Changes Since 2005
Home ] Up ]

 

The following additions / modifications were performed since 2005 version:

bulletAOT Computation - LMEX load points now do NOT Accumulate Off Time when turned off manually. All other automatic load point operations result in AOT accumulation.
bulletMicrosoft .Net Framework 2.0 -  WebLink and MCSA now run on Version 2.0 of the framework, using ASP. NET 2.0. Numerous internal modifications were needed to compile all the code in the new VS 2005 environment. Some of the previously used functions in C++ and C# have been deprecated, so code had to be rewritten to use the latest APIs.
bulletWebLink E-Mail Handling - was modified to use the latest above mentioned APIs. E-Mail message format can now be selected on address level, as opposed to globally like before. This means that each individual address can have its own individual mail format. For example, a recipient can have three e-mail addresses: one at the office (HTML messages), one at home (ASCII messages), and he / she can also receive SMS messages on his / her cell phone, all at the same time.
bulletSMS Messages - WebLink can now send SMS messages to cell phones via provider's e-mail system. SMS Cell phone address can now be targeted with SMS formatted e-mail messages - ASCII messages not exceeding 160 characters in length.
bulletDNP Driver Modification - Support for objects Group 1 Variation 2, and Group 10 Variation 2 was added. This enables NTMC to poll for status of control point state and record its change of state if reported state conflicts with the state recorded in NTMC database.
bulletProtocol Management by Remote Units - was modified. Each remote unit now supports Native, DNP and MODBUS choices. The last two are always available, and Native is available if protocol is implemented.
bulletTelescada - ATS Protocol - was added. NTMC can now talk to their ATS series of RTUs used in the gas industry. The old Telescada protocol is now called Telescada - ARS protocol.
bulletAnyDATA Modem Support - was added. The modems are used to communicate with devices via cellular networks.
bulletWebLink Object Upload Logging - a switch has been added which can turn off logging of object uploads to server. Default is OFF. Upload failures are still logged.
bulletWebLink Publisher Cosmetic Changes - User name is displayed more prominently than before after successful log-on. The words 'gas' and 'SMS' have been added to the welcome page to reflect newer WebLink / NTMC functionalities.
bulletWebLink Publisher Display of Objects With No Hyperlinks - those objects are no longer displayed. The only objects with no links still allowed to persist are those which are needed to preserve the selector tree structure. Effectively this prevents end users with restricted privileges to see other users' owned system objects. Security previously prevented seeing other users' object contents, now WebLink Publisher does not even list those objects.
bulletAOT Management - Accumulated Off Time of load points is now once again displayed in days - hours - minutes - seconds format. A new dialog screen was designed to allow operators to enter AOT in that same format, instead of seconds as before this change. 
bulletMODBUS Driver Modification - The driver previously expected specified length responses from server. Increased driver versatility no longer allowed this approach, so messages are now handles on real time basis.

The following known problems were corrected since 2005 version:

bulletTimed Control Point Display - displays were incorrect because of some of the recent source code modifications involving remote unit windows in RUEX. 
bulletControl Point Activity Recording - was incorrect in NTMCRDR files. The problem was introduced by recently added source code related to DNP functionality.
bulletLoad Point Frozen Mode - would not persist through system re-start. Mode change would be recorded in memory (object), but was not saved on hard disk. Load point operations mode would come back as 'Auto' after NTMC re-start.
bulletMODBUS Driver Malfunction - the driver would upload data to incorrect register on occasion. The problem was caused by inadvertent interaction with some of the newly added / modified source code. 
bulletRun Time Data Loading - was rewritten. In rare cases of file corruption NTMC would reject the file, and not re-start. New code logs the error, re-initializes run-time data file, and NTMC starts in spite of the problem.
bulletLMEX Load Point List Display - had a problem in one customized version only.
bulletWebLink Manager E-Mail Dispatcher - was not updating watchdog reference counter. WebLink would re-start the main thread if e-mail dispatcher did not return within 90 seconds.
bulletWebLink Manager Event Logging - entries were improperly terminated, so MCEV would not display them correctly. Problem occurred after source code was rewritten to use the new 2.0 API.
bulletLMEX Reporting to WebLink - was modified. LMEX now reports to WebLink load point associated control point state, as opposed to load point state. In case of operation failure in RUEX, load point state revert to previous state. This would cause WebLink to issue unnecessary e-mail messages.
bulletLMEX Load Point List Display - condition could arise where constant list updating ensued, eating up all processor time. A couple of inefficiencies were also corrected.
bulletWindows Socket Layer Interaction with VPNs - single socket 'reads' may come back as multiple messages over VPNs, but not LANs. The driver was modified to handle the situation.
bulletRemote Client Viewing of Log Files - the problem arose when files were full, and number of lines to be read was smaller than maximum lines in the file.
bulletRemote Unit Driver Initialization - data recording I/O point addresses would not properly initialize.
bulletWebLink and MCSA Windows in Minimized State - problem in windows would not allow windows to be set back to normal viewing state if they were minimized when the programs were shut down. WebLink and MCSA work around this problem by not recording window state and location if program window is minimized at the time of shutdown.
bulletMODBUS Driver Problem - In special circumstances, when the driver would attempt to log an error condition, the event log generating code would refer to a non-existent remote unit id, causing RUEX to shut down.
bulletSA206 Switch Driver Would no Longer Load - the problem was corrected.
bulletRemote Unit Resident Data Recording (RURDR) - could no longer be enabled on Telescada RTUs. The problem was introduced when protocol management by remote units was modified earlier this year (see Protocol Management by Remote Units above, on this page). One of low level functions was inadvertently broken. The problem was corrected.
bulletRemote Code Generator (RCG) Board Support - no longer worked. Recent rework of protocol handling introduced a bug preventing RUEX from properly addressing outgoing messages via RTUs equipped with RCG boards. The problem was corrected.
bulletLMEX Screen Updating - LMEX screens would update too often, even when no new data was forthcoming from RUEX. The problem was corrected.
bulletDNP Communications - a bug introduced in earlier revision broke the code so DNP driver could no longer issue control codes and process multi-segment messages. The bug was removed.
