Operating behavior

6.1

Internally the TM 225/A measures the temperature value every 1 ms. The slid-

ing mean value from the last 100 measurements (100 ms) is calculated every

2 ms. This value is available at the hardware end point system.TI0 for the

application.

6.2

6.2.1

In case of a module error an internal watchdog monitor will be triggered. The

module signals the module error to the CPU module or bus link module.

6.2.2

The module identifies both a failure in the measurement line, as well as in the

reference currency line. The sensor failure is passed on to the CPU. Once the

sensor failure has been corrected the status "Sensor failure" will be automat-

ically reset.
