The logic states of up to 16 operands (M. I, 0, T, C) can be displayed graphically on the screen at the same<br />
time. 1024 PLC scans can be traced.<br />
A table is displayed from which the desired operands can be selected. The control requests the positions of<br />
the table in a dialog. Wrong inputs can be cleared by pressing DEL. It is possible to enter a trigger condition<br />
for each operand. 512 states are traced before and after a trigger event. The following trigger conditions are<br />
possible:<br />
II II<br />
1 +<br />
trace if the operand is a logical “1”<br />
(trigger on positive edge)<br />
trace if the operand is a logical “0”<br />
(trigger on negative edge)<br />
no trigger<br />
If no trigger condition is entered for any of the operands,<br />
the operand states are traced continuously and the last<br />
1024 states are stored.<br />
e.g. 0 I5 1 + trigger on positive edge<br />
1 06 2 + trigger on negative edge<br />
2 M7 --f no trigger<br />
