Issue/Enhancement/Fix
|
|
.223
|
-Fixed demo mode operation for projects that contain drivers that support an unsolicited mode of
operation. These driver will now timeout in their demo mode in the same way other drivers operate.
-This release now support direct access to TOP Server for Intellution users. The Intellution
native driver interface is now built into the TOP Server, therefore the OPC Power tool from Intellution is no longer needed.
|
|
.222
|
- Reworked help system to default to .chm rather than legacy .hlp files.
- Modified how we
launch .chm help files so that the main server window can receive the focus while the help file is displayed.
|
|
.221
|
- Fixed TAPI issue regarding clients attempting to open a line that has not been previously
closed. The server will close the line and re-open on the clients behalf rather than failing.
- Fixed lockup that could occur when a client loads a project through the IPersistFile interface.
|
|
.220
|
- Fixed issue with rejecting all client connection request if an IPersistFile::Load operation failed.
|
|
.219
|
- The OPC layer no longer affects the quality of active items when the group update rate is
modified. The result is that any reads from cache during the period of changing scan rates at the device layer will return the last known value, timestamp and now quality.
|
|
.218
|
- Fixed canonical datatype return when the OPC layer coerces the data type on behalf of the
driver. Previously the canonical type was returned as the type the driver returns to the OPC layer. This should actually have been the type the OPC layer returns to the client.
|
OPC Quick Client Updates:
|
.78
|
- Fixed dialog help to point to the overriden WinHelp so it can determine whether or not to use .chm, etc...
|
|
.77
|
- Reworked help system to default to .chm rather than legacy .hlp files.
|
|
.76
|
- Allow user to save their project when the demo period expires after the 2 hour limitation.
|
Driver Updates:
|
Allen-Bradley ControlLogix
(4.41.57)
|
- Fixed data coercing bug in which bits could not be referenced for non-BITARRAY elements (ie.
DINTARRAY[0]). Symptoms: Tags would be deactivated and error posted: "Datatype 'Boolean' is illegal for this tag."
Boolean is considered an invalid data type for
non-BITARRAY elements (ie. DINTARRAY[0]) and is only valid for BITARRAY elements. Bits within a non-BITARRAY element (ie. DINTARRAY[0].0) are valid and must be Boolean.
|
|
Mitsuibishi Ethernet
(4.21.21)
|
- Added string support.
|
|
Modbus Ethernet
(4.44.32)
|
- Fixed issue with writes to output coils. When writting 1 to an output coil, which already has
value of 1, client may see value as 0 until next read. This was a memory map issue - correct data was sent to device.
- Enabled initial memory map allocation feature.
|
|
Omron Host Link
(4.30.45)
|
- Added open addressing model.
|
|
Siemens 3964R
(4.10.20)
|
- "String Options" device property and wizard page was incorrectly linked to
"Protocol Options" help topic.
|
|
UCON (User Configurable Driver) (4.00.47)
|
- Rebuilt with latest keplib/modem updates.
- Added additional optimization of unsolcited tag update rate. Previous optimization could be partially defeated when multiple unsolicited channels were used.
- Modified tag update logic. Clients were seeing sluggish tag updates for block tags in solicited mode, and for all tags in unsolicited mode. - Bug fix: Fixed length strings, and other formats
with variable length option, would get changed to zero if an attempt to update tag from an unitialized scratch buffer was made.
|
|
Wago Ethernet
(4.01.26)
|
- Fixed issue with writes to output coils. When writting 1 to an output coil, which already has
value of 1, client may see value as 0 until next read. This was a memory map issue - correct data was sent to device.
- Enabled initial memory map allocation feature.
|
|
Yaskawa MP Ethernet
(4.00.05)
|
- Corrected potential issue with multiple bit within word writes to inactive tags.
|
|
Yokogawa DXP
(4.00.05)
|
- Modified login procedure for new Yokogawa DXP Style 4 firmware. Added "User ID" entry
to Device Configuration.
- Also fixed issue that surfaced with Style 4 device concerning CD data reads. When Nak returned in response to CMCXX? query, the driver has timeout error instead of
trapping NAK error. (Became evident in Style 4 where login with 'monitor' function instead of 'user' level prohibits any access to CD data. Style 4 firmware then would be ideally
supported by invalidating CD tags, but retained in autogen and address validation for backwards compat. to Style 2.)
