The PLC socket, useful but problematic
You may think that acquiring PLC devices that have a built-in electrical plug is a good idea. The truth is that it is useful, since you will be able to connect other devices. If, for example, you connect them in a room where you only have one plug, you would avoid being left without the option to connect another device.
But keep in mind that this can affect performance of PLC devices. It does not mean that they stop working, far from it, but it does mean that they may have problems offering maximum speed or that there is interference with Wi-Fi. Why is this happening? The Internet connection will travel through the electrical wiring and if we connect a computer, television or any device to that plug, it could generate noise that affects the connection.
You can especially notice this if you connect wirelessly and you are going to put some device nearby. You may find that coverage suffers and you may have trouble achieving maximum quality when wirelessly connecting devices to your PLCs. Coverage may decrease or speed may be lower.
Therefore, if you have a PLC model that has a built-in plug, our advice is to avoid connecting devices to it. Whenever possible, it should ideally be as far away as possible from other devices that could interfere and cause a malfunction.
Using rulers, a similar case
Another similar problem you may have is when using a power strip to connect the PLCs. In this case you are not connecting them directly to a plug to the electricity, but it goes through an intermediary that is the power strip. Again, here too you may run into issues and notice a loss of signal quality, speed, and limitations.
You will especially notice this if you connect other devices to the strip. For example if you plug in a computer, a television or anything. That is when you will notice more interference and the connection will start to work worse. The more things you connect near the PLCs, the worse they will work.
Ultimately, if you want the PLC work smoothly, without interruptions and with a good speed, it is not a good idea to use the integrated power connector, in case it has one. It is also not positive to connect it through a power strip. The ideal is to connect it directly to the wall and, in addition, that there are no other devices nearby that can interfere and cause a malfunction. The goal is to make the PLCs work as well as possible.
