AI Technical Summary

Technical Problem

Existing telemetry devices using modular PLCs cannot facilitate mutual communication between modules that are not directly connected, preventing operators from confirming the execution of instructions across the network.

Method used

A communication system where a telemetry device is connected via a first network, incorporating a telemetry module that controls communication between multiple networks, allowing modules to transmit and receive data using a unified communication protocol via a second network, enabling communication with devices connected via a wide area network.

Benefits of technology

Enables modular PLCs to communicate with devices across a network, simplifying network design and allowing remote monitoring and control of multiple modules through a unified protocol, enhancing operational efficiency.

Abstract

To provide a communication system in which a module type PLC included in a telemeter device and equipment network-connected to the telemeter device can communicate with each other.SOLUTION: A telemeter device 1 and an apparatus 13,14 are connected via a first network 24. A telemeter device 1 includes a processor for processing data recorded in a memory 19, a telemeter module 20 for controlling communication between a first network 24 and a second network 23, and a first module 5,10 connected to the telemeter module 20 via the second network 23 and connected to the memory via a third network 35. The first module 5,10 transmits and receives data transmitted and received between the device 13,14 and the memory via the first network 24, the telemetry module 20, and the second network 23 in accordance with the first communication protocol used for communication with the device 13,14.SELECTED DRAWING: Figure 2
