Fault diagnosis 

VISY-Input 8 has several LEDs which help in diagnosing problems. The positions of the LEDs 

can be found in the figure 1. 

4.1

 

Transmit LED TxD (8) / Receive LED RxD (9) 

The two red communication LEDs indicate, whether data are received or transmitted from 

VISY-Input 8. 

 

Under normal conditions, the communication LEDs should light up regularly. 

 

4.2

 

Input LEDs (10) 

The  eight  red  input  LEDs  indicate,  whether  an  input  is  activated  or  deactivated.  

The LEDs are assigned from left to right to the inputs 1 to 8. 

 

If an input is used as voltage input, the related input LED is on, when the 

voltage at the clamps"In" and "GND" is in the range of +5 V to +24 V.  

 

If an input is used as relay input, the related input LED is on, when the relay 

contact connected to the terminals "In" and "+12 V" is closed. 

 

4.3

 

Status LED (11) 

The yellow status LED indicates the status of the communication between interface card VI in 

the VISY-Command and VISY-Input 8. The following table lists the possible states of the sta-

tus LED and explains their meanings.
