<p>PURPOSE: To enable an operator to grasp the operation state of an operation terminal where operation output is performed by storing an operation terminal in-process data storage means with operation states of operation output by operation terminals, and taking the operation states of operation terminals out of the operation terminal in-process data storage means and displays them on a display device. CONSTITUTION: A plant equipment operation means 25 when taking input/output information out of a plant equipment information storage means 2 at an operation request and performing operation output stores the operation terminal in-process data storage means 21 with the operation state of the operation output by operation terminals. Then a plant equipment operation in-process processing means 26 takes out the operation state of the operation terminal which performs the operation output out of the operation terminal in-process data storage means 21 and displays it on the display device. Consequently, the operator can grasps the operation state of the operation terminal and reduces the burden on the operator.</p> |
