Hi MK,<br><br>Tag use in the OPC UA server is not limited. At some point however it makes sense to start an additional instance of the OPC UA process gateway for load distribution, when large tag volumes&nbsp; are used combined with a large number of connected OPC UA clients and a high change rate. The number of sessions is limited to 100 per instance of the OPC UA process gateway.<br><br>Best regards,<br>Mark
