Scanner Status

Introduction

The Scanner Status web page displays read-only data describing the current state of the BMX NOC 0401 Ethernet communication module in its role as I/O scanner.

Scanner Status Display

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

I/O scanning status
- A value of Operational indicates that the values in the Scanner Status grid are reporting the state of scanned devices.
- A value of Stopped indicates the local system is not scanning. In this case, any data that appears in the Scanner Status grid is meaningless.
Number of transactions per second
Number of connections

The Scanner Status web page looks like this:

In the Scanner 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 an device that is not configured
RED indicates a suspect device

NOTE: A green Scanner Status indicator in the grid can remain green for a remote scanned device after the Ethernet cable is detached from that device. This situation can occur if the health timeout value for that device is set to 0.

To avoid this result—and to help promote the accurate reporting of I/O scanning health—configure an operational health timeout value in the range 1...65535 (in 1 ms increments).

The grid also indicates the protocol used to communicate with the remote device:

MB: indicates a Modbus TCP connection
EIP: indicates an EtherNet/IP connection
