Indicators on VersaPoint Modular IO terminals
8.1.1
Indicators on NIU / Network adapters and terminals with
remote bus branch
Important
For the meaning of the diagnostic and status indicators of the NIU / Network adapter and
the terminals with remote bus branch, please refer to the corresponding documentation.
8.1.2
Indicators available on different terminals in the
VersaPoint system
Some indicators can be found on various terminals (see section below) and generally have
the same meaning:
Diagnostic and status indicators
Diagnostic and status indicators
The diagnostic indicators (red, yellow or green) provide information
about the state of the device and, in the event of an error, provide
information about the type and location of the error. The device is
operating correctly if all of its green LEDs are on.
The status indicators (yellow) indicate the status of the relevant
input/output and the connected I/O device.
Some devices have extended diagnostics. A short circuit or overload of
the sensor supply is indicated for each input. If a short circuit occurs at
an output, each channel is diagnosed individually. Information about
the supply voltage is also reported. Information about peripheral
faults is sent to the control system with precise details of the error
type and is displayed using status indicators.
Important
For information about the diagnostic and status indicators on a
specific device, please refer to the device-specific data sheet.
