True-Color-Sensor BFS 33M with IO-Link
Only now is the sensor fully ready!
B1: Teach-In procedure (automatic with object in Precise mode)
1. Position product in front of sensor.
2. Observe wait time (see Table W).
3. Enter Index 0x0400 Subindex 0x2: Tolerance Delta E.
4. Select Index 0x0400 Subindex 0x1: Product number (1...255 or 0x01...0xFF).
(The product is then automatically activated.).
Only after this is the teach-in process completed!
5. Repeat procedure if needed for different products. A new product number (1...255)
must be assigned each time.
Optionally the background can be taught as follows:
6. Remove product (sensor detects the background).
7. Observe wait time (see Table W).
8. Enter Index 0x0400 Subindex 0x2: Tolerance Delta E.
9. Enter Index 0x0400 Subindex 0x1: Product number (65535 or 0xFFFF) for
background (the background is automatically activated.)
Only now is the sensor fully ready!
The wait time after positioning the sensor ensures that it has established a stable
working state before the actual measurements from the sensor are accepted. The wait
time is directly linked to the set value of the averaging, i.e. a longer waiting time is
required for a higher value.

Table W: Wait time after positioning the sensor.
Post-setting the tolerance:
To adjust the tolerance after the teach-in process, first use Index 0x0404 to select the
product number and then use Index 0x0405 Subindex 0x5 to select the tolerance.
Index 0x0403 Subindex 0x5 is used for the background.
B2: Manual specification of the target values for products (without object)
in Precise mode
1. Select Index 0x0404: Select product number (1...255).
2. Index 0x0405 Subindex 0x2 to 0x4: Enter CIELab target values for the product.
