About the Book
This document describes the function blocks FB_PreventaDiag and FB_PreventaMain contained in the PreventaSupport library. FB_PreventaDiag can be used to evaluate the diagnostic output of Preventa XPS safety modules, thus monitoring the device functionality by "translating" the bit sequence into diagnostic code. FB_PreventaMain uses this diagnostic code as input and executes calculations concerning maintenance tasks based on the code.
This document has been updated for the release of EcoStruxureTM Machine Expert V1.1.

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.
Before you attempt to provide a solution (machine or process) for a specific application using the POUs found in the library, you must consider, conduct and complete best practices. These practices include, but are not limited to, risk analysis, functional safety, component compatibility, testing and system validation as they relate to this library.
|
|
|
IMPROPER USE OF PROGRAM ORGANIZATION UNITS |
|
oPerform a safety-related analysis for the application and the devices installed. oEnsure that the Program Organization Units (POUs) are compatible with the devices in the system and have no unintended effects on the proper functioning of the system. oUse appropriate parameters, especially limit values, and observe machine wear and stop behavior. oVerify that the sensors and actuators are compatible with the selected POUs. oThoroughly test all functions during verification and commissioning in all operation modes. oProvide independent methods for critical control functions (emergency stop, conditions for limit values being exceeded, etc.) according to a safety-related analysis, respective rules, and regulations. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
|
|
|
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. |
Care must be taken and provisions made for use of this library for machine control to avoid inadvertent consequences of commanded machine operation, state changes, or alteration of data memory or machine operating elements.
|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
oPlace operator devices of the control system near the machine or in a place where you have full view of the machine. oProtect operator commands against unauthorized access. oIf remote control is a necessary design aspect of the application, ensure that there is a local, competent, and qualified observer present when operating from a remote location. oConfigure and install the Run/Stop input, if so equipped, or, other external means within the application, so that local control over the starting or stopping of the device can be maintained regardless of the remote commands sent to it. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
Update your application program as required, paying particular attention to I/O address adjustments, whenever you modify the hardware configuration. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
