Abstract

An electronics module configured for insertion into a carrier unit and having, arranged on a rear side, a coding pair including a first coding part and a second coding part, wherein the first and second coding parts are configured in accordance with the lock-and-key principle, the first coding part being snapped into place in the rear side, while the second coding part is removably arranged on the first coding part, wherein a plug-and-socket connector is arranged on the second coding part such that a mating plug-and-socket connector arranged in the interior of the electronics module is insertable into the plug and-socket connector to establish an electrical connection, and wherein a memory chip which is connected to the plug and socket connector is also arranged on the second coding part.

First claim

What is claimed is:

1. An electronics module configured for insertion into a carrier unit and having, arranged on a rear side, a coding pair, comprising:
a first coding part;
an octagonally shaped second coding part including a plurality of latching lugs arranged on outer edges of the octagonally shaped second coding part and coding teeth arranged on a cylinder extending from a rear of the octagonally shaped second coding part, the first coding part and the octagonally shaped second coding part being configured in accordance with a lock-and-key principle, the first coding part being arranged to snap into place in the rear side, and the octagonally shaped second coding part being removably arranged on the first coding part;
a mating plug-and-socket connector arranged on a printed circuit board assembly within an interior of the electronics module;
a plug-and-socket connector mounted on a further printed circuit board and arranged within the octagonally shaped second coding part such that the mating plug-and-socket connector is insertable into the plug-and-socket connector to establish an electrical connection; and
a memory chip configured to hold unique address data for a failsafe automation system, said memory chip being arranged on the further printed circuit board of the plug-and-socket connector and arranged on the octagonally shaped second coding part.

2. The electronics module as claimed in claim 1 , wherein the first coding part is configured to snap into place in different positions in the rear side and to provide a plurality of coding possibilities.

3. The electronics module as claimed in claim 1 , wherein the coding pair is configured such that when the electronics module is initially inserted into the carrier unit, the octagonally shaped second coding part snaps into place in the carrier unit and remains captive in the carrier unit.

4. The electronics module as claimed in claim 2 , wherein the coding pair is configured such that when the electronics module is initially inserted into the carrier unit, the octagonally shaped second coding part snaps into place in the carrier unit and remains captive in the carrier unit.

5. The electronics module as claimed in claim 1 , wherein the memory chip is configured to save data in an event of a failure of the electronics module.

6. The electronics module as claimed in claim 1 , wherein the plug-and-socket connector comprises a coaxial connector.

7. The electronics module as claimed in claim 6 , wherein the coaxial connector is configured such that a retaining force between the plug-and-socket connector and the mating plug-and-socket connector ensures that the octagonally shaped second coding part remains attached to the electronics module until the electronics module, after having been inserted into the carrier unit, is once more withdrawn.

8. The electronics module as claimed in claim 5 , further comprising:
a data evaluator for evaluating the data on the memory chip.

9. The electronics module as claimed in claim 8 , further comprising:
an inhibitor for comparing setpoint values with actual values and for one of activating and deactivating the electronics module as a function of a comparison result, the inhibitor being connected to the data evaluator for evaluating the data on the memory chip.
