The Devices window displays the devices that are defined in the node. Runtime statistics will be maintained for each device that is in the Started state.

Displaying runtime statistics

To display the runtime statistics:

  1. Select a device in the list of devices.
    The device’s operational statistics are displayed in the Status tab.

  2. Select the Status tab. The following example displays the status panel associated with the GE Fanuc device.



Parameter

Value

Start Time (ms)

Millisecond length of time needed to start the device.

Stop Time (ms)

Millisecond length of time needed to stop the device.

Avg Queue Wait (ms)

Millisecond length of time device read/write requests spent in a queue waiting processing.

Queue Depth

Average number of items in the queue.

Last Read

Timestamp of the last read request.

Avg Read (ms)

Average Millisecond length of time needed to perform a device read.

Last Write

Timestamp of the last write request.

Avg Write (ms)

Average Millisecond length of time needed to perform a device write.

Last Occurrence

Most recent time the error occurred.

First Occurrence

Initial time the error occurred.

Variable

The Variable associated with the error occurrence.

Status

The error code that was encountered.

Ext. Status

An error code that was returned by the device.

Repeats

The number of times the error has occurred between the Last and First occurrence.

Displaying attributes

The GE Fanuc devices will display additional attributes when they are in the Started state. To display these attributes:

  1. Select a GE Fanuc device in the list of devices. The GE Fanuc device attributes are displayed in the Attributes tab.

  2. Select the Attributes tab.
    The Attributes tab for the GE Fanuc devices will display the attributes and their current values for the selected device:




Attribute

Value

Structure Count

The number of SINFO objects associated with the device. These are the registered structures, they may not all be in use.

Structure Member Count

The number of VINFO objects associated with all SINFO objects. This is the sum of all members attached to all structures.

Total Variable Count

The number of all VINFO objects associated with the device. If the VINFO is a structure, then also count the children, however counts arrays as individual items.

Variable Count

The number of VINFO objects associated with the device. These can be primitives, arrays or structures, but they only count as 1 item in the tree.
