Xinje XDPPro / XINJEStudio for Pump Control

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...

Common Mistakes to Avoid:

Counting level instead of edge - multiple counts from one event

Not debouncing noisy inputs causing false counts

Using standard counters for high-speed applications

Integer overflow causing count wrap-around

Typical Applications:

2. Flow meters (magnetic, ultrasonic, or vortex): Critical for monitoring system state
3. Level transmitters for tank or wet well level: Critical for monitoring system state
4. Temperature sensors for bearing and motor monitoring: Critical for monitoring system state
5. Vibration sensors for predictive maintenance: Critical for monitoring system state

Output Devices (Actuators):
