Releasing the function to be tested

Release or unblock the function to be tested. This is done to ensure that only the function or the
chain of functions to be tested are in operation and that other functions are prevented from operating.
Release the tested function(s) by setting the corresponding Blocked parameter under Function test
modes to No in the PCM600.
When testing a function in this blocking feature, remember that not only the actual function must be
activated, but the whole sequence of interconnected functions (from measuring inputs to binary
output contacts), including logic must be activated. Before starting a new test mode session, scroll
through every function to ensure that only the function to be tested (and the interconnected ones)
have the parameters Blocked and eventually EvDisable set to No and Yes respectively. Remember
that a function is also blocked if the BLOCK input signal on the corresponding function block is
active, which depends on the configuration. Ensure that the logical status of the BLOCK input signal
is equal to 0 for the function to be tested. Event function blocks can also be individually blocked to
ensure that no events are reported to a remote station during the test. This is done by setting the
parameter EvDisable to Yes.
Procedure

In order to get the following information in SAM600-IO, the LHMI service kit is need. For
more information on LHMI service kit, refer section User interface.
Any function is blocked if the corresponding setting in the local HMI under Main menu /
Test /Function test modes menu remains On, that is, the parameter Blocked is set to
Yes and the parameter TESTMODE under Main menu/Test /IED test mode remains
active. All functions that were blocked or released in a previous test mode session, that
is, the parameter Test mode is set to On, are reset when a new test mode session is
started.
