Diagnostics
The most frequent faults arise in conjunction with other devices or components. Therefore,
when a fault occurs the Inline controller should not be isolated straightaway; instead, it
should be viewed as part of the system as a whole.
Various tools are available for fault localization; these are explained in
and status indicators” on page 10
:
–
Supply LEDs
–
Process status LEDs
–
I/O status LED
–
Communication LEDs
–
Service LED
–
Ethernet status LEDs
Niagara also features wide-ranging diagnostic tools for analyzing communication in con-
nected automation networks.
Before carrying out a detailed analysis of any fault, make sure that the device is properly
wired, is being supplied with power, and has booted up. Pay particular attention to the fol-
lowing:
–
All spring terminals and snap-in latches are properly engaged.
–
The DIN rail is correctly grounded.
–
The functional ground connection of the Inline controller is connected to the DIN rail via
a 1.5 mm² conductor with a grounding terminal.
–
The UM, US, and UL LEDs are permanently lit.
–
The supply voltage is within the specified tolerances (see also
and
The process status LEDs provide a reliable indication of the operating state (see
“Diagnostic and status indicators” on page 10
). The boot process is only complete when
these flash steadily with a brief light-up duration.
