Channel0x Diagnostics dialog box

How do I open the Channel0x Diagnostics dialog box?
  1. Diagnostics
     is disabled when:
    • You are operating offline.
    • An identity mismatch exists.
    In the
    Controller Organizer
    , expand the
    I/O Configuration
     folder, and double-click the module.
  2. In the
    Module Properties
     dialog box, expand
    Channels
    .
  3. Click a
    Ch0x
    , and then click
    Diagnostics
    .
The
Channel0x Diagnostics
dialog box includes these parameters:
Parameter
Description
Value
Fault Exists
Shows whether a fault is present on the module.
None
Present
Data Uncertain
Shows the module is operating outside the designed operating range, or data is under manual or override control.
No
Yes
Field Power
Shows whether field power is present on the channel.
Not present
Present
Short Circuit Fault
Shows whether a short circuit or over-current fault (greater current at an output than the maximum current level the channel can handle) is present on the channel.
None
Present
No Load Fault
Shows whether a no load fault (a signal wire is disconnected from the output or the RTB is removed from the module) is present on the channel.
None
Present
Open Wire Fault
Shows whether an open wire fault (an output wire is disconnected) is present on the channel.
None
Present
Fault Timestamp (Short Circuit, No Load, Open Wire, Over Temperature Last Fault)
Shows the timestamp of the fault in YYYY-MM-DD-HH:mm:SS.mmm format.
  • YYYY = year
  • MM = month
  • DD = day
  • HH = hour (24 hour)
  • mm = minutes
  • SS = seconds
  • mmm = milliseconds
A valid time or
None
 if there is no recorded event time.
Module Over Temperature Fault
Shows whether the module is operating at a higher temperature than its operating limits.
None
Present
Range
Shows the range for the most recently calibrated channel.
-10 V to 10 V
0 V to 5 V
0 V to 10 V
1 V to 5 V
0 mA to 20 mA
4 mA to 20 mA
-100 mV to 100 mV
1 Ohm to 500 Ohm
2 Ohm to 1000 Ohm
4 Ohm to 2000 Ohm
8 Ohm to 4000 Ohm
Gain
Shows the channel calibration gain from the last valid calibration.
32-bit floating point value
Offset
Shows the channel calibration offset from the last valid calibration.
32-bit floating point value
Refresh communications
Updates the data displayed on the dialog box.
