Wide variety of I/O types: Analog (high level, low level, and
temperature), digital, and control I/O.
Significant reduction of installation costs:
Significant reduction of installation costs: Significant reduction of installation costs:
Significant reduction of installation costs: I/O assemblies
combine chassis, cabling, I/O electronics, power conversion,
and termination into one device. Distribution of I/O reduces
cable costs.
Reduction in total operating costs:

Reduction in total operating costs: Simplified user configura-
tion with no calibration required, no address switches to set,
and downloadable firmware.
Compatibility with existing systems: Compatibility with existing systems: Compatibility with existing systems: Compatibility with existing systems: Works with both the
Harmony bridge controller and Harmony area controller;
works in combination with Harmony rack I/O and INFI 90
OPEN I/O.
Advanced features: Advanced features: Advanced features: Advanced features:
•
Downloadable firmware eliminates PROM changes.
•
User-assignable software device labels eliminate the need
to manually set hardware addresses.
•
User-assignable I/O channel labels simplify configuration.
The same label can be used to identify an I/O channel and
to define a tag in the system database for easier I/O point
recognition.
•
Advanced diagnostics of I/O block, I/O channel, and Hnet
traffic identifies system problems.
•
I/O status can be inhibited from contributing to block sta-
tus, eliminating nuisance alarms.
•
Manual override of I/O channel values simplifies system
maintenance.
