Device Diagnostics parameters

The
Device diagnostics
 dialog box is used for multiple device types so the parameters displayed can vary. Settings that do not apply to a device type do not appear.
TIP:
When the connection is lost to the device, a timeout error occurs. On dismissal of the error message, the parameters are blank.

HMI packet rate
Shows the rate at which the HMI packets are being sent and received.
The number of Class 3 packets and unconnected packets sent and received by the device in the previous second.
The available values range from 0 to 2147483647.
IO packet rate
Shows the rate at which the I/O data is being sent and received.
The number of Class 0 and Class 1 packets that were sent or received by the adapter in the previous second.
The available values range from 0 to 2147483647.
EtherNet errors
Shows the sum over all ports of the following EtherNet Link object values: In Discards, In Errors, In Unknown Protos, Out Discards, Out Errors, Alignment Errors, FCS Errors, Single Collisions, Multiple Collisions, SQE Test Errors, Deferred Transmissions, Late Collisions, Excessive Collisions, MAC Transmit Errors, Carrier Sense Errors, Frame Too Long, and MAC Receive Errors.
The available values range from 0 to 2147483647.
Flash update required
Shows whether the device requires application firmware.
The available values are:
  • True
    . Device has no application firmware. This can occur if the firmware update process is interrupted, or the device shipped without the application firmware.
  • False
    . Device has application firmware
Network status
Shows the current status of the network.
Supervisor status
Shows the current status of the supervisor.
Time Synchronization Status
Shows whether the device is currently synchronized with a Precision Time Protocol (PTP).
The available values are:
  • Synchronized
  • Not Synchronized
Grand master clock identity
Shows the identity of the Grand Master clock to which the device is synced.
The valid value is an 8‑byte hex number.
Local clock offset to system time
Shows the offset, in nanoseconds, from the local clock to the system time.
Use this value to detect steps in time. This value updates when a PTP update message is received.
The available values range from -9223372036854775808 to 9223372036854775807.
Local clock offset timestamp
Shows the timestamp of the local clock offset in YYYY-MM-DD-HH:mm:SS_mmm_uuu_nnn (UTC-00:00) format.
  • YYYY = year
  • MM = month
  • DD = day
  • HH = hour (24 hour)
  • mm = minutes
  • SS = seconds
  • mmm = milliseconds
  • uuu = microseconds
  • nnn = nanoseconds
  • UTC-00:00 = Time zone
Possible values are a valid time or
None
 if there is no recorded event time.
Over temperature
Shows whether the device is at a normal or higher temperature than its rated operating limits.
The available values are:
  • Yes
    . Device is at a higher temperature than its rated operating limits
  • No
    . Device is at a temperature within its rated operating limits
Over temperature timestamp
The time when an over temperature condition was most recently detected.
Possible values are a valid time or
None
 if there is no recorded event time.
Critical temperature
Shows whether the temperature is above or below the critical temperature limit for proper operation.
The available values are:
  • Yes
    . Device is above critical temperature limit for proper operation and may shutdown without further warning
  • No
    . Device is not above critical temperature limit for proper operation
Critical temperature timestamp
The time when a critical temperature condition was most recently detected.
Possible values are a valid time or
None
 if there is no recorded event time.
Low system power alarm

    . Power voltage is not below configured Low System Power Limit
Low system power timestamp
The time when a Low System Power condition most recently transitioned from No to Yes.
Possible values are a valid time or
None
 if there is no recorded event time.
High system power alarm
Shows whether the input system power voltage moves above the configured High System Power Limit.
If it is above the configured High System Power Limit, it remains set until the input system power voltage moves below the configured High System Power Alarm Limit.
