Online Configuration
WBPEEUI240766B0 2 - 11
the ASI module must be fed to a standard exception reporting
block. Refer to
Section 6 for more information.
Online Configuration
All specifications in FCs 215, 216, and 217 associated with the
ASI module can be changed during online configuration. When
changes are made to the input channel parameters (FC 216),
the channel will hold the last value for a short period, the sta-
tus remains unchanged during this period. This hold time is
based on the number of channels that were changed during
online configuration.
NOTE: Plan on a hold time of four seconds (worst case) for each FC 216
changed during online configuration.
Logic Power
The ASI module receives its power (+5 V) from the MMU back-
plane. Power connects through the top 12-pin card edge con-
nector (P1) at the back of the ASI module.
Mounting Hardware
Harmony rack I/O modules and termination units mount in
standard ABB Automation enclosures (CAB-01, CAB-04,
CAB-12). The number of modules that can be mounted in a
single cabinet varies.
An IEMMU11, IEMMU12, IEMMU21, or IEMMU22 module
mounting unit and an NFTP01 field termination panel (FTP)
are used for module and termination unit mounting respec-
tively (Fig.
2-2 ). The mounting unit and termination panel both
attach to the side rails in standard 483-millimeter (19-inch)
enclosures. Front mount and rear mount MMU versions are
available to provide flexibility in enclosure mounting.
A module mounting unit is required to mount and provide
power to rack-mounted modules. The unit is for mounting
controllers, I/O modules, and communication interface mod-
ules. The MMU backplane connects and routes:
•
Controlway.
•
I/O expander bus.
