The characteristics of the thermocouples can be found in DIN 43710 or IEC 584. The
characteristic curve of the Pt 100 can be found in DIN 43760. The characteristics of the
permitted sensors are linearized internally by the firmware. The selection of sensors is made in
the parameter assignment (see Part 3 of this manual).

3.4.3 Setting the Clock
To allow maximum interference suppression at main frequencies of 50 Hz or 60 Hz, the
integration time can be selected.

3.4.4 BASP Evaluation
It is possible to evaluate the BASP signal or to disable the evaluation using jumper X8/4–X9/4.
When BASP = 1, the outputs are disabled.
If there is no BASP evaluation, you must use external measures to make certain that
the machine will be forced into a safe operating state in case of error (see also
IEC 204-1). If the S5-CPU is in STOP, it can no longer react to error messages from the
IP (e.g. actual value too large, watchdog, ...).
