OPC Protocol Conversion Solutions 

The OPC standards are very successful in helping users integrate different systems, but over their long history, there are different types and versions of the standards, and not all automation systems have the same standards in use. With that and DCOM hardening impacts on OPC Classic, comes the need for tools to help you integrate between the standards such as DA, UA, A&E, A&C but also non-OPC standards such as MQTT, databases, historians, Modbus, and more. 

DataHub is a solution that bridges these standards with rapid setup convertors that can also move data between systems using the different standards using data bridging functionality. 

Here are some examples and links where you can learn more. Ready to try? Complete the form at the right. 

OPC DA/UA and UA/DA Conversion

The original OPC Data Access or DA standard is everywhere but newer systems use OPC Unified Architecture or UA standards. With Microsoft's security hardening of DCOM, used when using OPC DA over a network, more systems need to move to OPC UA. DataHub's OPC Gateway solution makes that move easy and cost effective for DA and UA client/server solutions. DataHub OPC Gateway Licenses are competitively priced and free video training included for DA to UA and UA to DA conversion.

OPC Alarms & Events to OPC UA Alarms & Conditions Conversion

Like OPC DA, the OPC Alarms & Events (A&E) specification has been around a long time and is found in many systems, especially DCS's.  As alarm management client applications move to OPC UA Alarms & Conditions (A&C), the need for interoperability is clear. For example the Emerson PlantWeb application expects to receive alarm data via OPC UA A&C.  DataHub has that conversion covered.

See how in our video tutorial and then give it a try yourself

OPC Alarms & Events to OPC DA Conversion

What if your HMI, SCADA, Historian or other application doesn't support OPC A&E or OPC UA A&C yet you need to get that alarm information in?  As long as your system is an OPC DA or UA client, the DataHub can automatically split out the tags in the alarm structures into individual tags that you can then read or subscribe to using OPC DA or UA as single tags.  Learn how in our free video tutorial and then give it a try.

OPC to MQTT and MQTT to OPC

DataHub provides smart MQTT client & MQTT broker functionality with SparkplugB support (V10+) that is tightly and automatically integrated with OPC interfaces (DA, UA, A&E, A&C) so that once you bring data into DataHub, from any source, it can be used with MQTT.  DataHub is the only industrial broker that automatically converts from OPC UA or OPC DA to MQTT and vice-versa without configuring multiple applications.

Database to OPC or OPC to Database + Historians

Need to read data from a database and expose it via OPC standards? Or source OPC data and log it to databases or even historians?  DataHub has you covered either way beyond the basic needs though. With DataHub store-and-forward you can be sure data gets through on intermittent connections.  With DataHub secure tunneling, you can move data between IT/OT securely including via DMZ's or proxy servers to get it to where it needs to be.   Learn more about DataHub Database or DataHub Historian Integration.

Modbus to OPC 

Modbus is everywhere, and DataHub is a cost effective Modbus TCP OPC DA & OPC UA server application at only $1038 for a single machine license that gives you much more than just an OPC server that is a client to Modbus TCP devices.

Once you have Modbus data in DataHub you can use any of DataHub's extensive other features such as bridging, tunneling, logging, and more.  Learn more then give it a try.
