Chapter 7 1715 Redundant I/O System in SIL 2 Safety Applications
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 8
for details.
View Module Information The configuration signature that is 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 SIL 2 configuration tag of the
module. This is the only occasion where you access this tag directly.
If you want to keep a record of the signature, you can click Copy to copy the
signature to the Windows clipboard.
