Transformers may be fitted with turret tags suitable for soldering and printed circuit board assemblies may have solder pins.

You're permitted to use wiring channels if they're made of a flame-retardant insulating material. If you're working with back-connected control panels, you must provide access doors or swing out panels that swing about a vertical axis. Multiple-device control panels must have terminal blocks or attachment plugs and receptacles to terminate and connect all outgoing control conductors.

Figure 5 below shows a schematic diagram for a PLC based motor control system, similar to the previous motor control example.

The terminations of shielded or screened conductors should be terminated so that the screen cannot fray. If the screen is to be connected then make it off in the same way as for coaxial cable with a soldered pigtail and a sleeve.
By Annette Noele. Electrical Wiring. Published at Friday, February 02nd 2018, 03:36:21 AM. It is uncommon for engineers to build their own PLC panel designs (but not impossible of course). For example, once the electrical designs are complete, they must be built by an electrician. Therefore, it is your responsibility to effectively communicate your design intentions to the electricians through drawings.

By Linda Cerise. Electrical Wiring. Published at Thursday, February 01st 2018, 20:21:09 PM. Wiring diagrams show the connections to the controller. Wiring diagrams, sometimes called “main” or “construction” diagrams, show the actual connection points for the wires to the components and terminals of the controller.
By Severin Theodore. Electrical Wiring. Published at Thursday, February 01st 2018, 18:52:27 PM. Line diagrams, also called “schematic” or “elementary” diagrams, show the circuits which form the basic operation of the controller. They do not indicate the physical relationships of the various components in the controller. They are an ideal means for troubleshooting a circuit.

This is essential for industrial control systems that may contain hundreds or thousands of wires. These numbering schemes are often particular to each facility, but there are tools to help make wire labels that will appear in the final controls cabinet.
