PLC remote access with FlexiHub

Last updated

Connecting to a PLC remotely

Programmable logic controllers are used along with other devices like operator interfaces (OITs) and human-machine interfaces (HMIs) in many Internet of Things (IoT) and industrial automation implementations. It is often beneficial to establish remote access to PLCs, but traditional methods of doing so present several issues. These solutions can be expensive, complex, and may introduce additional security weaknesses to an infrastructure.

PLC Remote Access addresses and solves these connectivity issues by providing a simple and secure method of connecting to a controller remotely. The tool offers a streamlined method of managing a PLC with remote access and can quickly be configured to communicate with equipment in the field. It’s a great solution for establishing remote access PLC support from any network-connected location.

This software tool gives remote access to PLCs and associated peripherals to support personnel located anywhere in the world. There are no requirements to reconfigure network settings or hardware. All data transfer is conducted using encryption to ensure secure communication.

Remotely configure PLCs and other equipment

Communication between a PLC and a computer is usually done using serial interfaces such as USB, RS-232, RS-422, or RS-485 and Ethernet protocols. The software required to interact with PLCs is accessed over a network connection. A PLC Internet connection enables a centralized server to communicate with any devices attached to the same network.

Remote PLC software virtualizes your computer’s serial connections and enables you to access serial-based devices attached to your network. It eliminates the need for a physical connection between the server and the equipment you wish to access and control.
