Characteristics of Safety Tags, the Safety Task, and Safety Programs<br />
For Cat 1, Cat 2, and SIL 2 safety functions, the Guard I/O safety<br />
modules need specific configurations within the <strong>GuardLogix</strong> project.<br />
In this example, inputs 0, 1, 6, 7, 8, 9, 10, and 11 are part of a CAT 1,<br />
2 or SIL 2 safety function. Inputs 2 and 3, as well as 4 and 5 are part of<br />
a CAT 3, CAT 4, or SIL 3 safety function.<br />

Safety Pulse Test<br />
Set values based on how the field device is physically wired to the<br />
module. To make sure the test source is properly enabled, open and<br />
view settings on the Test Output tab.<br />
User input based on field device characteristics.<br />
IMPORTANT<br />
The onboard pulse test outputs (T0…Tx) are typically used with<br />
field devices that have mechanical contacts. If a safety device<br />
that has electronic outputs is used (feeding safety inputs), they<br />
must have the appropriate safety ratings.<br />
IMPORTANT<br />
If you are using <strong>GuardLogix</strong> Safety Application Instructions, be<br />
sure to configure your safety input modules as single, not<br />
equivalent or <strong>com</strong>plementary. These instructions provide all<br />
dual-channel functionality necessary for PLd (Cat. 3) or<br />
PLe (Cat. 4) safety functions.<br />
