  • Page 33: Diagnostics

    Diagnostics Introduction Overview This section provides information on the following topics: • Reactions to faults of the fail-safe I/O module • Diagnostics of the fail-safe I/O module if a fault occurs Reactions to Faults Safe State (Safety Concept) The basic principle behind the safety concept is the existence of a safe state for all process variables.
  • Page 34 Diagnostics Fail-safe Value Output for the Fail-Safe I/O Module For fail-safe input modules, if passivation occurs, the F-system provides fail-safe values for the safety program instead of the process values pending at the fail-safe inputs: • For fail-safe digital input modules, this is always the fail-safe value 0. Depending on which F-system is used and the type of fault that occurred (F-I/O, channel, or communication fault), fail-safe values are used either for the affected channel only or for all channels of the fail-safe I/O module involved.

  • Page 35: Fault Diagnostics

    Diagnostics Fault Diagnostics Definition Diagnostics can be used to determine whether faults occurred during signal acquisition by the fail-safe I/O module. Diagnostic information is assigned either to one channel or to the entire fail-safe I/O module. Diagnostic Functions are not Critical to Safety Diagnostic functions (displays and messages) are not critical to safety and therefore are not designed to be safety-oriented functions.
  • Page 36 Diagnostics Diagnostics by LED Display The fail-safe I/O module indicates faults with its SF LED (group fault LED), for example faults in the internal sensor power supplies. The SF-LED lights up as soon as a diagnostic function is triggered by the fail-safe I/O module.

  • Page 85: Response Times

    Response Times Introduction The response times of ET 200eco fail-safe I/O module are listed below. The response times of the fail-safe I/O module are included in the calculation of F-system response time. You will find information about the calculation of F-system response times in the Safety Engineering in SIMATIC S7 system description.
  • Page 86 Response Times Note The MS Excel files for calculating maximum response times (s7fcotib.xls or s7ftimeb.xls) provided with the S7 Distributed Safety and S7 F/FH Systems optional packages support calculation of the “maximum response time when a fault is present” by increasing the response time by the amount of the parameterized discrepancy time.

  • Page 87: Glossary

    Glossary 1oo1 Evaluation 1oo1 evaluation is a type of sensor evaluation in which one -> sensor is connected to the fail-safe I/O module by means of a single channel. 1oo2 Evaluation -> Sensor evaluation method - In 1oo2 evaluation, two input channels are occupied, either by one 2-channel sensor or two single-channel sensors.
  • Page 88 Glossary Channel Group The channels of a module are grouped together in a channel group. Certain parameters in STEP 7 can only be assigned to channel groups, rather than to individual channels. Channel Number The inputs of an I/O module are identified uniquely by means of the channel number and the channel-specific diagnostic messages are assigned.
  • Page 89 Glossary Discrepancy Time Discrepancy time is a period of time configured for the -> discrepancy analysis. If the discrepancy time is set too high, the times for fault detection and -> fault response are extended unnecessarily. If the discrepancy time is set too low, availability is decreased unnecessarily because a discrepancy error is detected when, in reality, no fault exists.
  • Page 90 Glossary F-I/O F-I/O is a group designation for fail-safe inputs and outputs available in SIMATIC S7 for integration in S7 Distributed Safety and S7 F/FH systems. The following F-I/O modules are available: Fail-safe ET 200eco I/O module • S7-300 fail-safe signal modules (F-SMs) •...
  • Page 91 Glossary Passivation If an -> F-I/O module detects a fault, it switches either the affected channel or all channels to a -> safe state; that is, the channels of the F- I/O module are passivated. The F-I/O signals the detected faults to the CPU.
  • Page 92 Glossary Redundancy, Availability-enhancing redundancy means multiple availability of Availability- components to ensure that components continue to function even in the Enhancing event of hardware faults. Redundancy, Multiple availability of components with the aim of exposing hardware Safety-Enhancing faults based on comparison (for example, -> 1oo2 evaluation in fail-safe signal modules.
  • Page 93 Glossary Safety Integrity The safety integrity level (SIL) is a safety class in accordance with Level IEC 61508 and prEN 50129. The higher the safety integrity level, the stricter the measures must be to prevent and eliminate systematic faults and to remedy hardware failures. With fail-safe ET 200eco I/O modules, safety-integrity levels up to SIL 3 can be achieved in safety mode.
