Can we give Force Access for SIL 3 Blocks
Can anyone guide me.
Can we give Force Access for SIL 3 Blocks(ex:SDInBool Block) as like SIL 2 Blocks.
I have Given the SIL Access as Confirm from Object type structure and control structure ( for Application, Program, Block,Tag). And Also set the Max no. of Forces more than 0.
System Details: System 800xA 5.1 FP4
We can give confirm access to each object only when if you are using PM865 with SM810(SIL2) or with SM811(SIL3) with application should be SIL marked.
The Access Enable input(I2) on Sm811/Sm810 needs to be active to allow download to the AC 800M HI since write operations to variables configured as “confirm and access enable” are restricted by this input only.
Ensure the following: You should be in offline before performing these activities
1.Define the confirm or confirm access for global/local realio/boolio if any.
2.Define the confirm or confirm access for each objects wherever you required write operation.
3.Set the no of max no of forces/application
4.Download the project again.
