Settings for one 1P 241 with interrupt processing via peripheral byte O (PYO) and no additional
interrupt module.
The DIP switches for interrupt lines S1 .2/S1 .4/S1 .6/S1.8 must be opened.
The interrupt is output as a group interrupt via the peripheral byte O; in this case switch S2.1
must be opened.
Switch
S2.2 must be closed. (After recognition of the address O and of the control signal MEMR,
the acknowledgement signal RDY goes to the CPU of the programmable controller.)
The switches
S2.3 to S2.1 O must be closed.
Thus an evaluation is only possible in OB2 of the programmable controller.
