This input type was created to support a custom application. It is simply a muxed 4-20ma
measurement with defaults of AIO module 1, channel 1, slope-offset processing step, SW-12
warmup of 300ms on DIO module 1, settling time 1000, and filter notch 50. Unless these
defaults happen to match your needs, use the analog 4-20ma input type when 4-20ma
measurement is needed.
PT
This input type was created to support a custom application. It is essentially a muxed 4-wire
bridge measurement with channel selections and other properties fixed based on mux selection.
Unless these defaults happen to match your needs, use the analog bridge input type when
bridge measurement is needed.
Mux
Every measurement input has the capability of being “muxed”, i.e., where the multiple inputs of
the same type connect into a mux device that selects only one of the inputs at a time for
measure. For example, perhaps you have multiple vibrating wire sensors connected to a mux in
a Dam Safety application.
The 8310 supports muxes that are enabled by raising a digital “enable” line, and whose channels
are selected through sequential 1 clock per channel pulses of a digital “clock” line.
By default, the Mux property is set to “None”, meaning the input is not muxed. To enable
muxing of an input, press Right with Mux selected to enter the Mux details menu. Then with the
Mux Name property highlighted, press Set (or Enter), to change the Mux Name property to the
name of the mux you’d like to use. To create a new mux, select “MuxA <new>” to define a new
mux (if other muxes are already defined, the prompt may be for “MuxB <new>”, or “MuxC
<new>”, etc.).
MuxChannel
When the Mux property is set to something other than “None”, the MuxChannel property is
displayed and should be set to the channel to select (i.e., “clock-in”), when it is time to measure
the input.
Mux Details Menu
When the Mux property is set to something other than “None”, you can change the following
mux properties from the details menu:
Name
This is the name of the mux selected for the input, or None. You can create new muxes
from this menu by selecting the “MuxX <new>” option (where X may be A, B, C, etc.).
