Abstract
The object is to provide a method for operating and/or observing at least one field device in the simplest possible manner. A first central control device which executes the automation engineering software generates a first command to control the at least one field device and transmits the first command to the at least one field device. At least a second central control device which executes the automation engineering software generates a similar second command for controlling the at least one field device and transmits the second command to the at least one field device. The at least one field device receives the transmitted first and second commands and executes at least one of the received commands. An automation system for carrying out the method is also provided.
Claims14
A method of operating and/or observing at least one field device, the method which comprises:
- producing a first command, with a first central control device implementing automation software, for controlling the at least one field device and transmitting the first command to the at least one field device;
- producing a second command, similar to the first command, for controlling the at least one field device with at least one further central control device implementing the automation software and transmitting the second command to the at least one field device;
- and
- receiving the first and second commands with the at least one field device and implementing only that command of the mutually similar first and second commands received first by the at least one field device.
An automation system for operating and/or observing at least one field device, comprising:
- at least two central control devices configured to implement the same automation software;
- at least one field device connected to said central control devices through a data link and receiving mutually similar first and second commands produced by said central control devices;
- and
- a command identification device associated with said at least one field device and allowing implementation of only that command of the first and second commands that is received first.
