Fig. 3.8
When you select a SSEQ instruction in the program and double click it, it will
display as above figure. At this time you can select the output points. If you select
Output 3, output 2 will be selected automatically, the same way for output 4, output
5…output 8. It means that if you select the behind one, then the previous one will be
selected automatically.
As shown in Fig. 3.8, every time when TRG has a pulse, it will make one
output become 1. And when all the selected outputs are ON. The next TRG pulse will
make all the selected output be OFF one by one in turn. But Output 0 will retain the
