Is OPC TCP or UDP?

Summary:

OPC UA is a platform-independent standard for the secure exchange of industrial automation data. It uses TCP/IP and web protocols for communication and can be accessed through an OPC server. OPC UA can use both TCP/IP and UDP/IP for PubSub communication. TCP port 48031 is the default port for the MTConnect OPC UA server.

1. What protocol does OPC use?
OPC uses TCP/IP and web protocols for communication, making it completely platform-independent.

2. What is the TCP port for OPC?
The TCP port for the MTConnect OPC UA server is 48031 by default. This port can be changed during the MTConnect setup.

3. Does OPC UA use UDP?
OPC UA can use both TCP/IP and UDP/IP for PubSub communication.

4. What type of communication is OPC?
OPC is an interoperability standard for the secure exchange of industrial automation data. It enables devices from different vendors to exchange information.

5. Is OPC a TCP/IP protocol?
OPC UA relies on TCP/IP as the transport layer for its Connection Protocol.

6. Does OPC use TCP/IP?
Both EtherNet/IP and OPC UA use standard Ethernet and TCP/IP for communication.

7. How does OPC protocol work?
An OPC server translates the hardware communication protocol used by a PLC into the OPC protocol. An OPC client software connects to the hardware and communicates with the OPC server to exchange data or send commands.

8. What is the difference between OPC and Modbus TCP?
OPC is a software-to-software communication standard for operator display, while Modbus/Profibus is a hardware-to-hardware communication standard for control.


Is OPC TCP or UDP?

What protocol does OPC use

OPC UA has become completely platform-independent through TCP/IP and web protocols for communication. An OPC server, which makes its data available in the network, can be addressed via these protocols.

What is the TCP port for OPC

The TCP port on which the MTConnect OPC UA server is listening for connection requests of the OPC UA clients. The default port is 48031. The default port number is set during the MTConnect setup. You can change the default value here.

Does OPC UA use UDP

OPC UA communication is based on standard protocols layers like TCP/IP for Client/Server communication. For PubSub communication, it can use both TCP/IP and UDP/IP communication layer.

What type of communication is OPC

Open Platform Communications (OPC) is an interoperability standard for the secure exchange of industrial automation data. It is designed to be platform-dependent so devices from different vendors can exchange information.

Is OPC a TCP IP protocol

TCP/IP is a ubiquitous protocol that provides full-duplex communication between two applications. A socket is the TransportConnection in the TCP/IP implementation of the OPC UA Connection Protocol.

Does OPC use TCP IP

Let's start with the similarities between EtherNet/IP and OPC UA. Both use standard Ethernet and TCP/IP.

How does OPC protocol work

The OPC server is a program that translates the hardware communication protocol used by a PLC into the OPC protocol. The OPC client software is a program that connects to the hardware, such as an HMI. The OPC client communicates with the OPC server to receive data or send commands to the hardware.

What is the difference between OPC and Modbus TCP

OPC is communicating software-to-software for operator display while Modbus/Profibus is communicating hardware-to-hardware for control.
