Scheduler
产品概览
利用 Scheduler for KEPServerEX，用户可以将来自客户端的数据请求计划移至服务器，从而在带宽有限的网络中优化客户端通信。该插件可以按照每天的时间或频率为来自多个设备的特定标签定义轮询时间表。该高级插件还让用户能够定义不需要轮询的例外时段。每个时间表都可以配置自己的优先级，以便确定在发生冲突时优先奉行哪一个时间表；服务器会相应地更新数据到客户端。

6.2
2017/6/8

6.0.2107.0
2016/11/15
- The Scheduler advanced plug-in is now represented in the unified tree view to improve visibility and editing.
- Scheduler configurations can now be added, read, updated, and deleted through the Configuration API Service.
5.18.662.0
2015/6/23
- Added support for tags referenced via the Alias Map.
- Writes to the "_Poll" tag that do not result in a demand poll now correctly fail if the schedule is disabled or already polling.
- Added support for adding and editing a single tag for a device.
- Fixed an issue where reading static tags with a Default data type resulted in an initial bad-quality read.
- Added support for prioritization of reads across virtual networks by setting the channel-level Network mode to Priority mode.
- If a client reads a scheduled tag before the schedule has requested the data from the device, the Scheduler returns an initialized time set to the current system time.
- Fixed potential instability issues when deleting schedules actively polling.
- If a tag referenced by a schedule is deleted, the bad quality is reported for the tag.
- Added support for 64-bit integers.
- Added a Daylight Saving Time Transition Behavior setting so schedules can respect the schedule interval or respect the absolute time.
- Added support for specifying the data type for Dynamic tags using the @type syntax.
- Disabling a schedule now disables references to tags in the schedule. This allows edits to devices and servers without deleting the schedule.
- Schedules that contain channels with unscheduled devices are indicated with a warning to indicate there is a mix of scheduled and unscheduled devices in a channel.
- Devices added to a schedule are automatically placed in "Do Not Scan, Demand Poll Only" mode when a tag from the device is added to a schedule. The device reverts to the previous scan mode when all its tags are removed from the schedule.
- Added a "_SecondsInOverride" System tag to show how long a device has been in Override mode.
- Changing a schedule's priority posts an Event Log message.
- Added device icons to show when a device is in override, disabled, etc.
- Added validation to CSV import to handle invalid files more gracefully.
- Added support for a channel level statistics tag "_NextReadPriority" to show the priority of the next read. This improves troubleshooting when using priority-based Virtual Networks for drivers that support Communication Serialization.
- Fixed instability in the configuration when double-clicking an empty Detail View.
5.17.495.0
2015/2/24
- Added the new Scheduler Plug-In, which decouples the client scan rate from the rate at which devices are polled. The server can poll for data once a day, every five minutes, and so forth. Clients get updates from the server cache.
