RSLogix 500™
Programming for SLC 500™ and MicroLogix™ Families

What's New in Version 5.50.00?

5 August, 2002

Updating RSLogix 500  |  Current Enhancements  |  Current Repairs   |  Known Anomalies  |  Caveats   

IMPORTANT ALL Users!- Effective with this release V5.50, RSLogix 500 no longer supports operation on workstations running Microsoft Windows 95™ operating system. RSLogix 500 is supported on workstations running Microsoft Windows 98™, Windows ME™, Windows NT 4.0™ SP6a and greater, Windows 2000™ or Windows XP™ operating system.

IMPORTANT ALL USERS! RSLogix 500 r4.10.00 may display online data inconsistently under certain circumstances.  The online circumstances which may cause this behavior are having multiple ladder views open, viewing large rungs with many different addresses, CDM's, formatted Status views or PID status screens.  This has been fixed in r4.10.01 and later.

IMPORTANT ALL USERS!   When you accept an online edit in RSLogix 500 in version 3.01.09 or later, the data associated with the rung (i.e. Pre and Acc values for TON and etc.) is transmitted to the processor.  The data sent to the processor may be out-of-date.  When you begin an online edit, RSLogix 500 caches the values associated with the rung you are editing.  Upon acceptance of the online edit the cached data is sent to the processor.  This may affect your application program in ways you did not anticipate.  RSLogix 500 r3.01.02 and r3.01.07 did not transmit any of the data to your processor.  This resulted in many of you experiencing problems with online editing.  Versions of RSLogix 500 released before r3.01.02 operate the same as r3.01.09 does, RSLogix 500 r3.01.09 restores this pre r3.01.02 functionality.

IMPORTANT MICROLOGIX 1500 PROCESSOR USERS! If you are using the Data File Download Protection feature please read this advisory regarding RSLogix 500 r3.01.02.  When using r3.01.02 if you upload a MicroLogix 1500 application program that uses the data file download protection feature and you do not have a copy of the original RSS file on the computer, the upload process will corrupt the program file entering computer memory.  CRITICALLY IMPORTANT, if you have uploaded a program under these circumstances and have downloaded or saved the project your only recourse is to visually compare the project against a known good print-out, download a known good project file, or clear processor memory and re-enter your application program.

All Users!
RSLogix 500 r4.50.00 requires that you update to RSLinx™ 2.00.175 or later for Windows NT™4.0 sp4, Windows 95™, Windows 98™, Windows 2000™ or Windows XP™.

To Update Release 2.00 or later         [goto Top]
Prior to installing RSLogix 500 V5.00 you must uninstall the previous version, using Add/Remove Programs in Control Panel. The same is true if you wish to reinstall V4.50, you must first uninstall the previous version, using Add/Remove Programs in Control Panel.

To update to RSLogix 500 r5.00.xx simply insert the CD into your CDRom drive to initiate the autorun menu.  If you are not using the autorun menu, run SETUP.EXE found on the CD in \RSLogix_En\Disk1.  The default install path is "C:\Program Files\Rockwell Software\RSLogix 500 English". The language suffix changes for the different languages supported by RSLogix 500. You can change the path. Please note that the "RSLogix 500 English" portion of the path is fixed and cannot be altered. Once you have installed the software please remember to move your existing project files if necessary to the new project directory.

The following list of enhancements was introduced as part of release 3.01.07 

• Added support for the MicroLogix 1500 processor family 
• Added support for SLC 500 5/05 processor EPIC-style messaging 
• Added support for RSLogix symbols and address descriptions to the SLC library function.   This support prevents any truncation from occurring when reusing the library with RSLogix.  When saving a SLC library file intended for reuse with A.I. Series PLC500 software, address description lines containing more than 15 characters OR symbols longer than 15 characters are truncated to match the A.I. Series PLC 500 programming software address description and symbol length. You can prevent this truncation by limiting the length of symbols and address description lines from the Tools>Options dialog. 
• Added a User Workspace that permits you to save the current views and window positions in a named file.  You can save multiple workspaces as part of a RSLogix project. 
• You can customize report page header and footer, and the text that appears on the report title page. 
• Added an Instruction Palette button to the toolbar allowing you to use a toolbar containing all instructions. 
• Added the ability to copy/paste (drag-and-drop) rungs while online in Remote Run.

• Added support for the SLC 500 5/05 processor remote MSG capability 
• You can use ASCII Library import and export (.SLC files) 
• Added support for the assignment of Timer, Counter, and Control element symbols as the base symbol for the subelements and bits. This emulates an A.I. Series feature. Existing symbols assigned to subelement or bits of Timer, Counter, or Control elements are not removed. Symbols assigned to the subelements or bits of Timer, Counter, or Control elements take precedence and are displayed before the base symbol. 
• Augmented the project organizer to include links to the RSLogix 500 help files. 
• Added a help file that contains keyboard shortcuts to accelerate your use of RSLogix 500. 
• You can specify a range on rungs within a program file for reporting. 
• Cross-reference has been added to the ladder display and reporting. 
• You can set the starting page number of a report. This setting only impacts the hardcopy. 
• You can control Report properties separately from the View properties. 
• Enhanced drag-and-drop editing of addresses, instructions, and rungs to include symbols and address comments when dragging between instances of RSLogix 500, or to RSLogix 5.

The following list of enhancements was introduced as part of release 2.10 

• A histogram feature was added under COMMS>HISTOGRAM to assist with your troubleshooting efforts. 
• The SLC 5/05 Ethernet processors are supported. 
• The MicroLogix 1000 with Analog controllers are supported. 
• The node address in the message (MSG) instruction allows nodes to be addressed from 0 -255 to more completely support DF1 serial communications.

The following list of enhancements was introduced as part of release 2.00. 

• RSLogix 500 installation now includes an uninstall feature. 
• When opening a projectname.ACH file RSLogix 500 always converts it to the RSS format. If you subsequently close the file, download, or go on-line you will be prompted to save the file. This will create a new projectname.RSS file, by default. RSLogix 500 can still save your project to the ACH file format using File, Save As. 
• Added support for the MicroLogix 1000 Series D controllers that support Half-duplex DF1 Slave communications. 
• Enhanced the File>New dialog allowing you to set default communication parameters and project name. 
• Enhanced the File>Open allowing you to view project revision notes before you open a project 
• The project file projectname.RSS contains all database and project related files. If you need to share a project with someone simply provide them with the projectname.RSS file and they will receive all project related information. When sharing RSLogix database information with other RSI applications, like RSView 32, you must use the Save database as external file checkbox on the File>Save As dialog to make the database file available to that application. 
• The projectname.RSS file contains both an on-line and off-line image of your project. This speeds the process of connecting to a controller. The images can get unsynchronized if you don't save your changes when going from on-line to off-line. To synchronize the images you must download, upload or save the project while on-line. 
• A new Auto-recovery feature detects the presence of your autosave file in the event of a system crash, GPF, or power failure and allows you to automatically open the autosave file retaining all your edits since the last autosave. 
• Added symbol, address and instruction comment description lengths to the Tools>Options dialog. This allows you set limits that ensure database compatibility with RSI's legacy DOS products. This feature only affects projects created with RSLogix 500 r2.0 and later. Existing project databases are not converted to comply with new settings you make. 
• A new Online edit toolbar was added to the Ladder view to improve access to the on-line edit commands 
• Added the ability to adjust report margins. 
• Program files marked debug for use with RSLogix Emulate 500 are removed from the project tree when the project execution is monitored online with a SLC 500 processor. They will appear when monitoring execution of the project online with the emulator. 
• Simplified the configuration of communication parameters for a project so that it is less confusing. 
• Simplified the Read I/O Configuration feature so changes in the communication parameters to read the I/O configuration of a processor do not effect the communication settings for the current project. 
• Disabled toolbar customization feature due to problems within Microsoft Foundation Class resources. This feature shall be available in a future release. During installation your currently configured toolbars shall be removed and replaced with the default toolbar configuration. 
• Forced the Address/Symbol editor to follow the bit addressing display mode used in the ladder editor for I/O and Binary addresses. 
• Configuration dialogs were added for the following I/O modules: 1746-QV and 1203-SM1 (Enhanced mode only)

Known Anomalies           [goto Top]
The following is a list of known anomalies at the time the software was shipped to you. 

• Math instructions that include integer or floating point constant operands and specify a long integer destination, will return an "Operand sizes to not match" error.  To work around this put the constant in a data file.
• In the Channel 1 configuration for an SLC 5/05 Ethernet processor, there is an IP address entry for a Secondary Name Server.  This IP address is not being saved properly in the SLC 5/05.  The only way to currently set the Secondary Name Server value is via Bootp. This will be fixed in the next firmware release.
• Printing RSLogix reports on some printers that have non-standard character resolutions will result in the header and footer appearing very large.   An example of a printer exhibiting this characteristic is the OKIDATA 320IBM.
• You cannot rebuild the current projects database if the project has been opened from a network server. 
• When importing a native RSLogix 500 database in to a project program and data file names and descriptions will not be imported. 
• You cannot replace an indexed instruction parameter with a non-indexed instruction parameter, eg replace #N7;0 with N7;10. 
• If you do not see tooltips when idling your mouse on a RSLogix 500 component you need to check the version of the COMCTL32.DLL file. You must have version 4.70 or later. This is a non-redistributable Microsoft DLL. This means RSI cannot ship the correct version with our product). It is distributed with Internet Explorer 3.0. 
• The wildcard character "?" can only be used to perform digit matching. 
• When importing an APS documentation database into a project created with RSLogix 500 you must first delete the existing RSLogix 500 documentation database.

Restrictions and Non-operational Functions         [goto Top]
The following is a list of features and functions that are not fully implemented or non-functional at the time the software was shipped to you.

• It is no longer possible to provide the floppy disk image of the software due to size and install tool limitations. It is possible to create the floppy image from the CD image with WinZip and the floppy media if you so wish.
• The RSLogix description database can accommodate up to 64K descriptions, when running under the Win 9X environments.  Saving projects with description databases over this limit under Win 9X will corrupt the database. This limitation is not present when running under Win NT or Win 2K.
• If you are using RSLinx to perform DDE communications with a processor and you download a project to the same processor the download may fail. If this occurs the processor loads its default program. To avoid this situation you should cease DDE communications to your target processor when you plan to download a project to the same processor.
• A firmware change in the implementation of the MSG instruction between the OS500 and OS501 SLC 5/05 processors requires that you delete and re-enter all MSG instructions in any SLC 5/05 programs created with RSLogix 500 r2.10.12.  
• The project file projectname.RSS contains all database and project related files. If you need to share a project with someone simply provide them with the projectname.RSS file and they will receive all project related information. When sharing RSLogix database information with other RSI applications, like RSView 32, you must use the Save database as external file checkbox on the File>Save As dialog to make the database file available to that application. 
• The projectname.RSS file contains both an on-line and off-line image of your project. This speeds the process of connecting to a processor. These images can get unsynchronized, this occurs if you don't save your changes when going from on-line to off-line. To synchronize the images you must download, upload or save the project while on-line.
• If you install multiple localized versions of RSLogix 500 (English, French, German, Italian, Spanish, or Portuguese) on the same computer, the order in which you install the applications may impact the embedded application text strings you are viewing.   Rockwell Software recommends installing your primary language last. 
• RSLogix 500 prints Ladder Logic reports as graphic files.  The ladder report cannot be printed to a text file.  Other RSLogix 500 reports can be printed to a text file using the Generic/ Text-only printer driver in Windows.  
• The following characters may not be used in RSLogix 500 symbols, ` ~!@#$%^&*()-+={}[]|\\:;""'<>?,./ .  If you have used these characters in a previous release of RSLogix 500 the symbols will appear in your ladder views and reports.  However, you cannot modify the symbol.
  We recommend that you export the database to the ASCII CSV format to speed the replacement of the illegal characters in your symbols.

Start-up Problems
