产品概览

Modbus Ethernet 设备驱动与 KEPServerEX 协同工作,在 OPC 客户端和使用 Modbus Ethernet 协议的 PLC 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。

Kepware 的 Modbus Ethernet 驱动实施同时支持主站和从站模式。从站模式允许服务器接收其余 Modbus Ethernet 设备的例外数据。

Modbus Ethernet 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。

2015/10/20

  • Added support for Advanced Statistics Tags, including _CommFailures and _ErrorResponses.
  • 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 Applicom and Fluenta.
  • Improved message logging to include socket errors in the Event Log.

5.18.662.0

2015/6/23

  • The driver now reports an error when receiving a message length in the Modbus header that is less than the actual message length.
  • Added support for "Double Precision Unsigned Long" encoding of Ints and UInts.

5.16.722.0

2014/10/21

  • Added the new CEG model and made protocol changes to slave mode to support a maximum of 500 register and 8000 coil tag reads.
  • Added the new CEG model and made protocol changes to slave mode to support a maximum of 500 register and 8000 coil tag reads.
  • The driver will now attempt a retry on receipt of a send socket error. Prior to this change, certain devices could respond with a socket error after the initial connection and cause an unnecessary disruption in communication with that device.
  • Fixed an issue introduced in KEPServerEX version 5.14 where tags on one or more devices may stop being serviced if another device under a channel has been deleted.

5.15.585.0

2014/7/22

  • Changed the driver's minimum Timeout setting from 50 milliseconds to 10 milliseconds.
  • Fixed an issue where a buffer overflow could result in the driver writing to erroneous coils.
  • Added support for importing string type tags via the Variable Import Settings page.

5.14.493.0

2014/3/4

  • Fixed an issue involving register block sizes of 1 to 4, or coil block sizes of 8 or 16 when using packed coils. The issue either resulted in a failure to add tags from a client or in tags being set to bad quality because of a malformed packet.

5.14.491.0

2014/2/18

  • The driver now closes socket connections when a device is disabled.
  • Created a new CEG model.

  • Added the ability to append an 'H' or 'L' to the end of an Applicom string address when defining byte order.
  • Fixed an issue where concurrent writes to multiple bits within the same register were not being retained if the channel was configured to use more than one socket per device and the device property "Use holding register bit mask writes" was unchecked.
  • Corrected Applicom string address syntax to use string length as length in words, not bytes.

5.6.122.0

2011/7/25

  • Added an Applicom model type to support Applicom-centric address syntax for Modbus Ethernet enabled devices. Selecting the Applicom model in the Device Wizard prompts a "Sub-Model" dialog that includes options for "Generic Modbus," "TSX Premium," and "TSX Quantum."
