Sensor type
Specifies which sensor type is connected (see Table 3-1 Pin assignment for
DI 8×NAMUR HF (Page 9)).
For the following sensor types
● NAMUR changeover contact
● Changeover contact, unconnected
● Changeover contact with 10 kΩ
the following applies: The normally open contact channel must be set according to the
sensor type. The normally closed contact channel must be deactivated.
If "Channel deactivated" is shown, this means that the channel is not activated.
Pulse stretching
Sets whether and for how long pulse stretching is to take place.
Pulse stretching is a function for changing a digital input signal. A pulse at a digital input is
extended to at least the configured length. If the input pulse is already longer than the
configured length, then the pulse will not be changed.
Inverted
Specifies whether or not the input signal is to be inverted.
Inversion is only possible with the following sensor types:
● NAMUR sensor
● Single contact, unconnected
● Single contact with 10 kΩ
Potential group
Specifies that a BaseUnit with an incoming supply voltage is located in this slot (see
ET 200SP distributed I/O system
(http://support.automation.siemens.com/WW/view/en/58649293) system manual).
