6.4 Limitations<br />

- Pulses or delays are not transmitted over cross connections.<br />

- Logical conditions can be defined using NOT, AND and OR (Option:<br />

Advanced functions).<br />

Examples:<br />

- di2=di1<br />

- di3=di2<br />

- do4=di2<br />

If di1 changes, di2, di3 and do4 will be changed to the corresponding value.<br />

- do8=do7<br />

- do8=di5<br />

If do7 is set to 1, do8 will also be set to 1. If di5 is then set to 0, do8 will also be<br />

changed (in spite of the fact that do7 is still 1).<br />

- do5=di6 and do1<br />

Do5 is set to 1 if both di6 and do1 is set to 1.<br />

A maximum of 10 signals can be pulsed at the same time and a maximum of 20<br />

signals can be delayed at the same time.<br />
