4. Signals and symbols
A symbol is an item with a certain logical function, it can
manipulate a “signal” in many different ways: pulse, stretch, delay,
keep high, keep low, set value, change value, …
Symbols (hardware and software) are interconnected with “signals”:
-Digital: High/Low – 1 or 0 =
Blue
- Analog: Value between 0 and 100% (corresponds with analog
channel) =
Red
-Serial: Data (text,…) Black
Functions “without” brackets have to
be used, otherwise you will get an
error message *!* Incomplete
Symbol (required in or output is
missing) and the symbol will
malfunction or NOT at all.
Functions “with” [brackets] do
not have to be used, they are
optional and can be used when
required
“Parameters have to be filled in,
otherwise you will get an error
message *!* Incomplete Symbol
(required in or output is missing),
and the symbol will NOT function
Pressing “F1”on a
selected symbol will give
you a complete detailed
description. (see also SW
manual on the Control CD)
