Functionality

When the Test mode functionality TESTMODE function is activated, protection
functions in the IED are automatically blocked. It is then possible to unblock the
protection functions individually from the local HMI or the Parameter Setting tool
to perform required tests.
When leaving TESTMODE, all blockings are removed and the IED resumes
normal operation. However, if during TESTMODE operation, power is removed
and later restored, the IED will remain in TESTMODE with the same protection
functions blocked or unblocked as before the power was removed. All testing will
be done with actually set and configured values within the IED. No settings will be
changed, thus mistakes are avoided.
Forcing of binary output signals is only possible when the IED is in test mode.
