How the Lookup Table Works

The Looku p Table h as 8 inp u ts (I0 - I7) cap able of tw o states each (tru e, false). Thu s, the ou tp u ts have a total
nu m ber of 256 inp u t com bin ations. The resu lt of each com bination can be 1 or 0.

When you  m od ify the equ ations in the Looku p  Table, the controller calcu lates the resu lts of all 256 inp u t
com binations and  stores the resu lt of each ou tp u t as a 256-bit looku p  table (hence the nam e). There are 18
ou tp u ts (Q0 - Q17), so the controller calcu lates 18 d ifferen t looku p  tables.

The controller then p asses the resu lting 18 looku p  tables to the IP Engine. Know ing the valu e of the 8 inp u ts,
the PLC need s only look u p  the valu e of the resu lting ou tp u t (for each ou tp u t), rather than calcu late it. Thu s,
the Looku p  Table can achieve a p rop agation d elay of only one sys tem  clock cycle (30 ns), regard less of the
com p lexity or nu m ber of Boolean exp ressions.
