Cause : SI P1 Parameter processor 2 parameter error comes when accessing the Safety Integrated parameters for the processor 2 in the non-volatile memory, an error has occurred.

Note: This fault results in a STOP A that can be acknowledged.

- re-commission the safety functions.
- replace the memory card or Control Unit.

For fault value = 129:
- activate the safety commissioning mode (p0010 = 95).
- adapt the PROFIsafe address (p9610).
- start the copy function for SI parameters (p9700 = D0 hex).
- acknowledge data change (p9701 = DC hex).
- exit the safety commissioning mode (p0010 = 0).
- save all parameters (p0971 = 1 or "copy RAM to ROM").
- carry out a POWER ON (power off/on) for the Control Unit.

For fault value = 132:
- check the electrical cabinet design and cable routing for EMC compliance
