Methods, systems, and computer program products for communicating with a controller using a database interface |
摘要 |
Embodiments of the present invention provide methods, systems, and computer program products for communicating with a controller in real-time by storing a command for the controller in a database. The command may be a command to write a value of a real-time process control variable to the controller or a command to read a value of a real-time process control variable from the controller. Upon detecting the stored command in the database, the stored command is retrieved from the database and sent to the controller.
