* - value 1 shifts between Q1 and Q2 depending on their state in last working cycle
(if Q1=1 and Q2=0 then in next cycle it will shift to Q1=0 and Q2=1
The first program line resets REG1 to 0 (executed only on first scanning of program- later
on omitted since the condition is not met). Operations on REG1 and M0 flag prepare tasks
for the next sequence of pumping using Q1 and Q2. Altering functionality is based on
checking the value of the first bit in REG1. The bit changes its value for each change of M0
marker).
9.14.5. 3 pumps toggle action
In this example, the levels of starting and stopping of 3 binary outputs are designed exactly
as the previous example for two pumps (I1,I2,I3,I4). The pumps alternate between Q1 Q2
