3.5 Outputs

All models have two analog outputs and two discrete outputs (discrete output 1 is an IO-Link output).
The analog outputs are 0–10 V. They may be configured (via DIP switch or IO-Link interface) for either a positive or negative
slope.
Discrete output 1 is always used for measurement; discrete output 2 may be used either for alarm or measurement operation
(selectable via DIP switch or IO-Link interface). When the receiver interface is used, discrete output 1 and analog output 1
follow the same measurement mode. When the IO-Link interface is used for configuration, discrete output 2 has full
configurability, including measurement mode, NPN or PNP polarity, and normally open or normally closed operation. Discrete
output 1 has the same configurability as discrete output 2, except for NPN or PNP polarity. Discrete output 1 is a dedicated
push-pull output.

3.5.1 Analog Output Configuration

Analog output configuration assigns analog outputs 1 and 2 to one of the measurement modes described in
Mode Selection. When the selected measurement mode involves first or last beam blocked or made (unblocked), the
assigned output will vary in proportion to the beam number identified during a scan. When the measurement mode involves
total beams blocked or made, that assigned output will vary in proportion to the total beams counted during a scan.
Analog outputs may have a filter setting (to smooth the output) and Zero Value (to specify the output value when the
measurement mode value is zero) set in the IO-Link v1.1 interface. For more information, refer to the IO-Link Data Reference
Guide (p/n 220588).

3.5.2 Discrete Output Configuration

Discrete Output 1; Receiver Interface
When the receiver interface is used for configuration, the measurement mode assigned to discrete output 1 is the
same as that assigned to analog output 1. When the analog output detects a target present, discrete output 1
conducts (normally open).
Discrete Output 2; Receiver Interface
Discrete output 2 (only) has two options: alarm and complementary (measurement) operation.
Alarm—Output 2 energizes when the receiver detects a sensor error (such as a disconnected cable) or
whenever the excess gain of one or more beams becomes marginal.
Complementary (Measurement)—Discrete output 2 operation is complementary to discrete output 1 (when
output 1 is ON, output 2 is OFF, and vice versa).
Discrete Output 1 and 2 Configuration; IO-Link v1.1 Interface
When the IO-Link v1.1 interface is used for configuration, the discrete outputs have more options: either discrete
output can be assigned to any of the measurement modes, high and low set points can be added, the outputs can
be inverted, and hysteresis values can be set, as well as a scan number to smooth output performance. Discrete
output 2 can be assigned to alarm mode via the IO-Link v1.1 interface also.

3.6 Scanning Method

One of three scanning methods may be configured:
• Straight Scan
• Single-edge Scan
• Double-edge Scan (1, 2, 4, 8, 16, or 32 steps)
Sensor response time is a function of sensor length and scanning method. Maximum scan times are shown in
Scan Times in SIO Mode on p. 15.
