The **Delta PLC** is one of the most widely used compact PLCs in Asian manufacturing — small machine builders, packaging lines, and OEM equipment. This guide walks you from unboxing through your first running ladder program.

## 1\. Hardware Overview

The PLC series comes with 16 to 32 I/O points in a compact DIN-rail enclosure. Power supply is typically 24V DC. Built-in features include high-speed counters, PWM outputs, and RS-485 communication.

- **Digital Inputs:** 24V DC sink/source
- **Digital Outputs:** Relay or Transistor (NPN/PNP)
- **Built-in Comm:** RS-232 + RS-485 (Modbus RTU)

## 2\. Installing PLC software

Download **PLC software** from the Delta Industrial Automation website. It's free and installs in under 5 minutes. After installation, set communication to "COM Port" with default 9600 baud, 7-E-1.

## 3\. Your First Ladder Program — Start/Stop Motor

Create a new project, select PLC model, and write the classic seal-in circuit:

- **X0** — Start push button (NO)
- **X1** — Stop push button (NC)
- **Y0** — Motor contactor output

> **💡 Pro Tip**Always include a hard-wired safety stop independent of the PLC logic. Software-only e-stops are not compliant with industrial safety standards.

## 4\. Upload & Test

Connect the PLC, switch it to RUN mode in PLC software, and download the program. Press the Start button — the motor output Y0 should latch ON. Press Stop — it releases.
