4 Device overview

Four variants of AWT210 are available for use with pH, ORP,
pION, and conductivity sensors.
Supported sensors:
• pH
• 2-electrode conductivity
• 4-electrode conductivity
• toroidal conductivity
The AWT210 FOUNDATION Fieldbus is compliant to the
communication Protocol FOUNDATION Fieldbus specification
ITK6.3.1.
The AWT210 FOUNDATION Fieldbus version is a compact slave
device implementing:
• one Resource Block (RB)
– the RB describes the necessary parameters and functions
of the device or the operation of the device hardware
itself.
• four Transducer Blocks (TB)
– the TBs contain the parameters of a device representing
the necessary parameters and functions of the
connection to the process.
– Examples are measured process values, the type of
sensor and the calibration data.
– There is one transducer block for each sensor type.
• two Function Blocks (FB)
– both function blocks are AI blocks.
– each FB can be connected to one TB at one time.

Process interface

Sensor Input Channels

The sensor module provides 8 terminals marked 1 to 8, 1 to 4
for Process Variable (detailed in Commissioning Instruction
[CI/AWT210-EN]) and 5 to 8 for temperature sensor (up to 3
wire RTD + shield).
Operating ranges correspond to the capabilities of each sensor
type.

Host interface

The AWT210FF is a bus powered device with FOUNDATION
Fieldbus communication. The communication module provides
5 terminals for bus power & functional earth connection.
• Terminals 1(A) & 2(B) are for polarity independent bus lines.
• Terminal 3 ( ) provides a functional earth connection
• Terminals 4(A) & 5(B) are a repeat of Terminals 1(A) & 2(B)

Local interfaces, jumpers and switches

Local controls and displays

• The Device has a 75 x 65 mm (3.00 x 2.55 in.) monochromatic
dot matrix LCD display and 4 push buttons

Internal jumpers and switches

The device has 2 internal switches, situated on the top
righthand side of the communication module –
see Figure 2, page 8:
• SW1: Reset to Defaults
– if the device is powered up with SW1 in the ON position it
returns device setup to default factory settings.
– if powered up with SW1 in the OFF position the device
retains previously saved user settings*.
• SW2: Write Protection
– If SW2 is in the ON position HW write protect shows as
enabled and the user is unable to make changes to setup
or send Write commands via FOUNDATION Fieldbus.
With SW2 in OFF position the user is able to make
changes/send commands providing they are in a
sufficient access level and Software Write Protect has
not been enabled.
*Note: Reset to defaults is not performed if SW2 Write
Protection is ON.
