FSO module version handling

To ensure backward and forward compatibility with the ACS880 drives, the FSO-21
module has a version handling system. Both the FSO module and the ACS880 drive
firmware must support the used safety functions.
You can always replace the FSO-21 module with a newer revision and use the same
configuration file with the new revision. If you replace an FSO-12 module with an
FSO-21 module, you have to re-configure the FSO module and safety functions.
Each time you make any changes in the safety system, you must do the acceptance
test to each safety function using the checklists described in chapter Verification and
validation.
Each new revision of the FSO-21 module supports all functions of previous FSO-21
module revisions and it can be used together with previous ACS880 drive firmware
versions. In addition, previous FSO-21 module revisions can be used together with
new ACS880 drive firmware versions. In this case, the drive supports only the
functions of the previous FSO-21 module revision.
Each safety function and parameter group has a separate version parameter. With
these parameters, the user selects the desired versions according to the drive
firmware and FSO-21 module combination at the start-up. Only the versions that both
the used ACS880 drive firmware and the FSO-21 module support are shown in the
Drive composer pro PC tool.
