4. Input port mapping
In order to get correct information, TIG 2go requires the input ports DI0 to DI3 be mapped to the fol-
lowing signals from the machine:
4.1.
Status information
The first two wires are expected to be connected to a continuous signal for the machine and produc-
tion status. Each change of TRUE/FALSE in any direction is considered a status change and will be
recorded.
Input Port
Meaning
Explanation
DI0
ONLINE / OF-
FLINE
Signals the “on” state of the connected device, e.g. a machine. A “True”
signal is interpreted as ONLINE, “False” as OFFLINE.
In order to provide useful information, the machine interface should not
just signal its own “power on” status, but communicate whether or not
the machine itself is up and “ready to go”. The informative value of this
status information depends on the ability of the machine’s host com-
puter to determine and transmit a meaningful machine ONLINE / OF-
FLINE condition.
DI1
PRODUCING /
NOT PRO-
DUCING
Signals whether the device is running.
A “True” signal is interpreted as PRODUCING. This status should be
signaled whenever the production status of the machine is “Production”.
A “False” signal is interpreted as NOT PRODUCING.
As with the ON / OFF status, the informative value of the RUNNING /
STOPPED status information depends on the ability of the machine’s
host computer to properly determine and transmit the machine’s current
production status.
