Studio 5000 Environment

The Studio 5000® Engineering and Design Environment combines engineering and design elements into a common environment. The first element in the Studio 5000 environment is the Logix Designer application. The Logix Designer application is the rebranding of RSLogix 5000 software and is the product to program Logix5000 controllers for discrete, process, batch, motion, safety, and drive-based solutions.

The Studio 5000 environment is the foundation for the future of Rockwell Automation® engineering design tools and capabilities. It is the one place for design engineers to develop all elements of their control system.

About This ManualThis publication lists instruction execution time and memory usage information for 1768 CompactLogix™ controllers and 1768 Compact GuardLogix® controllers in RSLogix 5000® software.This file is a subset of 1756-RM087O-EN-P that contains information for all Logix5000® controllers.

Before You BeginBefore you use this publication, consider the following:

We recommend that you use this publication electronically only. A printed version can require a high number of pages based on printer settings.

The execution time and memory use information in this publication are approximations. Actual execution times vary based on project configuration and programming techniques.

When you download your RSLogix 5000 project, the controller optimizes memory usage, which might reduce your calculated memory usage by as much as 10% from the values presented in this file.

Not all instructions apply to all controller catalog numbers. For example, the Safety instructions are used with 1768 Compact GuardLogix controllers only.

IMPORTANTThe Logix5000 controllers listed in this publication use a cache mechanism to enhance the performance of instructions. Actual performance depends on how sequentially the data is laid out and how frequently it is accessed.

Caching has a significant impact on the execution times of bit instructions (XIC, XIO, OTE, OTU, OTL). Logix5000 controllers sometimes execute instructions directly out of cache. At other times, Logix5000 controllers do not execute instructions directly out of cache. For example, instructions may execute based on such functionality as cache swapping.

Execution times are optimal when execution occurs directly out of cache. The times provided in this publication represent optimal times. When your instructions do not execute directly out of cache, you will experience times slower than provided here.

Important User Information

Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (publication SGI-1.1, available from your local Rockwell Automation® sales office or online at http://www.rockwellautomation.com/literature) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment.

The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and diagrams.

No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software described in this manual.

Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell Automation, Inc. is prohibited.

Design Considerations

Design Considerations - 1768 CompactLogix, 1768 Compact GuardLogix

Array SubscriptsExample

When an array uses a tag for one of its subscripts, additional memory and execution time is required, depending on the number of dimensions in the array. Keep in mind that memory use and execution time for an instruction increases for each parameter that references an array.

If you use multiple dimensional arrays in a instruction, account for the additional memory and time for each array reference.

The controller operates on 32-bit data structures. If you use a tag other than a DINT to reference a position in an array, be sure to account for the additional time for the data conversion as well as memory and time for using a tag as an index.

If you use an expression in the index, additional memory and time is used for the operators. The additional memory and time depends on the type of operator.

Data ConversionsExample

If you use a data type that is not an optimal data type or if you mix data types, you must account for the additional memory and execution time for data conversion.

If you mix integers and REALs in an instruction, the controller converts the values to REALs and then back to the destination data type.

ExpressionsExample

If an instruction contains an expression (CMP, CPT, FAL, FSC), then add memory and time for each operator in the expression. For each operator, use the values for the corresponding instruction from the "Ladder Instructions" tab. Keep in mind that data type conversions will take place if different or non 32 bit data types are used.

Function BlockExample

When using Function Block instructions, remember to include the time for IREF, OREF, and/or the WIRE when estimating execution time.

Structured TextExample

When using Structured Text, keep in mind that the number and complexity of the assignments, instructions, and comments included in the construct increases the memory and execution time that is required.

About This ManualThis publication lists instruction execution time and memory usage information for 1769 CompactLogix™ controllers with RSLogix 5000® projects. Controller/programming software compatibility varies based on controller catalog number. For information on compatibility, see the controller documentation.This file is a subset of 1756-RM087O-EN-P that contains information for all Logix5000™ controllers.









Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (publication SGI-1.1, available from your local Rockwell Automation® sales office or online at http://www.rockwellautomation.com/literature) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.

About This ManualThis publication lists instruction execution time and memory usage information for CompactLogix™ 5370 controllers in RSLogix 5000® software or Studio 5000 Logix Designer® application projects.This file is a subset of 1756-RM087O-EN-P that contains information for all Logix5000™ controllers.





Not all instructions are used with all controllers. Only some CompactLogix 5370 controllers support Integrated Motion over an EtherNet/IP™ network. Motion content that includes the CompactLogix 5370 controllers only applies to the 1769-L18ERM-BB1B, 1769-L27ERM-QBFC1B, 1769-L30ERM, 1769-L33ERM, and 1769-L36ERM controllers.





Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (publication SGI-1.1, available from your local Rockwell Automation sales office or online at http://www.rockwellautomation.com/literature) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.
