Logic Function Blocks

The Honeywell Spyder provides the following Logic function blocks that you can configure and use to build your application logic:

Inputs to Logic Function Block may come from either Digital or Floating point variables.

For digital inputs

For floating point variables

An output sent to a Digital variable is either 0 or 1. Similarly, an output sent to a float point variable is either 0.0 or 1.0.

Note: Logic blocks outfitted with trueDelay and falseDelay allow fast changes on the inputs to be ignored. On power up/ preset the output read of any logical block gets a value of 255 by default, so when the block computes a new desired output of FALSE and the old output is TRUE(255), it turns on the output (TRUE) and delays changing the output to FALSE for the false Delay. So the user first sees an ouput as true and after the false delay seconds sees the actual output(false).
