Status display of the EM 141 DI 8
DC 24V DIAG (6ES7 141-1BF30-0AB0)
In the case of the expansion module there is 1 LED (with two colors) for each
channel (X1 to X4) for status display:
Green/red LED
The LED is green when the input is active.
The LED is red when there is a fault on the channel:
– Short circuit of the 24 V sensor power supply
– Digital input wire break
24 VDC LED
The power module also has a 24 VDC LED. The 24 VDC LED is on when the
power module is connected to a load-voltage supply.
If no load voltage is available:
the SF LED on the power module is on
the 24 VDC LED on the power module is off
5.3.4
LEDs on EM 143-DESINA expansion modules
Status display
The ET 200X-DESINA has two LEDs per channel (X1 to X8) 2 LEDs for status
indication:
”Yellow” LED (for digital input or output, pin 4)
The LED is yellow when the input or output is active.
Red/yellow LED (for pin 2 input functionality, see Table 5-1)
The LED is red when
– the functional input is parameterized as a diagnostics input for DESINA and
– a DESINA fault (status ”0”) is registered for the sensor/actuator.
The LED is yellow when
– the functional input is parameterized as an input with NC function and
– the status of the sensor connected to the input is non-switched (”1”).
