Function

I/O modules are signal modification devices. Field signals from a hazardous area
are prepared for controllers or process control systems in a safe area. The slots for
the I/O modules on the backplane have equal status, meaning functions can be
arranged side by side as required.
Adapters form the interface between the I/O modules and the process control
system. An adapter can control up to 45 I/O modules and transfer their signals
across EtherNet/IP. The adapter converts the protocol of the bus that is
integrated in the backplane to the protocol of EtherNet/IP. For more
information, see Adapter on page
Power supplies provide power to the I/O modules and the associated adapters on
a backplane. The slots for power supplies and adapters are mechanically coded on
the backplane and marked with a label.
