PROCESS DATA COMMUNICATION DEVICE, PROCESS DATA COMMUNICATION SYSTEM AND PROCESS DATA COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a process data communication device capable of transmitting process data without requiring setting to be particularly changed in a process monitoring control system even if a process data item is added/changed/deleted.

SOLUTION: A process data communication device 10 is connected to a process data collection device 12 for collecting process data 11 to be used in a plant monitoring control system via a process data network 13 and is connected to a data transmission line 40 for transmitting the process data 11 to a separate plant monitoring control system 24. The process data communication device 10 includes a process data network reception processing section 10a for receiving the process data 11 from the process data collection device 12 via the process data network 13 and a process data LAN transmission processing section 10b for transmitting the received process data 11 via the data transmission line 40.
