ValveLinkt Software
Note
The Link Active Scheduler (LAS) controls traffic on the
H1 segment. For an active H1 segment, the LAS
function is provided by the host system or another
FOUNDATION fieldbus device. When ValveLink Solo is
connected (to either an active segment or a single
instrument), the NI-FBUS interface card waits to see if
the LAS is present. If not, the NI-FBUS interface card
provides the LAS function. Therefore, to avoid conflict
between the LAS function in the NI-FBUS interface
card and LAS on the active segment, do not disconnect
ValveLink Solo from a single instrument and connect it
to an active segment without first shutting down
ValveLink Solo.
To avoid personal injury or property damage due to
loss of process control, do not connect the
computer to an active H1 segment while ValveLink
Solo or NI-FBUS software is running. Doing so
could interfere with Link Active Scheduler (LAS)
operation.
