Overview
OverviewKepware's 32 bit PLC Direct Ethernet device driver works in conjunction with our OPC Server KEPServerEX, to provide data exchange between OPC Clients and PLC Direct Ethernet UDP protocol compliant PLCs. KEPServerEX automatically optimizes your data acquisition based on client demand. Data integrity is ensured with our extensive error handling.
This driver is part of the AutomationDirect OPC Server Suite. Purchasing either the AutomationDirect ECOM OPC Server, the AutomationDirect DirectNet OPC Server, or the AutomationDirect K Sequence OPC Server entitles you to all of the drivers.

AutomationDirect ECOM OPC Driver Revisions| Driver updates below coincide with Server Release V4.270.416.0 (09/27/07) |
| All Drivers |
| - Fixed issue where server menu buttons like 'New', 'Open', 'Exit' would become permanently disabled when attempting to perform auto tag generation on a driver that had missing runtime dependencies. - Fixed issue that could occur when multiple items with the same scan rate are read by exception and another item is added/asynchronously read/removed at that same rate. This issue resulted in stale data for those tags read by exception. |
| Driver updates below coincide with Server Release V4.264.401 (06/01/07) |
| All Drivers |
| - Fixed issue in the driver library where it was possible to delete a tag prior to stopping it. This would result in the accessing of invalid memory which could eventually result in an exception that would prevent a channel from processing any tags. |
| AutomationDirect ECOM (V4.91.83) |
| - Added UDP Port device property. Default ECOM Port is 28784. |
| Driver updates below coincide with Server Release V4.222.376 (01/26/07) |
| AutomationDirect ECOM (V4.81.79) |
| - Fixed string write issue when string values were an odd number in length. |
| Driver updates below coincide with Server Release V4.210.367 (11/17/06) |
| All Drivers |
| - Fixed issue where a rapid sequence of item add, sync read, and item remove requests could result in bad OPC quality for some items included in a block sync read and/or sync read timeouts. - Fixed issue with Unsolicited UDP Mode Ethernet Encapsulation mode, where driver would stop receiving unsolicited messages after sending a message. |
| Driver updates below coincide with Server Release V4.180.338 (8/12/05) |
| AutomationDirect ECOM (V4.70.74) |
| - NetEdit launch has been moved to General tab on Device Properties dialog.
- Fixed issue in which reading a block of 32-bit values (i.e. Float) could exceed the maximum number of bytes allowed by the device, resulting in a 'Device Not Responding' error. - Fixed write toggle issue when writing to Control Relays (C). - Added array support for Data Words (V). Support includes Word, Short, BCD, DWord, Long, LBCD and Float arrays. |
| Driver updates below coincide with Server Release V4.170.328 (5/19/05) |
