Figure 12: Data Input Voltage Constraints in Safety Mode
As soon as the F-D0* input pad detects an offset level less than V_OFL(Max) the SAP5 resets the data input for
D1 (F-D1*), signalling an OPEN state at the safety switch connected to D0*. The input data for D3 (F-D3*) will
be reset if the F-D2* detects an offset level less than V_OFL(Max), respectively.
Provided that the offset levels are not missing, the E²PROM bits D1* and D3* are transmitted as data bits D1
and D3 if swap_flag = ‘0’, otherwise they are swapped.
In order to avoid desynchronization with the safety monitor in case the AS-i master repeats a DEXG call, the
SAP5 will not update the data code word for 224s (+16s) after a DEXG call had been processed.
