Afte r the bottle is filled, the control program will wait 0.7 seconds before moving to the next bottle. The program will includestart and stopcircuits for the outfeed motorand the start of the process. Table 1 shows the I/O address assign ment, whil e Table s 2 and 3 presen t the internal and register assignments , respectively. These assignments inclu de the start and stop process signa ls.
