<p>PURPOSE:To prevent the operation from becoming impossible caused by the increase in cost and system down due to the lowering of processing speed by the communication of a bus and the piling of hardwares. CONSTITUTION:The information collection processing part 55 of a monitoring device 30 performs the input/output with a sequence controller 10 by a sequence controller interface means 55a and the input/output with a single loop controller 20 by a single loop controller interface means 55b, and performs a collection processing of information to be displayed on a CRT 70 and information to be printed and outputted by a slip printer 80 and an annoucement printer 90. Because an information collection part and an information processing part are not separately provided in a conventional way, the operation impossible due to the lowering of processing speed by the communication of a bus, the increase in cost and system down can be prevented. Therefore, the operation state of a plant can be exactly monitored and operated.</p> |
