Virtual Data Cables
Two types of Virtual Data Cable (VDC) ports are available on the rear panel
of the 6416dio Digital I/O Module. Fourteen VDC Slots are available system‑
wide, regardless of the current network mode (Auto or Manual). Virtual Data
Cables are not affected by the network sample rate, channel activation
settings, or gain settings.
When a Pro64 module requests to activate a Virtual Data Cable, the Control
Master checks the entire network to ensure that the requested VDC is
available. Depending on the type of VDC requested, one or more VDC Slots
must be available before the request can be granted.
When a VDC Slot has a valid input assignment, the Control Master broadcasts
this information to the entire network. Each module in the network will
display the In Use LED for any valid Virtual Data Cable input.
VDC Slot 11 on the 6416dio
is set to receive GPIO In
from the rear-panel jack.
A remote Pro64 device
is set to output the GPIO
data.
See the VDC info elsewhere in this User Guide for help configuring and using
the fourteen available Virtual Data Cables.
GPIO
GPIO (General Purpose Input/Output) can be used to send contact closure
or voltage‑type control signals through the network. Four input and four
output blocks are provided. Each terminal block can be individually wired.
GPIO inputs can be individually configured to be either Isolated or TTL.
