1. A control and monitoring system, comprising:
- a processing unit that obtains an operating state signal from at least one monitoring target, detects a change in operating state of the monitoring target based on the operating state signal, creates a state change list in which the change in operating state of the monitoring target is listed in form of a text message including at least one of identification information for identifying the monitoring target and date-time information about date and time at which the change in operating state occurred in the monitoring target, as well as operating state information, and outputs a control signal to the monitoring target according to detected change in operating state; and
a human machine interface unit that includes an operation facility and a display unit that displays thereon the state change list, whereinwhen a message is selected from the state change list displayed on the display unit, the processing unit searches the state change list for a message that includes identification information included in the selected message, and displays a chart page that includes a timeline chart representing a temporal sequence of changes in operating state of the monitoring target identified in the selected message based on the selected message and searched message, whereinthe selected message includes a plurality of messages selected from the state change list displayed on the display unit, andthe processing unit displays a chart page that includes a plurality of timeline charts representing temporal sequences of changes in operating state of a plurality of monitoring targets identified in the selected messages, respectively.

Abstract
When a system operator selects a message to be analyzed from among a plurality of messages listed in a state change list displayed on an HMI unit, a monitoring target is identified from the selected message and all other messages that correspond to the same monitoring target are automatically searched. Subsequently, a timeline chart is displayed that represents changes in the operating state specified in the selected message and the found messages.
