Wiring WARNING In order to prevent danger to humans or the environment, you must not under any circumstances override safety functions or implement measures that cause safety functions to be bypassed or result in the bypassing of safety functions. The manufacturer is not liable for the consequences of such manipulations or for damage resulting from a failure to heed this warning.

(230 V AC --> 24 V DC) with a power loss ride-through of at least 20 ms can be used. The latest information about PS components can be accessed on the Internet at: https://mall.ad.siemens.com These requirements also apply to power packs or power supplies not produced in ET 200pro or S7-300/400 designs.

Page 30: Requirements For Sensors And Actuators
Wiring 4.4 Requirements for Sensors and Actuators Note Note that replacing fail-safe modules in ET 200pro during operation will generate a communication error in the F-CPU. You must acknowledge the communication error in your safety program (for information about F-system behavior after communication errors, fail-safe value output and user S7 Distributed Safety, Configuring and Programming acknowledgment, refer to the manual).
Page 31 27 ms Reliable Detection By the Safety Program in the F-CPU For information about the times for proper detection of sensor signals in the safety program, "Fail-Safe Modules" Safety Engineering in SIMATIC S7 refer to in the system description. Additional Requirements for Sensors General rule: A single-channel sensor is sufficient to achieve SIL2/Category 3.
Page 32 Wiring 4.4 Requirements for Sensors and Actuators WARNING If the actuators are operated at voltages greater than 24 V DC (for example, 230 V DC) or if the actuators switch higher voltages, safe isolation must be ensured between the outputs of a fail-safe output module and the components conducting the higher voltage (in accordance with EN 50178).
Page 33: Diagnostics
Diagnostics 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. Note For digital F-modules, this safe state is the value "0". This applies to both sensors and actuators.
Page 34 Diagnostics 5.1 Reactions to Faults Fail-Safe Value Output for Fail-Safe Modules In the case of F-DI modules, if channels are passivated, the F-system provides fail-safe values for the safety program instead of the process data pending at the fail-safe inputs: ●...

Page 36 Diagnostics 5.2 Error Diagnostics Diagnostics Using LED Display Every fail-safe connection module indicates faults via its channel LED and SF LED (group fault LED). The channel LED and SF LED turn red as soon as a diagnostic function is triggered by the F-module.
Page 37 Diagnostics 5.2 Error Diagnostics Note Channel-specific diagnostics are always updated as far as the current diagnostic function in the diagnostic frame. Subsequent, older diagnostic functions are not deleted. STEP 7 Remedy: Evaluate the valid current length of the diagnostic frame in using the RET_VAL parameter of SFC 13.
Page 38 Diagnostics 5.2 Error Diagnostics Behavior of F-Modules When a Module Failure Occurs In the event of a fatal internal fault in the F-module resulting in failure of the F-module, the following occur: ● The connection to the backplane bus is interrupted and the fail-safe inputs and outputs are passivated.

Page 159: Switching Of Loads
Switching of Loads Switching of Capacitive Loads Switching of Capacitive Loads If the electronic outputs of the 4/8 F-DI/4F-DO DC24V/2A PROFIsafe electronic module are interconnected with loads that draw little current and have capacitance, the "short circuit" error message can result. Reason: capacitances are not sufficiently discharged within the assigned readback time during the self-test.
Page 160 Switching of Loads E.1 Switching of Capacitive Loads Remedy: 1. Determine the load current and capacitance of the load. 2. Determine the operating point in the figure above. 3. If the operating point is above the curve, you must increase the load current until the new operating point is below the curve by connecting a resistor in parallel.

Page 163: Glossary
Glossary 1oo1 evaluation Type of -> sensor evaluation – 1oo1 evaluation is a type of sensor evaluation in which a non- redundant -> sensor is connected to the F-module via one channel. 1oo1 Evaluation -> 1oo1 Evaluation 1oo2 evaluation Type of -> sensor evaluation – In 1oo2 evaluation, two input channels are occupied, either by one two-channel sensor or two one-channel sensors.
Page 164 Glossary Availability Availability is the probability that a system is functional at a specific point in time. It can be increased by redundancy, for example, by using multiple -> sensors at the same measuring point. Backplane Bus The backplane bus is a serial data bus via which the IM 154 interface module communicates with the electronic modules/motor starters and the necessary voltage is supplied.
Page 165 Glossary CRC Signature The validity of the process data in the safety message frame, the accuracy of the assigned address references and the safety-relevant parameters are ensured by means of a CRC signature contained in the safety message frame. Dark Period Dark periods occur during switch-off tests and during complete bit pattern tests.

Page 168 Glossary Process Image The process image is a component of the system memory of the CPU. At the beginning of the cyclic program, the signal states of the inputs are transferred to the process input image. At the end of the cyclic program, the process output image is transferred as a signal state to the outputs.

PROFINET IO controller with assigned PROFINET IO devices PROFIsafe PROFIsafe is the safety-related PROFIBUS DP/PA bus profile for communication between the ->...
Page 170 Glossary Response Time The response time is the time between detection of an input signal and a change in the gated output signal. The actual response time lies somewhere between a minimum and maximum response time. The maximum response time must always be anticipated when configuring a system. For fail-safe digital inputs: The response time is the time between a signal change at the digital input and safe loading of the ->...
Page 171 Glossary Safety-Related Communication Safety-related communication is used to exchange fail-safe data. Sensor Evaluation There are two types of sensor evaluation: -> 1oo1 evaluation - Sensor signal is read in once. -> 1oo2 evaluation - Sensor signal is read in twice from the same F-module and compared internally.
