These momentary pushbutton objects write the two integers to the
GuardPLC controller. Tags N123:0 and N123:1 were used to match the
output assembly used in the GuardPLC controller. The GuardPLC
controller does not use the ‘N’; it is required for FactoryTalk View
software.
N123:0 corresponds to the first two BOOL tags in the GuardPLC
assembly 123. The first tag changes between 0 and 1; the second is
the dummy tag. N123:1 corresponds to the next two BOOL tags in the
GuardPLC assembly 123.
