产品概览
Modbus Serial 设备驱动与 KEPServerEX 协同工作，在 OPC 客户端和使用 Modbus Serial 协议的 PLC 及其他设备之间提供数据交换。KEPServerEX 基于客户端需求自动优化您的数据采集过程。我们强大的错误处理能力可确保数据完整性。
已添加特殊处理以支持 OMNI 流量计算机的原生内存格式，包括字符串支持。通过配置其中的具体参数，该驱动可以连接大量兼容 Modbus Serial 协议的设备，包括 JBUS。
Modbus Serial 驱动现在可与 Modicon Concept 和 ProWORX 编程包直接集成。如果您使用其中任一编程包，您能够将 PLC 应用程序中使用的标签直接导入到 KEPServerEX 中。通过这一步骤，您的 OPC 客户端应用程序可立即使用所有相关 PLC 数据，从而节省时间。

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。
6.1.601.0
2017/4/4
- 从 Daniel S500 型号中删除了冗余的默认设置。
- 解决了以下问题：地址指定为十六进制时，数组长度转换为十六进制。
- 通道限制从 256 提高到了 2048。
6.0.2206.0
2018/6/11
- 删除了 DanielS500 设备 FirstWordLow 设置的硬编码。
- 将通道限制从 256 增加到 2048。
5.21.235.0
2018/6/11
- 将数组长度的格式更改为在将地址指定为十六进制时数组长度格式始终为十进制。
- 删除了 Daniel S500 设备的 m_bFirstWordLow 硬编码。
5.21.114.0
2017/3/20
- 解决了以下问题：Daniel S500 型号的“数据编码”(Data Encoding) 设备属性下的“首字排序为低”(First Word Low) 设置始终启用。
- 解决了 5.19 版本中的以下问题：如果地址格式指定为十六进制，十进制数组长度将转换为十六进制。
5.19.467.0
2015/10/20
- Added support for padding addresses for both 5 digit and 4 digit format. If 5 digits or more are used, the address entered is padded to 5 digits (400001). If 4 digits or fewer are used, the address entered is padded to 4 digits (40001). This applies to all model selections except Omni and Daniel S500.
5.18.662.0
2015/6/23
- Enhanced the driver to support Advanced Statistics tags, including "_CommFailures" and "_ErrorResponses".
- Fixed an issue where switching models did not update controls availability.
5.10.205
2012/11/13
- Updated the driver with the new Connection Sharing feature.
- Fixed an issue where the RTS Delay and Inter-Request Delay settings were not respected during the write portion of a Read/Modify/Write transaction.
5.9.170
2012/6/26
- Increased the character limit of the tag Description field from 64 to 255.
- 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
Added support for Channel Serialization.
5.6.122.0
2011/7/25
- Fixed a potential heap corruption issue (when an expandable buffer was being overwritten) by reading an Omni Custom Packet Tag. A maximum size of 250 bytes was assigned for an Omni Custom Packet Tag instead of allowing the tag data type to determine the buffer allocation size.
