The SF is a segment fault on profibus, and the PF is a power fault however these can be misleading, or at least not descriptive.
A normal action to ensure that its not a controller fault is to perform a PLC and NCK reset, however this will wipe whatever PLC program and NCK configuration is in there. If you are not the OEM of the machine, you may be in a world of trouble if you attempt this without a working and current backup and the ability to restore it with a PG/PC and MPI cable.
You mentioned that you relocated the machine. If anything was disassembled, then I would ensure that your power connections are measured and correct, and that your profibus connections are all correct. If you did not place the same profibus cables back on the same terminals, this may result in a problem. In certain topologies, a terminating resistor is required at the end of a bus line or the end of a branch. If these were moved (terminations are not on the same places that they originally were) this can cause this problem.
Also, check all your estops and wiring of any off board estops you may have. Often these are implemented where an e-stop will put the siemens control into this state.
