Original Press Release:
ISaGRAF Version 3.50
The recent release of ISaGRAF 3.50 shows the ISaGRAF team's true will to support and maintain this well known product. As the most used and advanced product in the open process control world, ISaGRAF continues to exist and evolve. More than 240,000 target licenses were sold since the beginning of this product. Its reliability makes that ICS Triplex uses it in their triple modular redundancy (TMR) and safety system.
This year's first release of ISaGRAF 3.50 includes many new features. This latest version offers the features of all previous versions as well as many new features:
o An IEC61131 toolset supporting all IEC61131-3 languages (LD, IL, ST, SFC, and FBD)
o Full compatibility with version 3.3x and later. The ISaGRAF V3.5 Workbench can be used to build programs for download on ISaGRAF 3.3x or later targets.
o The inclusion of all features from the previous ISaGRAF 3.46 such as the many localization languages: English, German, French, Italian, Japanese, Russian, and Chinese
o Full compatibility with projects developed with any previous version from 3.3 or later. The Workbench can load any project built with a previous version of ISaGRAF.
o A trial period without limitation to the number of I/Os for 30 days before requiring licensing
o Licensing available as a software key (Protection Plus) or a hardware key (dongle). You license software keys in ISaGRAF's License Manager.
o Licensing the Workbench for 32, 256, or an unlimited number of I/Os as well as a specific number between 1 and 4095
o Use of the same algorithm as ISaGRAF 4 to implement frequent checking of licensing. This mechanism has been successfully implemented for many years in ISaGRAF 4.
o The possibility for distributors to produce software licensing keys for standard or customized versions of the workbench. Software licensing keys are produced using Trigger code for distributors, available separately from ISaGRAF 3.50.
o The inclusion of the OPC DA 2.0 server, also available at no cost from our web site. This OPC DA 2.0 server can connect with ISaGRAF 3.x or ISaGRAF 4.
o The ability to run the Workbench on the following operating systems: Windows 95, Windows 98SE, Windows NT 4, Windows 2000, and Windows XP
o The ability to follow the logic flow in LD/FBD diagrams during simulation or on-line debugging by making power flows appear highlighted red and blue
o The display of the lock state and actual device values for locked Boolean and analog I/Os. Actual device values include forced values. The lock state of I/Os is displayed in the following editors and tools:
-FBD editor
-Quick LD editor
-Dictionary
-List of variables (spy list)
o The display of variable comments as tool tips throughout a whole diagram, in the Quick LD and FBD/LD editors, while in off-line or on-line mode
o The availablility of a network break function block in the FBD editor
o The preservation of the CRC project file when building a project without any changes. If the application codes and variables of a project do not change, then the CRC of the project remains the same. This feature is very useful for online changes.
