TAA131 - Temperature transmitter IFM - Free user manual and instructions

USER MANUAL TAA131 IFM

• 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 ana- log 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).

• Temperature resistance

Maximum operation time depending on the medium temperatureInstallation 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 sup- port 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 G¼ 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).

BUInstallation and set-up / Operation After mounting and wiring check whether the unit operates correctly. Indication at the sensor in the operating mode: Slave profile Representation of measured values by data bits D16 ... D1 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 bits During one transmission cycle the following data is transferred in data triples.

Only 1 measuring channel is used. The bits E3, E2 and E1 are always 0. The analog values measured are transferred via the data bits D1 ... D16 according to slave profile 7.3. Overflow-Bit Valid-Bit

Overflow-Bit: O = 0: measured value is within the value range O = 1: measured value is outside the value range (above max. value for overload or below minimum value for overload) Valid-Bit: V = 0: measured value not valid V = 1: measured value validTechnical data
