发行说明
6.10.623.0
2021/2/23
- Removed non-inclusive terms out of respect for users of our software.
6.9.572.0
2020/6/2
- Fixed an issue where the Request Timeout was incorrectly used instead of the Connect Timeout when the driver was not connected.
6.7.1046.0
2019/6/18
- Expanded the Connect Attempts feature introduced for Ethernet Encapsulation in the 6.6.348.0 release to honor the connection timeout when not connected.
6.6.348.0
2018/11/14
- 添加了“连接尝试”设置，用于指定最大尝试次数。当连接类型为“以太网封装”(Ethernet Encapsulation) 时，可在设备属性的“定时”(Timing) 组中找到该新设置。
5.20.396.0
2016/5/3
- Added the ability to format Date and Time values as ACSII numeric strings.
5.19.467.0
2015/10/20
- Added support for Advanced Statistics Tags, including _CommFailures, _ErrorResponses, and more.
- Enhanced the driver to allow the RTU P619 value to be queried prior to a Dynagraph request. The result of this request determines the “position inclusion and type character” parameter when building the Dynagraph transaction.
5.10.205
2012/11/13
Updated the driver with the new Connection Sharing feature.
5.9.170
2012/6/26
Added the new device-level internal tag "_FailedConnection" that indicates the driver failed on its attempt to connect to the device.
5.8.109.0
2012/2/21
Fixed a Communication Serialization bug that prevented the driver from releasing communication control when there were many memory and/or Write Only tags with scan rates.
5.7.84.0
2011/10/24
- Added channel serialization.
- Added support for the following models: EPIC, M2000, WellPilot Classic, 8800, 8750, 8650, and 8500.
- Added Inter-Device Delay
5.6.122.0
2011/7/25
- New serial driver that allows the 8500 Protocol to communicate with Weatherford model 8500 RPOC controllers. Ethernet Encapsulation is supported.
