State Information Handling In A Process Control System

A process control system comprising a state information handling serve including a processor configured to:

• obtain state information from user terminals of users in the process control system, the state information of at least two users including information about user operations in relation to objects in a process control flow screen,
• inspect the state information with regard to objects in the process control screen, which inspecting includes determining, for each user, if the corresponding user targets an object in the process control screen, and
• perform a user informing activity if objects in the process control screen that at least two users have targeted is the same or are linked.

A method for handling state information in a process control system, the method being performed by a state information handling server and comprising:

• obtaining state information from user terminals of users in the process control system, the state information of at least two users including information about user operations in relation to objects in a process control screen,
• inspecting the state information with regard to objects in the process control screen, which inspecting comprises determining, for each user, if the corresponding user targets an object in the process control screen, and
• performing a user informing activity if objects in the process control screen that at least two users have targeted is the same or are linked.

A computer program for handling state information in a process control system, the computer program comprising computer program code which when run in a processor of a state information handling server, causes the state information handling server to:

• obtain state information from user terminals of users in the process control system, the state information of at least two users including information about user operations in relation to objects in a process control screen,
• inspect the state information with regard to objects in the process control screen, which inspecting comprises determining, for each user, if the corresponding user targets an object in the process control screen, and
• perform a user informing activity if objects in the process control screen that at least two users have targeted is the same or are linked.

A computer program product for handling state information in a process control system, the computer program product comprising a data carrier with computer program code, which when run in a processor of a state information handing server, causes the state information handling server to:

• obtain state information from user terminals of users in the process control system, the state information of at least two users including information about user operations in relation to objects in a process control screen,
• inspect the state information with regard to objects in the process control screen, which inspecting comprises determining, for each user, if the corresponding user targets an object in the process control screen, and
• perform a user informing activity if objects in the process control screen that at least two users have targeted is the same or are linked.
