Let's see an
example
, for the programming of a simple traffic light, where the following
conditions are specified:
Values
≤250 Digits in Green
250<
Values
≤ 500 Digits in Yellow
Values
>500 Digits in Red
No delay times or hysteresis are established.
One of the possible parameter configurations would be the following:
Parameter
Value
B
00
C
250
D
00
E
500
nr
Green
r1
Yellow
r2
Yellow
r3

5.2.4 Status LEDs
For the debugging of problems in Profinet communication, the team has status indicators,
which signal problems with duplicate IPs, repeated DeviceNames, or problems in the ARs
between controller and networked devices.
the following table describes the meaning of the different leds
Values
≤250
250<Values
≤ 500
Values>500
Color (nr)
Color (r1)
Color (r3)
r1=r2=OFF
r1 =ON r2=OFF
r1=r2=ON
LED
MEANING
BF
(Bus failure)
ON:
The Ethernet connection is faulty; the IP address
is duplicated on the network; The DeviceName is
duplicated on the network; IP not defined
Flickering:
At least one configured AR is no longer in
the communication.
OFF:
There are no errors.
SF
(Group error)
ON:
At least there is an AR that is not in
communication.
OFF:
There are no mistakes.
