Introducing the IO Scanning Page

The IO Scanning page displays read-only data describing the current state of the processor in its role as I/O scanner.

Accessing the IO Scanning Page

Access the IO Scanning page from the Diagnostics menu. In the navigation menu at the left side of the page, select Diagnostics > Ethernet > IO Scanning.

IO Scanner Display

The top of the page displays the following general diagnostic information about the scanner:

• I/O Scanning status :

  • OK indicates that the values in the Scanned Device Status grid represent the state of scanned devices.

  • NOK indicates that the processor is not scanning. In this case, any data that appears in the grid is meaningless.

• Number of transactions per second

• Number of connections

In the Scanned Device Status grid, the colors that appear in each block indicate the following states for specific remote devices:

• GREEN indicates that a device is being scanned.

• BLACK indicates that I/O Scanning of the specific device has been intentionally disabled.

• GRAY indicates a device that is not configured.

• RED indicates a suspect device.

When you place your mouse pointer on a block representing a configured remote device, its IP address is displayed on the top left of the table. When you select a block representing a configured remote device, the home page of the device is displayed (if the device includes an embedded web server).
