McMaster University

McMaster University was sponsored by eWON in the scope of the educational program ‘eWON on Campus’

Many engineering programs minimize the laboratories because of time, cost and space limitations. In W. Booth School of Engineering Practice and Technology of the Faculty of Engineering at McMaster University, we are addressing this issue by developing a series of industrial automation laboratories that are accessible onsite and online through the Internet. We call these labs ‘McMaster Internet Labs’, or ‘MiLabs’.

PLC laboratory set up

The laboratory setup has a PLC that controls a three-phase motor through a Variable Frequency Drive (VFD). In addition, the PLC’s analog inputs are connected to a vibration sensor and a temperature sensor through signal conditioners; and one of its outputs controls a lamp through a high voltage relay.


Remote Access to PLC laboratory equipment based on VPN

Mc Master Internet

The first version of these labs is based on Virtual Private Network (VPN). Therefore, users need to be authenticated using the university databases. The VPN sets up a virtual LAN, which is separate from the lab LAN and indeed the other university LANs. Since most PLC programming applications either do not have data routing capabilities or use serial connection, we use a virtualization lab server to provide Graphic User Interfaces (GUIs) for the lab controllers; host lab software such as Rslogix5000, Cx-Programmer, and RsWorx; and provide other services such as logon and service brokerage.


Remote Access to PLC laboratory equipment based on eWON

McMaster University was sponsored with two eWON routers (eWON Flexy and eWON Cosy) in the scope of the educational program ‘eWON on Campus’. The routers simplified our lab setup, and most importantly removed the need for users to be authenticated using the university databases. In fact using the VPN met that only McMaster students could use our labs, yet we have plans to share the labs with other institutions.

The other challenge we face with the lab VPN is that all equipment (PLCs, VFDs, Remote IOs, energy meters, and motor protection relays) have to be connected to the LAN that is managed by the university IT department. Since, at the lab level, we do not have administrative rights to create subnetworks, it is impossible to isolate the networks of individual lab setups. Using eWON solves this problem easily since each eWON creates its own LAN which you can configure to communicate or not communicate with other LANs in the laboratory.
