Safety Add-On Instructions Appendix B
Create Signature History Entry
The signature history provides a record for future reference. A signature history
entry consists of the instruction signature, the name of the user, the timestamp
value, and a user-defined description. Up to six history entries may be stored. You
must be offline to create a signature history entry.
Export and Import the Safety Add-On Instruction
When you export a safety Add-On Instruction, choose the option to include all
referenced Add-On Instructions and User-Defined Types in the same export file.
By including referenced Add-On Instructions, you make it easier to preserve the
signatures.
When importing Add-On Instructions, consider these guidelines:
• You cannot import a safety Add-On Instruction into a standard project.
• You cannot import a safety Add-On Instruction into a safety project that
has been safety-locked or one that has a safety task signature.
• You cannot import a safety Add-On Instruction while online.
• If you import an Add-On Instruction with an instruction signature into a
project where referenced Add-On Instructions or User-Defined Types are
not available, you may need to remove the signature.
Verify Safety Add-On Instruction Signatures
After you download the application project containing the imported safety Add-
On Instruction, you must compare the instruction signature value, the date and
timestamp, and the safety instruction signature values with the original values you
recorded prior to exporting the safety Add-On Instruction. If they match, the
safety Add-On Instruction is valid and you can continue with the validation of
your application.
Test the Application Program
This step consists of any combination of Run and Program mode, online or
offline program edits, upload and download, and informal testing that is required
to get an application running properly.
The Signature Listing report in RSLogix 5000 software prints the instruction
signature, the timestamp, and the safety instruction signature. Print the
report by right-clicking Add-On Instruction in the Controller Organizer and
choosing Print>Signature Listing.
