About the Book

Document Scope

This documentation will acquaint you with the High Speed Counter (HSC) functions and variables offered within the M258 controller.

This documentation describes the functions and variables of the M258 HSC library.

In order to use this manual, you must:

oHave a thorough understanding of the M258, including its design, functionality, and implemen­tation within control systems.

oBe proficient in the use of the following IEC 61131-3 PLC programming languages:

oFunction Block Diagram (FBD)

oLadder Diagram (LD)

oStructured Text (ST)

oInstruction List (IL)

oSequential Function Chart (SFC)

Only DM72F• expert module can be used with the M258 HSC library.

LOSS OF CONTROL

oThe designer of any control scheme must consider the potential failure modes of control paths and, for certain critical control functions, provide a means to achieve a safe state during and after a path failure. Examples of critical control functions are emergency stop and overtravel stop, power outage and restart.

oSeparate or redundant control paths must be provided for critical control functions.

oSystem control paths may include communication links. Consideration must be given to the implications of unanticipated transmission delays or failures of the link.

oObserve all accident prevention regulations and local safety guidelines.1

oEach implementation of this equipment must be individually and thoroughly tested for proper operation before being placed into service.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

1 For additional information, refer to NEMA ICS 1.1 (latest edition), "Safety Guidelines for the Application, Installation, and Maintenance of Solid State Control" and to NEMA ICS 7.1 (latest edition), "Safety Standards for Construction and Guide for Selection, Installation and Operation of Adjustable-Speed Drive Systems" or their equivalent governing your particular location.

UNINTENDED EQUIPMENT OPERATION

oOnly use software approved by Schneider Electric for use with this equipment.

oUpdate your application program every time you change the physical hardware configuration.

Failure to follow these instructions can result in death, serious injury, or equipment damage.
