5.2.1 Module error If a module error is detected, the SFB-EC responds as follows: − The SFB is completely passivated, i.e. all 8 device ports are passivated. All input and output data are set to "0".
Page 89
The system reacts according to the responses defined in the FSoE specification. In the event of an error in the safety related communication, all input and output data of the SFB-EC are set to "0" and the module remains passivated until the error in the communication has been corrected.
Page 90
5.3 Acknowledgement corrected faults 5.3.1 Acknowledgement module faults If a module error is detected, all device ports are passivated. (Refer to chapter 5.2.1) An acknowledge request is sent when the detected module fault is removed and when no further module fault is detected. Acknowledgement Request: (Request acknowledgement - Module 2 (Functional Data), refer to chapter 4.3.1)
Page 91
Acknowledgement with global acknowledgement pulse The real acknowledgement is done via an acknowledgement pulse of 500 ms (+/- 150 ms) which is sent from the PLC to the SFB-EC. The pulse always globally acknowledges all removed module faults and device port faults ! Faults that have not yet been removed are not acknowledged.
