Introduction

Refer to the LED indicators to monitor the status and performance of these items:

Module LED Descriptions

The module LED indicators are located on the front of the BMENOR2200H module. The LEDs provide information on:

  • module status (run, error, downloading)

  • Ethernet network communications

  • RTU communications

  • SD memory card state

  • serial communications

  • cyber security mode

This is the LED display on the front of the BMENOR2200H module:

The LEDs can be in these states:

  • on: steady on

  • off: steady off

  • flashing: alternate (250 ms on, 250 ms off)

The module status is indicated by the color and state of the LEDs:

Label

Color

Pattern

Indication

RUN: operational state

green

on

The module is operating and configured.

flashing

The module is blocked by a detected software error.

off

The module is not configured. (The application is absent, invalid, or incompatible.)

ERR: detected error

red

on

  • The processor, system, or configuration detected an error.

  • If you move the rotary switch from Standard > Advanced (or vice versa) directly instead of moving to Cybersecurity Reset in between, an error is detected: Missing Cybersecurity Reset

flashing

  • The module is not configured. (The application is absent, invalid, or incompatible.)

  • The module is blocked by a detected software error.

  • A Hot Standby problem is detected.

off

Operations are normal (no detected errors).

DL: download firmware (upgrade)

red

on

A firmware upgrade or factory reset is in progress.

off

A firmware upgrade or factory reset is not in progress.

NS: control port status

green

on

One of the two control ports is enabled and linked successfully.

red

on

There is duplicated IP on the backplane Ethernet port or the factory reset mode.

—

off

There is no link on the two control ports.

RTUCNX: RTU connection status

green

on

At least one RTU connection (Client or Server) established in the module.

flashing

There is no RTU connection. 

BS: backplane Ethernet port status

green

on

Link is successfully connected on the backplane Ethernet port.

red

on

There is duplicated IP on the backplane Ethernet port or the factory reset mode.

CARD ERR: memory card detected error

red

on

  • The data logging service is enabled, but the memory card is missing.

  • The data logging service is enabled, but the memory card is not usable (for example, bad format, unrecognized type, etc.).

off

The memory card is valid and recognized.

SER COM: serial data status

yellow

flashing

A data exchange (send/receive) is in progress on the serial connection.

off

There is no data exchange on the serial connection.

SEC: communication security status

green

on

The selected communication security level is enabled and running fine.

red

on

  • Communications are not secure because a critical error in communication security is detected. For example, there is no available security configuration, or the certificate expired when the communications stopped.

  • No channel security is configured through the channel name for either client or server.

flashing

The selected communication security level is enabled and running, but a critical error is detected. For example, there is no available security configuration, or the certificate expired when the communications stopped.

—

off

The cybersecurity function is not enabled.

Typical Status and Related LED Behavior

Label

Indication

ERR

Red on

Missing Cybersecurity Reset: The rotary switch was moved directly between Standard mode and Advanced mode. A factory reset is required before switch to alternative mode.

Description

Factory mode

RUN: green on

 –

DL: red on

DL: red off

Factory reset is ongoing.

Factory reset is complete.

BS: red on

NS: red on

 –

Initial cybersecurity mode (first-time start up without valid cybersecurity setting)

ERR: red flashing

Module is not running; a validated cybersecure setting is required.

BS: green flashing

SEC: red on

LEDs on Control Ports

There are two LEDs on each RJ45 port. One is ACT (Active) and another is LNK (Link). The two LEDs can be used to diagnose the state of Ethernet communications over the control ports:

  • The ACT LED indicates the presence of Ethernet activity on the port.

  • The LNK LED indicates the existence of an Ethernet link and the link speed.

LED

State

Description

ACT

green

Link established, no activity.

green flashing

Link established, activity detected.

off

No link established.

LNK

green

Link established at speed equal to module maximum capability (1000Mbps).

yellow

Link established at speed less than module maximum capability (10/100Mbps).

off

No link established.
