PNP vs NPN Sensor Wiring to a PLC, Explained on Video
A PNP sensor switches +24 V and needs a sinking input; an NPN sensor switches 0 V and needs a sourcing input. Wiring for S7-1200 1M, Mitsubishi FX and Delta S/S, plus a meter test.
TIA Portal First Project: Step-by-Step Video Walkthrough
Create a TIA Portal project, add an S7-1214C, set its IP, write a start/stop rung in OB1, compile with zero errors and archive it. A written walkthrough beside ControlByte's video.
XIC, XIO and OTE in Studio 5000: A Video Walkthrough
XIC is true when a bit is 1, XIO is true when a bit is 0, and OTE writes the rung result to a bit every scan. A Studio 5000 walkthrough with a truth table and the NC stop button trap.
Modbus RTU Explained: Registers, Addresses, Frames, CRC
Modbus RTU: one master polls up to 247 slaves over RS-485 using four data tables. Why 40001 means offset 0 on the wire, how a frame and its CRC are built, and how to read a 32-bit value.
