Abstract
The disclosure relates to a method for configuring a control device of an automation system, comprising: detecting a local access token via an interface of the control device; and modifying at least one parameter of the control device, which is designed to configure a data connection of the control device in response to the detection of the local access token.
Claims13
A method for configuring a control device of an automation system, the control device being configured to operate at least one automation device of the automation system to perform a task, the method comprising:
- detecting a local access token via an interface of the control device;
- temporarily modifying, in response to detecting the local access token, at least one parameter of the control device that configures a data connection of the control device;
- and
- while the at least one parameter is modified, at least one of (i) configuring, using an external device, the control device via the data connection and (ii) performing, using the external device, a maintenance procedure on the control device via the data connection;
- and
- resetting the modified at least one parameter in response to one of (i) the local access token no longer being detected or (ii) a predetermined time period having elapsed since the at least one parameter was modified.
An automation system comprising:
- at least one automation device configured to perform a task;
- a control device configured to operate the at least one automation device to perform the task;
- an interface configured to detect a local access token;
- a configurable connection between the control device and at least one network;
- an access module connected to the interface and the control device, the access module being configured to (i) detect the local access token via the interface, (ii) temporarily modify, in response to detecting the local access token, at least one parameter of the control device that configures the configurable connection between the control device and the at least one network, and (iii) reset the modified at least one parameter in response to one of (i) the local access token is no longer being detected or (ii) a predetermined time period having elapsed since the at least one parameter was modified;
- and
- an external device configured to, while the at least one parameter is modified, at least one of (i) configure the control device via the data connection and (ii) perform a maintenance procedure on the control device via the data connection.
A processing unit for configuring a control device of an automation system, the control device being configured to operate at least one automation device of the automation system to perform a task, the processing unit configured to:
- detect a local access token via an interface of the control device;
- and
- temporarily modify, in response to detecting the local access token, at least one parameter of the control device that configures a data connection of the control device;
- and
- reset the modified at least one parameter in response to one of (i) the local access token is no longer being detected or (ii) a predetermined time period having elapsed since the at least one parameter was modified,
- wherein, while the at least one parameter is modified, an external device at least one of (i) configures the control device via the data connection and (ii) performs a maintenance procedure on the control device via the data connection.
