The OPC Data Manager (ODM) serves as a software tool that facilitates the transfer of data between various OPC servers. It is particularly useful when there is a need to share, map, and connect OPC information across multiple control systems, such as a PLC and a DCS. ODM enables this vital connectivity using readily available, standard software solutions. To enhance the longevity of your control system setup, Matrikon OPC UA Tunneller is a valuable asset, ensuring that you are prepared for the growing adoption of OPC UA. This tool alleviates concerns regarding the interoperability between OPC Classic and OPC UA, as well as cross-network communications. Choosing this solution allows for the swift and effective establishment of connectivity between OPC Classic and Classic systems, as well as bridging from Classic to UA. Typically, data sharing between OPC-enabled systems occurs with one application acting as an OPC client and another as an OPC server; however, there are instances where both applications function as servers without a client involved. Ensuring smooth communication in these scenarios is crucial for maintaining efficient operations.
