Anomalies for Studio 5000 Logix Emulate version 33.00

The following list identifies the anomalies corrected in Studio 5000 Logix Emulate version 33.00 and the known anomalies found during testing for this release. Use the identification information provided in the brackets [] to track the anomaly in future releases or contact Customer Support for assistance with a related issue.

• Reopening the chassis monitor or re-adding an emulated controller changes the battery LED to red and loses the controller application. [Lgx00190098]
• Starting the chassis monitor without administrative rights while running Studio 5000 Logix Emulate as an administrator is not supported. By default, Studio 5000 Logix Emulate installs with Run as administrator selected. [Lgx00219241]    
• Operation of binary parameters is not handled properly for the MAG, MAS, and MRP instructions.  These parameters are incorrectly driven by the values of other instruction operands. [Lgx00199947].
• Restoring a snapshot created from the chassis monitor with All Modules > Save Snapshot originally created with versions 31 or 32 would not allow those versions to be selected for Restore. [Lgx00221759]
• The Chassis Monitor becomes unresponsive when saving a snapshot of an Emulate OTS controller. [Lgx00221761]
• Stopping and restarting the chassis monitor when the OTS controller is running causes a battery fault on the associated faceplate. [Lgx00225886]
• Sending values from a user application to an input image in an OTS controller with RA_ExecuteTagGroup() causes the values to be applied inaccurately. [Lgx00194650]
• Restoring a snapshot with All Modules > Restore may trigger a controller red x error. [Lgx00227339]
• No interface is available to programmatically download a project to an OTS controller. [Lgx00179176]
• Emulate controller becomes unresponsive instead of declaring a watchdog fault. [Lgx00228487]
• Certain message instructions would occasionally result in a controller with a red x. [Lgx00229181]
• When using the RA_TriggerRunPulse() programmatic interface to an OTS controller, an incorrect error triggers if the controller is not halted. [Lgx00229372]
• An error occurs when downloading an .acd file to the Emulator controller and the destination operand is a REAL data type for Logical operations. Project verification does not identify the error. [Lgx00217681]
• Using Studio 5000 Logix Emulate operation of binary parameters is not handled properly for the MAG, MAS, and MRP instructions. These parameters are incorrectly driven by the values of other instruction operands. [Lgx00219085]
• Using Studio 5000 Logix Emulate CTU behavior was incorrect for prescan. [Lgx00219605]
• Convert to BCD (TOD) and Convert to Integer (FRD) does not generate correct results when using Studio 5000 Logix Emulate. [Lgx00218808]
• Installing a personalized version of Studio 5000 Logix Emulate triggers a EULA.text is missing error. [Lgx00230711]

• An anomaly exists in Studio 5000 Logix Emulate controllers when using the Jump to Subroutine (JSR) instruction with Return (RET) instruction parameters in the Sequential Function Chart [SFC] programming language. [Lgx00155841] To resolve this issue, avoid using RET with SFC subroutines. Use alternate languages such as Ladder, Structured Text, or Function Block.
  
• The result of the ADD instruction in SFC is different than the other languages. It is also different from a physical controller. [Lgx00156771] To resolve this issue, avoid using ADD instructions with SFC subroutines. Use alternate languages such as Ladder, Structured Text, or Function Block.
• Rockwell Automation recommends not configuring a low Watchdog value for tasks in Emulate because Windows system tasks may preempt user tasks in the Emulate controller. When preemption occurs for a specified duration, a Watchdog fault occurs. Improved watchdog timing does not prevent a watchdog fault for low watchdog values. [Lgx00219641]

Studio 5000 Logix Emulate version 33.00 has the following functional changes since the last release:

• Implemented restoring a user program using All Modules > Restore to prevent restarting the chassis monitor. During restore, the chassis monitor blinks the green battery LED.

The following are the application notes for Studio 5000 Logix Emulate version 33.00.

Limitations

• While the Windows 10 operating systems run on many touch-enabled devices, various features of the Studio 5000 Logix Emulate application might not be touch-enabled. Most functions are expected to work with touch, but the software is tested only with a keyboard and a mouse.
• Running Studio 5000 Logix Emulate in conjunction with Fast-User Switching is not supported. Running Studio 5000 Logix Emulate software in Safe mode is not supported. Accessing Studio 5000 Logix Emulate through Remote Desktop on remote machines is not tested.
• Licensed-Based Source Protection is not supported. License-Based Source Protection controls permissions (Use, View, Edit, Copy, Export, and Protect) on license-protected Add-On Instructions and routines.

Performance

• Do not depend on the emulated controller to match the performance or operation of the physical controller. Some instructions are interpreted differently in an emulated controller than in a physical controller. Execution times for instructions and program files may be significantly different in an emulated controller than in a physical controller.

Studio 5000 Logix Emulate controller restrictions

• For maximum portability across platforms, avoid mixed operand types between the destination and its inputs. To get identical results for similar operations across languages, perform floating point operations. Floating point operations can affect performance. Verify that operands are compatible with the I/O.
• There are instruction differences across programming languages and Logix platforms. The following examples use the operation i = n / m where all the operands are integers. Ladder DIV instructions perform an integer divide operation and store the immediate result in the destination. For ‘n’ = 800 and ‘m’ = 1000, ‘i’ is equal to 0. The DIV function block instructions only does floating point operation. The Function Block instruction converts the inputs to reals, if necessary, and converts the result from a real to the destination type, if necessary. In this example, ‘n’ is converted to 800.0 and ‘m’ is converted to 1000.0. The result of the operation is 0.8. That result gets converted to an integer where rounding rules apply and the final destination value is 1. This difference between Ladder and Function Block instructions applies to all Logix platforms. Function Block instructions only perform floating point operations.
• If a Studio 5000 Logix Emulate controller experiences repeated minor faults, a red X appears. This occurs in systems where minor faults generate repeatedly on each program scan. To avoid this, correct any programs that may cause repeated minor faults.

Use with FactoryTalk Linx

• To use FactoryTalk Linx with Studio 5000 Logix Emulate, select Tools > Options > Application and clear Enable Large Connection for Download. 

Enable remote connections

Studio 5000 Logix Emulate requires an upgrade to RSLinx Classic Gateway version 4.20. If RSLinx Classic Lite is installed, uninstall <RSLIC? Lite and install RSLinx Classic Gateway version 4.20. Remote connections are disabled when both FactoryTalk Linx and RSLinx Classic version 4.20 are installed.

To enable remote connections when using RSLinx Classic version 4.20:

1. Ensure that FactoryTalk Linx is not running. If FactoryTalk Linx is running as a service, stop the service and mark the service for manual startup.
2. In RSLinx Classic Gateway, select View > Options and select Accept UDP messages on Ethernet port.
3. Restart RSLinx Classic.
4. Under Communications, verify that Configure Gateway… is selected.
5. Restart RSLinx Classic.

Tip: After configuring RSLinx Classic, FactoryTalk Linx may be enabled. RSLinx Classic will enable remote connections.

6. In Logix Designer, select Communications > Communications Software > RSLinx Classic.
