The TOP Server® DDE Client Driver provides a communication interface to existing DDE server applications with the same level of performance, stability and ease of configuration as any other TOP Server driver.
This driver provides data exchange between OPC UA, OPC DA, SuiteLink and any DDE server application that supports Microsoft standard DDE. Do you have existing software drivers in your facility that use DDE to interface to other applications and you need to connect them to the latest software using the OPC specification to connect to drivers? If so, this product provides a solution. You can give your existing DDE applications new life by putting this bridge in front of them, saving you the expense and engineering time of replacing them with new applications. Data acquisition is optimized based on upstream client demand while data integrity is ensured using extensive error handling.
NOTE: Special considerations are required when using DDE depending on the operating system where TOP Server is installed. Please select one of the following options that corresponds to your operating system for additional details. Note that it's possible your IT department has disabled DDE.
