Machine Logic
The surface’s start/stop logic options can be selected via the E-6 GUI. Press
the Options
tab and choose Misc Options from the AVAILABLE OPTIONS scroll
down list to display MACHINE LOGIC choices.
The purpose of this option
is to allow the privileged opera-
tor to determine the conditions
under which START and STOP
signals (referred to herein col-
lectively as DIO signals) are
sent in response to a command
to turn a channel ON or OFF.
Channel ON and OFF com-
mands can come from three
different sources:
• Surface - a channel can
be turned ON or OFF by
a surface action, such as
pressing the ON or OFF
switch, or moving a fader
if EFS has been enabled
• Remote (RMT) - a channel
can be turned ON or OFF
by sending it a command
from a system Logic I/O
card via the RemOn and
RemOff functions, configu
-
rable from within XPoint or
Navigator
• Automation Control In
-
terface (ACI) - various automation systems are capable of sending ACI signals
to the system via Ethernet to turn channels ON and OFF (and perform other
functions as well).
There are four possible start/stop options:
DIO Always—START and STOP (DIO) signals are always sent in response to
channel ON and OFF commands, regardless of the source.
No DIO w/ACI—DIO signals are blocked if the channel ON and OFF com-
mands are from an automation system (ACI).
No DIO w/RMT—DIO signals are blocked if the channel ON and OFF com-
mands are initiated from a system Logic I/O card.
No DIO w/ACI or RMT—DIO signals are blocked if the source of channel
ON and OFF commands is either automation or Logic I/O.
Note that DIO signals are always issued if the corresponding channel ON or
OFF command is initiated by a surface control.
