Check SIL 2 Reset Status

If one of more errors have persisted longer than the Connection Reaction Time

Limit (CRTL), the connection uses safe state values and requires a reset to

recover. When online, the SIL 2 reset status is displayed on the SIL 2 Safety tab

for output modules.

Click Reset to reset the connection and enable the output modules to control

their outputs based on logic. To reset the connection for input modules, create a

reset tag within the Add-On Instruction. See

Chapter 7

for details.

View Module Information

The configuration signature displayed on the SIL 2 Safety tab is composed of an

ID number, date and time. The signature is updated whenever the module

configuration is changed. You can use this signature to enforce the use of a

specific configuration within your application. The signature is found in the

CRC member of the module’s SIL 2 configuration tag. This is the only occasion

where this tag should be accessed directly.

If you want to keep a record of the signature, you can click Copy to copy the

signature to the Windows clipboard.
