connection you want to use. With the type and connection defined, the software will display
some details of the connections in /diagnostics/inputs.
AIOx:y
x is the analog module number (1 if
there are no external modules
attached) and y is the input channel.
DIOx:y
x is the digital module number (1 if
there are no external modules
attached) and y is the input
channel.
SDI xy
x is the SDI address and y is the
command
Note that some inputs such as a differential analog signal or quadrature, require connection to
two adjacent channels.
Grounds
The 8310 has three different grounds on the protection/termination board: analog, digital and
chassis.
The analog grounds are labeled with AGND (B1, B5, B9, B12, B15). The analog grounds are tied
together on the protection/termination board and then the signal takes a separate path to the
A/D converter where it is tied to digital ground.
The digital grounds are labeled GND and are wired internally all together from the A, C and D
terminal strips.
The Chassis Ground is a lug or wire that comes off the protection/termination board. All the
surge protection devices connect to the Chassis Ground. The internal metal plates are also
connected to the Chassis Ground. There is a maximum of 100 ohms between the Chassis Ground
and digital ground.
Sensor Setup Examples
The following examples show the details of the 8310 setup for some common sensors.
