With Ethernet now well and truly established in the industrial control space it is often the go to for connecting to the devices as it removes the need to carry around a proprietary cable for every device. So, to help reduce the cables by one more this tech tip will walk through the basics of connecting to Schmersal’s PSC1 via ethernet using SafePLC.
This Tech Tip is a follow on from parts 1 and 2 of previous titles ‘Connect Via Modbus with Red Lion and ABB’, and ‘Connect via Modbus – Part 2’.

Harmonics in electrical systems can be considered as pollution of the electrical grids and can have negative effects on plant equipment. Harmonic frequencies in the power grid are a frequent cause of power quality problems including increased heating in equipment and conductors, misfiring in variable speed drives, and torque pulsations in motors. The results can be unpredictable legal and financial ramifications.
