# Industrial PLCs

YuDash IoT gateways are integrated with various industrial PLCs and HMIs for IoT connectivity in a secure manner. Typically [Modbus](https://docs.yudash.com/device-to-cloud-api/industrial-protocols/modbus) protocol is used for one way or two was communication. Option of both [Modbus-RS485 ](https://docs.yudash.com/yudash-iot-devices/lynx-user-manual/lynx-settings/modbus-rs485)and [Modbus TCP/IP](https://docs.yudash.com/yudash-iot-devices/lynx-user-manual/lynx-settings/modbus-tcp-ip) is available in YuDash IoT devices.

Following are some of popular PLCs which have been integrated with YuDash IoT gateways.
