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。

2017/4/4
- Removed redundant default setting from the Daniel S500 model.
- Fixed an issue where array length was converted to hex when the address is specified as hex.
- Increased the channel limit from 256 to 2048.
6.0.2107.0
2016/11/15

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.
5.4.131.0
2010/10/28
- Increased the number of channels from 100 to 256.
5.2.133.0
2010/2/18
- Fixed issue with write-only tags introduced in 5.0. The value of the tag was not updating when a value was written to it. The correct value was written to the device, just not displayed in the data client.
5.1.71.0
