A great solution/s to interconnect Modbus TCP/IP devices on OPC DA Client network.

Modbus TCP/IP

Modbus TCP/IP is a widely used communication protocol in industrial automation systems, allowing for the exchange of data between devices such as programmable logic controllers (PLCs) and sensors. It is based on the TCP/IP protocol, which enables communication over Ethernet networks. Modbus TCP/IP supports a wide range of functions and data types, including discrete inputs and outputs, analog inputs and outputs, and registers. With its simplicity and versatility, Modbus TCP/IP has become a popular choice for industrial applications, providing reliable and efficient communication between devices.

ProtoConvert can supply and support gateways that can have a Modbus TCP/IP client or server interfaces.

When a gateway is configured as a Modbus TCP/IP Client it would keep reading data from the field devices using Modbus TCP/IP protocol. It will also be possible to program the gateway to relay commands to the field devices (if protocol implementation supports, please check datasheet for details). Hence when used as a Modbus TCP/IP Client the gateway reads data from Modbus TCP/IP Servers and makes the data available on a variety of other protocols like Modbus, BACnet, SNMP, Lutron Machine and many others.

When a gateway is configured as a Modbus TCP/IP Server it can be connected to a Modbus TCP/IP Client and be a source of data. It would respond to the polls from the Modbus TCP/IP Client and publish the data as per the internal configuration. Hence by using the gateway as a Modbus TCP/IP Server it is possible to publish data from other protocol networks on the Modbus TCP/IP network.

OPC DA Client

OPC DA Client is a software application that allows you to communicate with OPC DA servers, which are used to connect to industrial automation devices and systems. With OPC DA Client, you can monitor real-time data from these devices, control their operations, and receive notifications about events and alarms. This software is commonly used in various industries, including manufacturing, oil and gas, and pharmaceuticals, to improve operational efficiency and reduce downtime. Whether you’re an engineer, technician, or operator, OPC DA Client provides an intuitive and powerful interface to access and manage data from your industrial equipment.
