Frequently Asked Questions - TAA131 IFM

What is the measurable temperature range of the TAA131?

The measuring range is -10 °C to 150 °C (or 14 °F to 302 °F).

How to address the TAA131 slave on the AS-i network?

The address is adjustable from 1 to 31 via an addressing unit, the AS-i master, or AS-i software on PC (AS-i 2.11). At delivery, the address is 0.

What does the flashing red LED on the TAA131 mean?

A flashing red LED indicates an internal error. The error is reported to the master as a peripheral fault.

How to connect the TAA131 to the AS-i network?

Connect the sensor via the M12 connector: the brown wire (1) to ASI+ and the blue wire (3) to ASI-. Power is supplied by the network.

What are the materials in contact with the fluid?

The wetted parts are made of stainless steel 316L.

What is the accuracy of the temperature transmitter?

The accuracy is ± 0.1 K at 60 °C and ± 0.3 K over the full range of -10 to 150 °C.

Can the TAA131 measure negative temperatures?

Yes, the measuring range goes down to -10 °C.

How to interpret the transmitted analog values?

The values are 16-bit signed two's complement, according to slave profile 7.3. The resolution is 0.1 °C.

What is the required supply voltage?

Power is supplied by the AS-i network, typically 26.5 to 31.6 V. Consumption is less than 25 mA.

Where to find the dimension drawing of the TAA131?

Dimensions are provided in the dimension drawing (Maßzeichnung) on page 19 of the manual.

Functions and features

The temperature transmitter operates as a single slave in the AS-i network (slave profile S-7.3.C).

• It detects the current system temperature,
• converts it into digital coded analog values
• and transfers these values to the control level (master, controller or host).

Analog value representation

Signed 16-bit value as two's complement value. The analog value transmission protocol is specified in the slave profile 7.3.

A master of AS-i version 2.11 detects the slave automatically. The analog value transmission to slave profile 7.3 is then supported. Masters of AS-i version 2.0 require a special driver (additional function block, available as an accessory).

• Measuring range: -10 ... 150°C / 14 ... 302°F
• Measuring element: Pt 1000 to DIN EN 60751, class A
  • Temperature resistance

Maximum operation time depending on the medium temperature

Installation

Addressing

You can address the sensor by using an addressing unit, the master or by means of the AS-i software of the host (the components must support AS-i version 2.11).

Assign an address between 1 and 31. At the factory the address is set to 0.

Mechanical installation

Mount the unit to G ^1/4 process connection.

Connection to the AS-i system

Connect the sensor with the AS-i system by using the M12 connector. Voltage is supplied via the AS-i network. Wiring:

Referring to UL: For use on a low voltage circuit with overcurrent protection in accordance with UL873 Tab. 28.1 or Imax = 100/Ub (Ub = voltage of the circuit).

Installation and set-up / Operation

After mounting and wiring check whether the unit operates correctly. Indication at the sensor in the operating mode:

LED green ON = unit is then ready for operation
LED red	ON = no communication
	FLASHING = internal faultis transferred to the master as periphery fault

Fault handling

Automatic fault handling according to AS-i version 2.1.

• Power-up: During power-up the data is marked faulty until a valid data transfer is guaranteed.
  • After interruption of the data communication the watchdog function starts communication again.

- Data triple in wrong order: If a fault occurs, the sensor sets its data triples to 0 (invalid) and waits for a new triple sequence.

Data bits

During one transmission cycle the following data is transferred in data triples.
