Blocks.

4.9 Designing the Control Logic
To design the control logic:
1. Add the desired Safety and Non-Safety Inputs:
•
On the Equipment view: click
under the module to which the input will be connected (the module can
be changed in the input Properties window)
•
On the Functional View: click any of the empty placeholders in the left column
See
Adding Inputs and Status Outputs
on page 19 for more information and device properties.
2. Add Logic and/or Function Blocks (see
on page 26) by clicking any
of the empty placeholders in the middle area.
NOTE: The response time of the Safety Outputs can increase if a large number of blocks are
added to the configuration. Use the function and logic blocks efficiently to achieve the optimum
response time.
3. Create the appropriate connections between added inputs, Function and Logic Blocks, and Safety Outputs.
NOTE: The Check List on the left displays connections that are required for a valid
configuration and all items must be completed. The controller will not accept an invalid
configuration.
Tip: To aid with creating a valid configuration, the program displays helpful tooltips if you
attempt to make an invalid connection.
