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 PROFIBUS PA is compliant with the PNO Profile for
Process Control Devices version 3.02 – Class B [Ref. 2].
The AWT210 PROFIBUS PA is a compact slave device
implementing:
• one Physical Block (PB)
– the PBs 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 instructions) 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 AWT210 PA is a Bus Powered device with Profibus PA
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 PROFIBUS®.
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.
