Software Toolbox's TOP Server Version 5.6 OPC and native HMI device connectivity software offers media-level redundancy functionality
Software Toolbox's TOP Server Version 5.6 OPC and native HMI device connectivity software application is powered by Kepware. TOP Server 5.6 introduces media-level redundancy functionality for increased device availability. There are two basic types of redundancy available. Communications path redundancy (CPR) establishes redundant physical connections to the same device. Device pair redundancy (DPR) enables running two identical devices with the same logic as a redundant pair, allowing failover in the event that one of the devices becomes disabled. Both types of redundancy can be used in conjunction.
The Version 5.6 release also includes the addition of device-level scan rate modes. By default, TOP Server Version 5.6 will respect the scan rate specified by the client application. Two new modes are also available to override the client scan rate. The first option specifies a scan rate floor that restricts TOP Server to polling no faster than the specified floor. The second option fixes the scan rate at a specified level.
The OPC DA ProgID redirect functionality is designed to allow users to map any OPC ProgID to TOP Server Version 5.6 for use in OPC DA client applications. In addition, the Version 5.6 release includes full support for Hyper-V virtualization.
