No. Description

1

The measured temperature value is digitized.

2

The temperature signal is adjusted digitally per default.

3

The sensor monitoring continuously checks the correct function of the sensor signal and triggers high-priority emergency

frames in the event of an error.

4

The measured temperature value can be scaled to any measuring units (or in % of the measuring range).

5

The fine adjustment features a freely adjustable characteristic line offset.

6

Undesired signal fluctuations can be suppressed using the adjustable filter constant.

7

The measurement output has a freely selectable decimal place.

8

Free choice of upper and lower limits for range monitoring. The result is given as a status byte in addition to the measurement

in the PDO frame.

9

The drag pointer (“min./max. index”) function records the minimum and maximum temperature values.

10 The date and name of the last maintenance operation can be saved.

11 The emergency frame is triggered in the event of a sensor fault.

12 The PDO frame contains a 32-bit measurement and a 8-bit status. The measurement output can be controlled by means of

different trigger conditions.

13 SDO frames can be used to set parameters and to request measured values and statuses.

14 The heartbeat signal can be used to additionally monitor the function of the transmitter.

15 The sync command can also be used to control the transfer of the measured values.

16 The NMT frames are for the purpose of controlling the operating status of the transmitter.

17 The CAN Node ID and the CAN baud rate are set either with LSS or SDO.
