What is FactoryTalk Gateway?

FactoryTalk Gateway is an OPC Data Access (OPC-DA) 2.05a-compliant OPC server. It enables OPC clients to connect to FactoryTalk® applications that contain RSLinx Enterprise and FactoryTalk View Site Edition (SE) servers and access tag data within those applications.

Why is OPC needed?

An OPC server reduces the load on data source devices as it enables communication with several applications, while having only one connection with the data source. This reduces multi-access from the data source, and hence reduces the load on the data source.

Is kepware an OPC server?

What is the difference between OPC and OPC UA?

The most significant difference between classical OPC and OPC UA is that it doesn’t rely on OLE or DCOM technology from Microsoft that makes it possible to implement it on any platform if that being Apple, Linux (JAVA) or Windows. The other very important part of UA is the possibility to use structures or models.

What is OPC used for?

OPC is a software interface standard that allows Windows programs to communicate with industrial hardware devices. OPC is implemented in server/client pairs. The OPC server is a software program that converts the hardware communication protocol used by a PLC into the OPC protocol.

What is OPC technology?

​OPC (OLE for Process Control) communicates information from a data source such as a server to any client application in a standard way without requiring the application to have any specific knowledge about the data source such as its communication protocols.

How does OPC DA 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.

Is OPC UA free?
