Function Codes
Function Codes
When interfacing to Harmony I/O blocks, the controller uti-
lizes single channel I/O function codes:
•
Analog input/channel (FC 222).
•
Analog output/channel (FC 223).
•
Digital input/channel (FC 224).
•
Digital output/channel (FC 225).
These single channel function codes simplify configuration:
one function code configures one channel. A single I/O device
definition function code (FC 221) groups the single channel
function codes for an entire I/O block. Refer to the

Compatibility
The Harmony I/O system is fully compatible with existing
INFI 90 OPEN systems. The I/O system can be integrated into
established installations that currently use INFI 90 OPEN I/O
to interface and process input and output signals. Or, the I/O
system can be installed to replace existing INFI 90 OPEN I/O.
The Harmony controller can communicate with Harmony I/O
and INFI 90 OPEN I/O simultaneously. Communication is over
Hnet for Harmony I/O blocks and over I/O expander bus for
INFI 90 OPEN I/O.
