Safety Partner Fault

The 1756-L8SP safety partner has an OK status indicator.
If the SIL configuration is set to SIL 2 and a safety partner is installed in the slot next the safety primary, these actions occur:
  • On the 1756-L8SP safety partner, the OK status indicator flashes red.
  • The controller logs a Type 14, Code 12 minor fault that indicates that the controller is configured for SIL 2, and a safety partner is present.
  • The programming application refuses to download a SIL 2 application.
