also represented in SMT with a cross mark. Hardware channels are always visible
in SMT.
Supported hardware channels are:
• Binary input channels
• Binary output channels
A hardware input channel can be used as often as it is needed. A hardware binary
output channel is taken from the list of available channels when a new channel is
requested. That prevents for using a hardware binary output channel twice. As an
example, see

6.1.9 Validation
GUID-7407C36C-15EB-4987-AF29-5DCEFB95A613 v4
Validation checks the application configuration on errors about the rules and
restrictions defined for doing a MainApplication on three levels.
• During creating the logic while doing a connection or placing a function block.
• On demand by starting the validation.
• When writing the application configuration into the IED.
Validation when creating the application configuration
Validation is made when creating the application configuration, for example:
