IoT Gateway

產品概覽

IoT Gateway 是擴展 KEPServerEX 連接平臺功能的一個高級插件。它呈現 RESTful Web 服務器以便與 MES 和其他系統中的 Web 服務集成，并將實時工業數據直接無縫地流式傳輸到整個企業的設備云和大數據分析平臺。

IoT Gateway 將運營技術與 IT 聯系起來，以支持工業物聯網 (IIoT)。這使得決策者能夠搜索、監控、分析和呈現數據，以便實時洞察車間運營情況，從而提高系統安全性、改善客戶服務、精簡自動化過程并提高整個企業的決策質量。

借助企業解決方案和基于云的解決方案，組織能夠搜索、監控、分析和呈現來自 PAC、PLC、RTU、流量計算機、OPC 服務器及其他工業硬件和軟件的 KEPServerEX 生成的數據。Kepware 已經與大數據和分析提供商合作，以洞察工業設備與系統的運營和狀況。

測量、驗證和持續調試：確?，F場設備如期運行。

容量計劃：監控設備或系統計劃外停機風險的數據。

根本原因分析和遠程故障排除：更好地了解特定設備上出現特定故障的原因并提高效率。

異常和異常值檢測：識別可能標志著早期設備生產或部署問題的異常值。

安全和合規：了解可能讓機器或人員陷入風險的系統性能或設置點，并快速制定和訪問用于合規的報告。

網絡安全：改善工業體系中的安全態勢，以緩解出現的網絡安全威脅。

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

  • 解決了 MQTT 代理在通信中斷后不重新連接的問題。

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.

  • Corrected an issue where the MQTT Agent could block all other agents if it did not connect on the initial attempt.
  • Corrected an issue where “Bad” quality updates were repeatedly sent to endpoints due to being interpreted as data changes.
  • 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.
