This is an example of what I'm talking about:
https://www.automationdirect.com/ad...i-port_distribution_blocks/8000-88590-0000000
What do people usually use this for? Like which protocols? Profibus? Modbus? DeviceNet?
They often have M12 connectors that are A-coded or B-coded that have 4 pole or 5 pole.
A lot of times if it's 5 pole you'll find that pin 1 is supposed to be V+, pin 2 is N.C., and pin 3 is supposed to be V-.
Why would they specify that on there? What standard are they adhering to, if any?
