller receives it.
IMPORTANT This can only be the case if a ControlLogix 5580 or
GuardLogix 5580 controller owns the I/O module.
CompactLogix 5380, CompactLogix 5480, and Compact
GuardLogix 5380 controllers do not support the use of an
EtherNet/IP communication module in the local system.
