# Industrial PLCs

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

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