This version is capable of handling the following new features: - PR1710, PR1711, PR1720 - ew30dll.dll .added checking of (com)port-namelen to be <=32 chars - ewdlgDlg.cpp V1,1,0,3 .changed max comport-namelen to 32 - pr1791.exe V8,0,0,1 .changed default message timeout for topic definition dialog from 3000 to 5000 msec (default setting for new topics) .now really use the Protocol Tick timer from DDE Server settings dialog.

This problem only occurs with internal phases (that do spont. updates) only. Problem details: The setpoint poke was sent to PR1730 and then all spont. messages are ignored until the 'q' to the poke arrived. The problem was that the spont. update arrived before the the poke-'q'. Thus it was locked out and the new value not sent to the clients. Solved by writing the last poked value to ptReadValue after the last poke completed and then passing it to the clients. README.TXT for PR1791 Changes in Version 7008 - PokeFifo size increased to 500 Now up to 500 pokes are buffered (was 50). This only buffers the pokes: an app may generate more pokes in a short time. The over-all poke performance is not increased since it is bound to transfer bandwith which is physically limited ! - problems with PR1781 Initialize/Download solved - !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Due to a fault in WW provided code accessing an item with illegal name that is rejected by the server produces 'dead' undeleteable points in the server ! This means: - After an illegal item has been rejected by the server the server's Configur\Topic Definition menu will be prefaced by an error message. - Also PR1781 won't be able to initialize the server - The server will never stop communication with the topic, even if all clients are closed - The server will accumulate all items that have ever been used. Since the number of items is limited, sometimes it will not accept new items. Workaround: Never access illegal items ! README.TXT for PR1791 Version 7004 - ewdlg.exe again in the package. installed to PR1791's exe directory - !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Due to a problem with the Wonderware SuiteLink server software the following error messages when running InBatch may occur in WWLogger: ".... 2nd dosing phase on one weighingpoint not allowed." ".... Starting a phase a second time is forbidden." The workaround for PR1730 devices is using the firmware version 1730/01 Rel. 1.2 The messages will still appear, but the former false dosing behaviour has been fixed to catch the WW fault in this version. README.TXT for PR1791 Version 7002 - This Version supports the Wonderware SuiteLink protocol of the Factory Suite 2000 package. - a problem with item names beginning with 'm' has been fixed: ALL types of items may have names beginning with 'm' - SPM item names may be made up of uppercase letters as weel, earlier version supported lower case only. e.g. mX1024 mx1024 Mx1024 MX1024 refer to the same bit data in PR1730's SPM at address 1024 - the debug messages for block poll telegrams have been enhanced to print not only hex data but also block address and length - 'lsi' error replies for non-existing weighingpoints are now recognized, logged and handeld properly - msvcrtd.dll now contained in distribution
