Note that all external inputs (from the camera, TTL inputs, and PLC controls) are resynchronized. The

outputs from the look-up table are synchronous.

The LUT is programmed using a simple language. This language allows you to create logical equations

that specify the conditions that set particular outputs

Note: There is a delay of two clock cycles between the inputs of the LUT and its outputs. A clock cycle has

a period of 30 nanoseconds, so the delay is 60 nanoseconds.

The signals in the PLC Control Block are defined in the tables below.

Inputs to CamExpert are labeled In (where n is an integer from 0 to 7) and outputs are labeled Qn (where

n is an integer from 0 to 15).

PLC Input Signal Routing Block

The following code sets the first entry in the PLC’s signal routing block: Setting the Signal Routing Block

is complicated by the fact that each entry in the table has a different set of enumerated inputs. So for

example, a value of 0 for i0(i.e. GPIO Input 0) means something different for i6 (i.e. Pulse Generator 1

Output). Below is a table of enumerated values with respect to each entry.

For more information on the Signal Routing Block, refer to the section below, Signal Routing Block on

page 89.
