摘要

PROBLEM TO BE SOLVED: To provide a data collection system, a data collection method, a PLC data transmission device, a data collection device, a PLC data transmission program, and a data collection program capable of collecting various data.;SOLUTION: A PLC data transmission device 4 acquires data from a PLC(Programmable Logic Controller) 5, and converts the acquired data into an MQTT(Message Queue Telemetry Transport) message, and transmits the MQTT message to an MQTT server device 3. The MQTT server device 3 receives an MQTT message from the PLC data transmission device 4, and receives an MQTT message from MQTT equipment 7, and transmits the received MQTT message to an SCADA(Supervisory Control And Data Acquisition) server device 1. The SCADA server device 1 receives the MQTT message from the MQTT server device 3, and converts the received MQTT message into data in a predetermined format suitable for storage in a database 2, and stores the converted data in the database 2.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
