HALL MONITOR SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve service without increasing hall personnels necessary by emitting abnormality notice signals from an abnormality detection means to communication slave machines, transmitting the abnormality notice signals to a programmable controller through communication master machines and displaying them on a screen display device. SOLUTION: Communication slave machines (b), (c), (d), (e) and (f) are connected to the communication master machine A, and the communication slave machines (h), (i), (j), (k) and (l) to the communication master machine G. The master machine A and the master machine G are connected to the programmable controller PC 2 as different systems by link wirings 3, and PC 2 and a color touch panel monitor 4 being the screen display device are connected by RS-232 C5. The communication master machines A and G collect the abnormality notice signals from the communication slave machines (b)-(f) and (h)-(l), arranges what kind of abnormality occurs in which part of which device or equipment, and transmits it to PC 2. PC 2 stores a monitor program, receives the abnormality notice signal and displays it on the screen of the color touch panel monitor 4.
