The expansion backplane is a key component to the ability of the
ROC827 to expand its I/O capabilities to meet your needs. The ROC827
base unit can accommodate up to four additional expansion backplanes,
which easily snap together. This increases the total number of available
I/O slots to 27. Refer to Chapter 2, Installation and Use, for instructions
on adding backplanes to the ROC827 base unit. Refer to Chapter 3,
Power Connections, to assess the power requirements for any particular
I/O configuration.
™ Fieldbus Interface
The F
OUNDATION
based solution that, when connected to a ROC800-Series controller,
enables you to configure and manage up to four H1 interface modules.
You can house the FFbus Interface either as a stand-alone unit or as part
of a Series 2 ROC800 assembly.
Each H1 module can communication with up to 16 remote fieldbus-
compliant devices, enabling you to manage up to 64 remote fieldbus
devices for each FFbus Interface.
Additionally, the Interface is designed to share fieldbus device data with
one or more ROC800s, creating a broad network of device information.
For detailed information on how to install and use the FFbus Interface
with the ROC800, refer to the F
Instruction Manual (Form A6259) and the Field Interface Configurator
User Manual (Form A6250).
