Test mode functionality TESTMODE

Functionality

When entering IED test mode there is an option to block all functions. Active test
mode is indicated by a flashing yellow Start LED on the LHMI. After that, it is
possible to unblock arbitrarily selected functions from the LHMI to perform
required tests.
When leaving TESTMODE, all blockings are removed (except for functions that
have their block input active), 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 input and output signals is only possible when the IED is in IED
test mode.
