I'm sorry if I'm wrong because I'm not an expert in PLCs, but as I understand the memory bits of a PLC simulate physical switches and push buttons. By their nature, the bits are in state (0), which is why a MAKE command coincides with a switch that changes from an open state (0) to (1) when the switch is pressed by user, but this does not happen with a BREAK command that in order to is valid, the PLC memory bit which, as we said, is in a normal state (0) should become (1), that is why the electrical continuity of the circuit does not coincide with the logic BREAK command of the PLC, which in order to be valid, the memory bit must from (0) to (1) when the user presses the switch. I hope I didn't make the situation worse.
