Anybus CompactCom 40 - PROFINET IRT Transparent
Ethernet
Appendix F. AIDA LED Mode
The German car manufacturers have through the Automation Initiative of German Domestic Automobile
Manufacturers (AIDA) defined an AIDA specific LED behavior for PROFINET devices. It is necessary to implement
this behavior, to pass conformance tests for AIDA. Any application using the Anybus CompactCom 40 PROFINET
IRT can be designed to conform to the AIDA LED behavior standard.
1. How to Design for AIDA LED Mode
The default version of the Anybus CompactCom 40 PROFINET IRT has one LED for Network Status, one LED for
Module Status and one LED per port to indicate both link and activity. In the AIDA LED indication mode, one
LED indicates Bus Failure and one LED indicates System Failure, but link and activity for each port are shown
separately on different LEDs.
The front of the Anybus CompactCom 40 PROFINET IRT does not carry enough LEDs to show both the link and
the activity indications that are demanded in the AIDA LED mode, but the signals are available on the host
application connector.
To implement the AIDA LED Mode in an Anybus CompactCom 40 PROFINET IRT, do the following:
• Select LED indication mode by setting attribute #7 in the Application Object (FFh) to 1 (AIDA LED mode). This
will make the link and the activity signals separately available in the host application connector.
• In your hardware design, connect orange LEDs to the appropriate pins of the host application connector, to
indicate activity for each port.
IMPORTANT
The Port Activity and Port Link signals are available in the host application connector in all operating
modes except 16 bit parallel. The signals are always available in the LED status register, see Anybus
CompactCom 40 Software Design Guide for more information.
When Transparent Ethernet is activated, the LED status signals are only available in the LED status
register.
