Siemens S7 200 OPC Server - KEPServerEX OPC Servers

Overview

Kepware's 32 bit Siemens S7-200 device driver works in conjunction with our OPC Server KEPServerEX, to provide data exchange between OPC Clients and Siemens S7-200 PLCs using PPI (11Bit) or PPM (10Bit) protocol. Direct support for the EM241 Modem Module. KEPServerEX automatically optimizes your data acquisition based on client demand. Data integrity is ensured with our extensive error handling.

This product is part of a Suite and when it is purchased you will receive all drivers in the suite. To see the list of drivers in this Siemens OPC Server Suite.

Protocol

Communication Protocol

Point-to-Point (PPI) S7-200 Communications Protocol (11 bit Mode)
Point-to-Point Modem (PPM) S7-200 Communications Protocol (10 bit Mode)
Note: Normally the driver operates using the standard 11 bit PPI protocol. If the use of the EM 241 modem module is required the S7-200 PPM model must be selected. The S7-200 PPM model allows the driver to operate in a 10 bit mode which is much more compatible with a wide range of off-the-shelf modems. The 10 Bit PPM mode can also be used directly on the programming port of the PLC. To enable 10 bit PPM mode the S7-200 programming cable must be set to 10 bit mode.

Revisions

Siemens S7 200 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.

Driver updates below coincide with Server Release V4.222.376 (01/26/07)

Siemens S7-200 (V4.31.64)

- Fixed issue where successfully reading Timers and Counters from certain S7-200 CPU's would resulted in a Bad Quality/"Device Not Responding" condition.

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)

Siemens S7-200 (V4.25.59)

- Added transaction ID to read/write frames to facilitate packet synchronization over noisy networks resulting in duplicated/resent packets.

Driver updates below coincide with Server Release V4.150.304 (11/12/04)

Siemens S7-200 (V4.24.53)

- Fixed blocking issue with reading timer done bits (Tx @ BOOL) above timer 16.
- Fixed byte swapping issue reading and writing DWord/Long/Float arrays.

Driver updates below coincide with Server Release V4.110.270 (3/22/04)

All Drivers

- Library fix affecting all drivers.

Driver updates below coincide with Server Release V4.102.251 (9/25/03)

Siemens S7 200 (V4.22.47)

- Fixed issue where the driver would shut down a block of data when an error was received on the request. Normally this would be good but in this case a customer was getting random errors from the PLC that would cause the block to be disabled.

Driver updates below coincide with Server Release V4.90.237 (5/10/03)

All Drivers

All drivers have been updated to support 32 channels. (Exceptions are DDE Client driver, Modbus Plus, and SattBus).
