Hi All,
I have a S7-400 H redundant system & have included following OBs mentioned in the manual that are required for redundancy -
OB 70,72,80,82,85,86,87,88,121,122.
Do I have to write any more program to activate these OBs or by just including them they start working?
Manual mentions that the OBs are necessary as they prevent CPU from going into stop mode on error. If this correct?
I would like to build a small diagnostic to know what error is causing the SF LED to be lit.
Any suggestions?
Thanks,
