Xinje XDPPro / XINJEStudio for Sensor Integration
Xinje XDPPro is the free Windows-based IDE for the XD/XL/XC/XLH PLC families. Its instruction set borrows heavily from Mitsubishi FX conventions — engineers familiar with GX Works2 will recognise contact, coil, MOV, ADD, and pulse-output mnemonics almost one-for-one — which is deliberate, since XDPPro positions itself as a low-cost migration path away from FX. The IDE includes a built-in offline simulator, ladder-logic monitoring, sequence-function-chart editing, and a basic instruction-list edi...
