Use the OPC UA Diagnostics web page to view dynamic data describing the operation of the OPC UA server embedded in the BMENUA0100 module.

NOTE: The OPC UA Diagnostic web page is refreshed every 5 seconds.

Diagnostic Data

OPC UA Diagnostics web page displays the following read-only data. Note that all numeric values are in decimal format:

Field

Description

PLC Diagnostic

EPAC

CPU IP address.

Device Identity

CPU part number.

Device Version

CPU firmware version.

Device Status

Connection status with CPU: Good, Bad, Uncertain, Unknown, Missing.

Frame Time Out (in ms)

The maximum length of time the OPC UA server will wait for an answer from a device after sending a request. For example, 1000.

Maximum Channel number

Number of connections opened by OPC UA server on the CPU.

Channels used for non-Timestamping

Number of connections that carry application data.

Channels used for Timestamping

Number of connections that carry timestamping data.

Request Length

Length of request for communication with CPU.

Application Name (Device)

Control Expert project name.

Application Version (Device)

Application checksum and signatures.

Preload data dictionary

Available or Unavailable for application in PAC.

Timestamping Status

Timestamping status is displayed:

  • Timestamping is enabled with access to Timestamped Variables in application.

  • Timestamping is NOT enabled, NO access to Timestamped Variables.

List of devices with source time stamping configured

If timestamping is enabled, a list of devices is displayed indicating for each device:

  • Number of dedicated channels reserved for Timestamp Event Source polling.

  • Device type (CRA, CPU, etc.).

  • IPv4 address.

  • Reservation of device timestamp buffer by the BMENUA0100 OPC UA embedded server: true / false.

OPC UA Diagnostic

Endpoint url (IPV4)

OPC UA server IPv4 address, in the format: “opc.tcp://<IPv4 address>:<port number>”. For example: opc.tcp://192.168.2.142:4840

Fast Sampling Rate

Indicates if the Fast sampling rate setting is selected:

  • True = selected

  • False = not selected

Number of connected sessions

Total number of client sessions supported by the BMENUA0100 embedded OPC UA server.

Subscription(s) Information:

Information describing the variables monitored by the OPC UA server that are included in one or more subscriptions.

Number of monitored item(s) from internal Server node:

Number of specific monitored item(s):

Number of non specific monitored item(s):

Number of TimeStamped monitored item(s) with monitoring mode not disabled:

Total Number of monitored item(s):

Current number of timers

The number of configured sampling intervals for the BMENUA0100 embedded OPC UA server:

Timer list

A list describing each sampling interval (i.e., timer) monitored by the BMENUA0100 embedded OPC UA server. Each item indicates:

  • The sampling interval in ms.

  • The number of monitored items.

  • The number of requests generated during the most recent execution.
