## Article

**INTRODUCTION**

The IoT Discovery Gateway is a powerful and complete testbed for connected products and services powered by Electric Imp. It is based on the Electric Imp imp005 module.

**HOW TO USE**

You can confirm the sample source code using PLC

- [PLC-connected Water Pump Controller](https://github.com/electricimp/examples/tree/master/AutodeskFusionPLC)

### **Modbus Devices**

Electric Imp provides a series of Modbus libraries to help you work with Modbus devices attached to the IoT Discovery Gateway’s Ethernet or RS-485 ports:

- [Modbus Serial Master Library](https://developer.electricimp.com/libraries/hardware/modbusserialmaster) — Communicate with Modbus devices via the RS485 and RS232 protocols

- [Modbus Serial Slave Library](https://developer.electricimp.com/libraries/hardware/modbusserialslave) — Communicate with a Modbus Master via the RS485 and RS232 protocols

- [Modbus TCP Master](https://developer.electricimp.com/libraries/hardware/modbustcpmaster) — Communicate with Modbus devices via TCP/IP

- [Modbus RTU](https://developer.electricimp.com/libraries/hardware/modbusrtu) — Create and parse Modbus Protocol Data Units
