Counter information
With the last two wires TIG 2go maintains two counters for produced parts
—one for good parts
(“yield”) and one for bad parts (“scrap”). In order to provide these counters with meaningful infor-
mation, the machine has to signal after each cycle
that a cycle was completed, and
whether the cycle was good or bad.
There are two different ways for machines to signal good and bad production cycles. TIG 2go will han-
dle the different behavior of the machine interface on the platform according to the machine specific
configuration provided during registration.
4.2.1. Alternate signaling systems
After every completion of a good cycle this information is signaled over one wire (the “good” signal
line), whereas a bad cycle is signaled over the other wire (the “bad” signal line). Good and bad cycles
will therefore result in raising a “True” signal in one of the two counter lines (but never in both of them
at the same time).

Explanation
DI2
GOOD CY-
CLE
Signals the completion of a “good” cycle that resulted in the production of
a good part or several good parts, depending on the mold’s cavity. The
part or parts produced are counted as good.
On each “True” signal received, the GOOD PARTS COUNTER is incre-
mented.
DI3
BAD CYCLE
Signals the completion of a “bad” cycle that resulted in the production of
scrap.
On each “True” signal received, the BAD PARTS COUNTER is incre-
mented.
