Modbus Server

PreviousModbus TCP/IPNextAnalog to Modbus/RS485 Server (Slave)

Last updated 11 days ago

Typically, YuDash IoT devices act as Modbus master (client) reading data from the instruments or PLCs. The data is sent to some cloud server through MQTT or REST API.

There are many applications in which aggregated data is required on SCADA systems. For these applications, YuDash IoT devices act as per Modbus Server (Slave) on a given RS485 port or Ethernet (Modbus TCP/IP).

Effectively any inputs read by YuDash (4-20mA analog inputs, RS485 or even MQTT subscribe) can be provided on Modbus server on configured port. The YuDash IoT devices can be configured as dedicated Modbus server or they can be configured in parallel to regular cloud data push.

Modbus Server feature is explained in following tutorials:
