5.2.
Formal event syntax
The grammar for defining events is very C-like. The following identifiers are
recognized:
Analogue variables can only be compared to constant values (mV for
voltages, mA for currents). Every analogue variable can be compared
against at most two constants, due to the availability of only two
comparators in firmware.
A formal definition of the grammar is given below.
PRIMARY_BOOLEAN ::= 'true' | 'false' | ('(' EXPR ')')
PRIMARY_ANALOG ::= ['0'-'9']+ | 'U_tg' | 'I_tgpwr'
RELATIONAL_ANALOG ::=
U_tg
I_tgpwr
true
false
