4.5 Digital Output Selector

Chap. 4 BLOCK DIAGRAMS FOR CONTROL LOGIC
The block diagram shown in Figure 4.4 shows you the processes to select the internal logic signals for feeding to
two digital output signals [Y1] and [30A/B/C]. The output terminals [Y1] (a transistor switch) and [30A/B/C]
(mechanical relay contacts) are programmable. You can assign various functions to these terminals using
function codes E20 and E27. Setting data of 1000s allows you to use these terminals for the negative logic
system.
