One of the conditions to be met is that communication error, if they occur, do not jeopardize the protective and control functions. The question is how to evaluate this if a componenent (e.g. switch/router/hub) is tested seperately of the system? On page 15 (clause 4.2.3) of the standard it is also mentioned that protection functions shall operate autonomously. This seems to be in contradiction with the conditions to be met.
