Revisions

Allen-Bradley ControlLogix 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.

Allen-Bradley ControlLogix (V4.110.181.0)

- Fixed an auto tag generation error that would be reported if a User-Defined Instruction was encountered in the import.
- Updated auto tag generation event log message to include the number of OPC tags that will be generated.
- Added support for Logix Data Type LINT. Data is accessible via Double/Double Array (Signed 64 bits) and Date. Date is the default data type.
- Fixed resource leak issue when cleaning up a socket connection to the device.
- Fixed communications issue introduced in released build 169 affecting ENI models.
- Updated predefined types: AXIS_SERVO, AXIS_SERVO_DRIVE, AXIS_VIRTUAL, COORDINATE_SYSTEM, MESSAGE, MOTION_GROUP, PIDE_AUTOTUNE, SERIAL_PORT_CONTROL, SFC_STEP.
- Added support for predefined types: ALARM_ANALOG, ALARM_DIGITAL, AXIS_GENERIC_DRIVE, CONNECTION_STATUS, DIVERSE_INPUT, EMERGENCY_STOP, ENABLE_PENDANT, FIVE_POS_MODE_SELECTOR, LIGHT_CURTAIN, PHASE, PHASE_INSTRUCTION, REDUNDANT_INPUT, REDUNDANT_OUTPUT, TWO_HAND_RUN_STATION.
- Added Auto Tag Generation support for Add-On Instruction definitions via L5K (offline).

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.

Allen-Bradley ControlLogix (V4.102.170)

- Fixed Logix project synchronization issue when changing a Device's ID using the Physical Non-Blocking or Physical Blocking Protocol Types.

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.

Allen-Bradley ControlLogix (V4.101.168)

- Fixed packet sequencing issue that can occur during Logix project uploads when using the Physical Non-Blocking or Physical Blocking Protocol Types.
- Fixed the issue where writing '0' to the '_SET' tag of RTC was incorrectly changing the 'YR' tag of RTC.
- Increased the address range for PLC-5 B,T,C,R,N,F,A,D, and BT files to 2000 elements.
- Fixed event log formatting for Micrologix Function File errors.
- Fixed memory overrun issue that can occur if referencing Logix array blocks of less than 4 bytes. This issue would be seen for Logix arrays of less than 4 SINTs (e.g. BYTEARRAY[3]) and Logix arrays less than 2 INTs (e.g. WORDARRAY[1]). Keep in mind that as items are being added in the QC, the block will grow until all items are added. This implies that the block can at any point in time contain less than 4 bytes total. So this issue is not only possible with tags like BYTEARRAY[3] and WORDARRAY[1], but also for bigger arrays as items are being added.
- Fixed handling of CIP Error 0x08. This error can occur upon rebooting a SoftLogix PC, and previously resulted in unrecoverable communications.

Driver updates below coincide with Server Release V4.201.359 (07/19/06)

Allen-Bradley ControlLogix (V4.101.157)

- Fixed Micrologix Function File Block Write issue when multiple Micrologix devices under a channel have differing Function File Block Write settings. The device with Block Writes enabled may show erroneous behavior.

Driver updates below coincide with Server Release V4.200.353 (03/24/06)

Allen-Bradley ControlLogix (V4.100.151)

- Added Tag Hierarchy Setting to Auto Tag Generation Options. The two selections are Condensed and Expanded (Default and previous group/tag hierarchy).
- Enhanced STRING reads so that the String value is terminated according to the length specified in the .LEN member.
- Added Boolean array support.

Driver updates below coincide with Server Release V4.190.341 (11/23/05)

Allen-Bradley ControlLogix (V4.100.135)

- Updated float arrays to return 0 for any item that contains an invalid IEEE floating point value.
- Added support for MicroLogix 1100.
- Changed default data type (selectable from device property) from Long to Float for new devices.

Driver updates below coincide with Server Release V4.180.338 (8/12/05)

Allen-Bradley ControlLogix (V4.91.130)

- Renamed model "ControlLogix 5550" to "ControlLogix 5500" to better represent the 5500 series of supported ControlLogix CPUs. Previous and current support under this model include: 5550, 5553, 5555, 5561, 5562 and 5563.
- Fixed Physical Blocking read issue for UDT's greater than 65535 bytes in size.
- Fixed issue that could cause an unnecessary "CIP connection timeout" when going from Symbolic Addressing Mode to a Physical Addressing Mode.
- Added Average Device Turn-Around Time (ms) to Performance Statistics. This will aid in gauging how long it takes on average for the PLC to respond to the request.
- Fixed bug that could cause unnecessary "CIP connection timeouts" during auto tag generation and/or project upload.
- Added support for ENI:Micrologix Function Files: RTC, HSC, IOS, CS0 and CS1.
- Fixed ASCII (A File) issue where the last element of an array would always read NULL for arrays of even length size starting at an odd byte offset.

Driver updates below coincide with Server Release V4.160.316 (2/11/05)

Allen-Bradley ControlLogix (V4.80.122)

- Fixed ENI connection issue where upon Ethernet cable disconnection/reconnection, timeouts would occur indefinitely trying to synchronize expected responses with actual responses.
- Fixed ENI connection issue where upon model change from an ENI model that uses connected messaging (ie ENI: ControlLogix) to one that used unconnected messaging (ie ENI: Micrologix).
- Fixed buffer overrun issue encountered when driver receives erroneous data or portions of a data packet. May occur on noisy networks such as those involving radio modems.
- Fixed handling of Encapsulation Error 0x03 which occurs on ENI models if 24 seconds of idle time elapses between requests. Prior to this fix, affected tags would simply be assigned bad quality. With this fix, the error will be handled and tags re-requested.
- Fixed handling of Register Session failure. The same socket would be used in subsequent attempts, requiring a restart of the server or break in connection.

Driver updates below coincide with Server Release V4.142.297 (9/9/04)

Allen-Bradley ControlLogix (V4.74.108)

- Fixed issue with SoftLogix models set to a Physical Addressing mode where CIP Error 0x05 would result from project uploads following a cable reconnect.
- Fixed issue with BOOL reads in Physical Addressing Mode when referenced as a non-Boolean data type (i.e. BOOL @ Word).

Driver updates below coincide with Server Release V4.130.287 (5/28/04)

Allen Bradley ControlLogix (V4.73.103)
