  • Page 38 Circuit diagram example 4.4 TIA Portal configuration In the 1oo2 evaluation, equivalent both inputs of the safe AS-i slave are occupied, either by a 2-channel encoder or by two single-channel encoders. The two single-channel sensors then belong together functionally as a pair, e.g. two position switches of one door monitoring. The input signals are compared internally for equivalence.
  • Page 39 Circuit diagram example 4.4 TIA Portal configuration The safe monitoring of the position switch is then configured as follows. The explanation of the individual parameters can be found in Section 4.4.5 (Page 36). A 1oo1 evaluation is selected to monitor the position switch because the switch used (version 3SF13 ... 1BA4) is already monitored for discrepancy (see Section 4.2.3 (Page 25)).

    Circuit diagram example 4.4 TIA Portal configuration 4.4.9 Teaching ASIsafe code sequences To perform safety-related communication, each safe AS-i input slave sends a code sequence over the AS-i bus. To prevent a mix-up of AS-i input slaves on the AS-i bus, each AS-i input slave sends a different code sequence.

To do this, follow the steps in Section 4.4.8. (Page 44) Note Since the PROFIsafe address is stored in the electronic coding element of the ET 200SP slot, this step is only necessary if a PROFIsafe address is missing, or if a different one was assigned.
