1.2 PLC operation (option)<br />
Loading a mask via PLC<br />
Conversion of<br />
binary numbers<br />
Process<br />
With this option one mask out of up to 127 masks (files with ending *.msk) can<br />
be selected and loaded via a PLC (programmable logic control).<br />
The number of the mask is transferred binary coded. The order of the masks is<br />
determined in System > Options on the tab "File selection" (see chapter 4).<br />
Binary numbers can be simply converted into decimal numbers. The value of a<br />
binary number results from summating its digits that are previously multiplied<br />
with its place value 2 i :<br />
Example: [101]2 = 1*2 2 + 0*2 1 + 1*2 0 = [5]10<br />
[1111110]2 = 1*2 6 + 1*2 5 + 1*2 4 + 1*2 3 + 1*2 2 + 1*2 1 + 0*2 0 = [126]10<br />
The number of the mask to be loaded must be pending stably at the inputs E2.0<br />
to E2.6 at least 100 ms before data transfer:<br />
Mask to<br />
load<br />
E2.6 E2.5 E2.4 E2.3 E2.2 E2.1 E2.0<br />
1 0 0 0 0 0 0 1<br />
2 0 0 0 0 0 1 0<br />
3 0 0 0 0 0 1 1<br />
4 0 0 0 0 1 0 0<br />
5 0 0 0 0 1 0 1<br />
...<br />
127 1 1 1 1 1 1 1<br />
Tab. 15<br />
If the data are pending stably the input E2.7 (data transfer) operates. For<br />
validation the control sets the output A2.0 (data transferred) until the selected<br />
mask is available for marking, but for at least 200 ms. If less masks are saved<br />
than the transferred number demands, the control sets the output A2.1 (error<br />
data transfer). This error is pending with A2.0 (data transferred), until it is<br />
acknowledged by pressing of any button at the control or by setting of the input<br />
E1.6 (acknowledge error).<br />
Note<br />
With the optional digit encoding switch number >127 are interpreted as 127. As<br />
hundreds you can only select 0 and 1.<br />
