The STB NIB 1010 Basic NIM Module

LED Physical Description

Overview

The six LEDs implemented in the STB NIB 1010 INTERBUS NIM are visual

 

indications of the operating status of the island bus on an INTERBUS network. The

 

LED array is located at the top of the NIM front bezel.

General

The bottom three LEDs indicate the status of data exchange between the

Indications

INTERBUS fieldbus master and the Advantys island bus:

 

LED 4—RC (remote bus check)

 

LED 5—BA (bus active)

 

LED 6—RD (remote bus disabled)

 

The top three LEDs indicate activity or events on the NIM:

 

LED 1—RUN

 

LED 2—PWR/UL

 

LED 3—ERR

 

The following tables describe the LED behavior in more detail. When you refer to

 

these tables, keep in mind:

 

It is assumed that the PWR/UL LED is on continuously, indicating that the NIM is

 

receiving adequate power. If the PWR/UL LED is off, logic power to the NIM is off

 

￿or insufficient.

 

Individual blinks are approximately 200 ms. There is a 1-second interval between

 

blink sequences. For example:

 

blinking—blinks steadily, alternating between 200 ms on and 200 ms off

 

blink 1—blinks once (200 ms), then 1 second off

 

￿blink 2—blinks twice (200 ms on, 200 ms off, 200 ms on), then 1 second off

 

blink n—blinks n (some number) times, then 1 second off
