IoT Gateway
产品概览
IoT Gateway 是扩展 KEPServerEX 连接平台功能的一个高级插件。它呈现 RESTful Web 服务器以便与 MES 和其他系统中的 Web 服务集成，并将实时工业数据直接无缝地流式传输到整个企业的设备云和大数据分析平台。
IoT Gateway 将运营技术与 IT 联系起来，以支持工业物联网 (IIoT)。这使得决策者能够搜索、监控、分析和呈现数据，以便实时洞察车间运营情况，从而提高系统安全性、改善客户服务、精简自动化过程并提高整个企业的决策质量。
借助企业解决方案和基于云的解决方案，组织能够搜索、监控、分析和呈现来自 PAC、PLC、RTU、流量计算机、OPC 服务器及其他工业硬件和软件的 KEPServerEX 生成的数据。Kepware 已经与大数据和分析提供商合作，以洞察工业设备与系统的运营和状况。
测量、验证和持续调试：确保现场设备如期运行。
容量计划：监控设备或系统计划外停机风险的数据。
根本原因分析和远程故障排除：更好地了解特定设备上出现特定故障的原因并提高效率。
异常和异常值检测：识别可能标志着早期设备生产或部署问题的异常值。
安全和合规：了解可能让机器或人员陷入风险的系统性能或设置点，并快速制定和访问用于合规的报告。
网络安全：改善工业体系中的安全态势，以缓解出现的网络安全威胁。

6.11.718.0
2021/12/21
- Fixed an issue where very small deadband values would be truncated when exporting tags as CSV.
- Fixed an issue where '$' would incorrectly be removed if it was the first character of an MQTT topic name.
- Fixed an issue in the where the _PublishesSent and _DroppedEvents system tags were not updating.
- Fixed an issue where the Scan Rate specified in the tags was not respected.
- Fixed instability issues that could occur on server startup.
- Added the ability to specify different ISO timestamp formats in the payload.
- Added the ability to publish additional tag attributes and a linefeed in the message templates. Refer to help for the full list.
6.10.659.0
2021/8/10
- Fixed an issue where some system tags were not being updated
- Fixed an issue where the IoT Gateway service would sometimes not start up correctly and need to be restarted.
6.10.623.0
2021/2/23
- Fixed an issue where REST Client Agent expansion message error messages could be empty.
- Fixed an issue in which caused failed authentication could cause the IoT Gateway service to lock up.
- Clarified event log message posted when the event buffer is full for REST Clients and MQTT Client Agents.
6.9.636.0
2021/8/10
- Resolved issue with failed authentication through the IoT Gateway that could cause the service to lock up.
6.9.572.0
2020/6/2
- Updated Java third-party libraries to address security vulnerabilities.
- Fixed an issue where license status was incorrectly reported as “unlicensed” in the Agent properties.
- Fixed an issue where Boolean values reported to the server with underlying non-zero values except '-1' were reported as ‘false’ by agents.
- Resolved issue with the Rest Client Agent “Publish as Media Type” didn't match the option set in the Configuration.
- Fixed an issue where a deadlock could occur during explicit reads.
6.8.796.0
2019/12/17
- Agents can be configured to only send updates in which the value has changed, ignoring quality-only changes.
6.7.1046.0
2019/6/18
- Enhanced the MQTT Agent to allow the use of ‘$’ in the first character of the Topic.
6.3.273.0
2017/9/27
- 解决了 MQTT 代理在通信中断后不重新连接的问题。
6.2
2017/6/8

6.1.601.0
2017/4/4
- The IoT Gateway is now accessible via the Configuration API.
- Fixed an issue where the MQTT client agent was not shutting down correctly, causing the service to fail on attempts to reconnect or reinitialize from the Configuration.
- Added generic support for client-side SSL/TLS certificates. Support has been verified with the following MQTT brokers:
- AWS IoT SSL/TLS
- Azure IoT Hub SSL/TLS
- Enhanced input validation and error handling for MQTT broker URLs. Prior to this update, a trailing "/" added to an MQTT URL in the IoT Gateway MQTT agent would not connect or produce a relevant event log message.
- Added support for explicit device reads to the Rest Server agent. This can be useful when the client is aware of when a data change should have occurred, as an alternative to polling for updates.

- Fixed a defect where write requests would timeout if the device's Scan Mode was set to "Demand Poll Only."
- Fixed an issue where tag scan rate would revert to a default of 10ms if set higher than 32767.
- Fixed an issue where the REST Client Agent was sending an invalid Accept header, causing the connection to be rejected with an HTTP error 406.
- Expanded and corrected error handling on the MQTT engine to provide improved feedback.
- Added support for an advanced template to format data for improved control over the payload being sent from the REST Client and MQTT agents. In addition to JSON, XML and CSV can be generated using this template.
- Added support for writing to Array data types (with the exception of String Arrays).
- Added support for writes via MQTT agents. The MQTT agent can be configured to subscribe to a topic on the MQTT broker to allow other publishers to write to tags under that agent.
- Added support for users to enable or disable connections from Cross-Origin Resource Sharing (CORS) sources. This setting can be used when accessing the IoT Gateway REST Server agent from a custom web page.
