I/O Wiring¶

Digital InputsDigital OutputsAnalog Inputs

Sensor COM  ──→  DI Common (0V)
Sensor NO   ──→  DI0 … DI13

All digital inputs are optically isolated. Pull-up resistors are built in.

Load (+)  ──→  DO0 Common
Load (-)  ──→  DO0 … DO9

Relay ratings

Max 5A per relay output. Use external contactors for motors and large loads.

Sensor signal  ──→  AI0 … AI3
Sensor GND     ──→  AI GND

Select 0–10V or 4–20mA via DIP switch SW1–SW4 on the module.

Programming¶

ElephantPLC X1 supports all IEC 61131-3 languages:

Language	Best for
Ladder Diagram (LD)	Simple relay-logic replacements
Structured Text (ST)	Mathematical calculations, loops
Function Block Diagram (FBD)	Signal processing, PID loops
Sequential Function Chart (SFC)	State machines, step sequences

Install ElephantStudio IDE¶

# Windows installer

Upload your first program¶

Open ElephantStudio → New Project → select X1
Write your ladder logic in the Main POU
Go to Online → Connect (enter PLC IP: 192.168.1.100)
Click Download then Run

Modbus¶

Modbus RTU (RS485)¶

Configure in: System Settings → Communication → COM1

Baud Rate:    9600 (default)
Data Bits:    8
Parity:       None
Stop Bits:    1
Device ID:    1 (adjustable 1–247)

Modbus TCP¶

The PLC listens on port 502 by default. Register map:

Address	Type	Description
`0x0000–0x000D`	Coils	Digital Outputs DO0–DO13
`0x0100–0x010D`	Discrete	Digital Inputs DI0–DI13
`0x0200–0x0203`	Holding	Analog Inputs AI0–AI3

Troubleshooting¶

Issue	Fix
Can't connect via Ethernet	Check IP address; default is `192.168.1.100`
Output relay not switching	Verify load wiring and relay common connection
Analog reading incorrect	Check DIP switch position for V/mA mode
