How to Access PLC’s Remotely for Support Purposes

More and more operations are requiring remote support for their programmable logic controllers (PLC’s) and associated peripherals like Human Machine Interfaces (HMI’s) and Operator Interfaces (OIT’s).   Trying to navigate your way through traditional approaches using router configurations or VPN’s  have been shown to be confusing, difficult, expensive to setup and maintain and can create unwanted cyber security vulnerabilities.

PLC Remote Access solves some of these problem in a unique, safe and simple way.  PLC Remote Access is a low hassle secure way to gain access to equipment in need of remote support.  Within a few minutes of receiving a call from a remote customer for the first time you can start accessing their equipment in the field.

PLC Remote Access gives access to programmable logic controllers (PLC’s) and associated peripherals like Human Machine Interfaces (HMI’s) and Operator Interfaces (OIT’s)   or other equipment that are located in locations remote to the person providing the support.  PLC Remote allows for remote access of equipment often without the need to reconfigure the existing network gateways or routers.  PLC remote access uses a secure encrypted method of communications.  We believe that the plcremote access method is more secure than a VPN because only one device at a time is accessed remotely.

  • plcremote can save making trips to the site where the equipment is located.
  • plcremote saves the cost of purchasing and installing a copy of PLC development / programming software at the remote site.
  • plcremote saves having to give customers a copy of the project source code (this can be a particularly big issue for Original Equipment Manufacturer’s – OEM’s ).
  • plcremote saves having to deal with IT to setup routers or VPN’s.
  • plcremote access requires no static IP addresses across the internet.
  • plcremote access requires no VPN’s.
  • Unlike VPN solutions, plcremote still works if you have duplicate subnet address ranges on the remote end
  • plcremote provide’s a secure connection method by using an encrypted connection.
