Acceptance of Changes to the Safety Program

To accept changes to the Safety Program, proceed as follows:
1. Save the program
2. Compare the new program with the accepted one (see the section entitled
"Comparing Safety Programs").
3. Check the changes in the printout
4. Download the new program to the CPU
5. Carry out a functional test of the changes
When you check the printout and carry out the functional test, only the new
sections and sections with changes have to be checked.
To identify these, the new program is compared with the accepted program.
The accepted program must be saved in another project. Click "Browse", and enter
the path of the accepted program.
Changes to the safety-relevant configuration of F-I/Os can be recognized by the
change to the CRC_IMP1 and CRC_IMP2 parameters of the relevant F module
driver (F_M_xx).
