Clock Selection; Basp Interpretation - Siemens SIMATIC S5 Manual

The following table specifies the maximum actual values that can be read:
Please refer to DIN 43710 or IEC 584 for the characteristic curves of the thermocouples. The Pt
100 curve has been taken from DIN 43760. The characteristic curves of the valid sensors are
linearized internally by the firmware. The sensors are selected by configuration (see Section 3
of this Manual).

3.4.3 Clock Selection

The integration time can be selected to obtain maximum noise suppression at 50 Hz or 60 Hz
mains frequency.

3.4.4 BASP Interpretation

The BASP signal can either be interpreted or interpretation can be disabled by the X12/1–2
jumper. BASP = 1 resets the output registers.
X12/1–2 open:
X12/1–2 inserted:
If BASP is not interpreted, additional external measures or devices must ensure that the
machine is forced to a safe operating state in the event of a malfunction (cf IEC 204–1).
In STOP mode, the S5 CPU is unable to respond to error messages from the IP (e.g.
actual value too high; watchdog, ...).
