摘要： Screen data created by an image processor (74) of a control host computer (7) is transmitted to a programmable display device (5). Based on the screen data, the programmable display device (5) queries a PLC (3) about the state of a device (21) to update display and transmit control instructions according to an input result. An applet that a compiler (76) produces by compiling the screen data is transmitted to a client device (9) through the Internet (32) by an open server (77) of the control host computer (7). The client device (9) executes the applet, sends the open server (77) an inquiry and control instructions similar to those from the programmable display device (5), and updates a display according to a response. A control system is realized for remotely checking the display contents of the programmable display device (5) without redrawing.

摘要： An indicator by which an abnormal state of equipment to be controlled can be confirmed. A process performed by a control part of the indicator which can reproduce a moving image includes a step (S602) wherein an input of an analog image signal is received, a step (S604) wherein the image signal is converted into a digital signal, a step (S606) wherein a time data is read out, a step (S608) wherein an image data relating the time data with the digital signal is generated , and a step (S610) wherein the image data is stored in an image data storing part.
