Modular Pick by Light system configuration

Sensors

Sensors for quality control in real time

The pick-by-light sensors use a reflective measurement process to determine whether an item has been removed. This information is passed on to the pick-by-light software, which then authorises the next work step. This ensures that the work process can only continue if all items have been correctly removed. This enables efficient quality control in real time.

The RS485 ModBUS sensors are controlled by the SETAGO® software. In the so-called Time-of-Flight (ToF) process, an emitter emits infrared light with a wavelength of 940 nm. The integrated collector in the sensor measures the distance to the reference plane (zero point) based on the time required by the reflected infrared light. This method assumes that each sensor always has a reference plane.

The power supply and communication between the sensor and the control unit takes place via the RJ12 cables supplied. The sensors are addressed via a DIP switch, whereby addresses between 1 and 256 can be assigned. A separate adapter plate is supplied for attaching the sensor to profiles and similar structures.

I/O Module

The connection centre

The I/O module interacts with the control unit. All connections and functions are wired here. Additional end devices such as screwdrivers, pushbuttons or robots can be integrated via this module. There are 16 inputs and outputs available.

Control

The communication tool

The Pick by Light control connects the software with the sensors in your application. You can define all the functions in the software, but the actual implementation is carried out by the control unit. All Pick by Light sensors are connected to this control unit. A single control unit can process up to 4 x 256 sensors. The connection to the control unit is made via a USB port on a Windows computer.

Touchscreen Monitor

Step by step through the assembly process

The SETAGO® software is controlled via a touchscreen monitor. You have the option of customising and editing all work steps according to your requirements. The monitor presents the work instructions step by step and guides you through the installation process. The monitor can be positioned independently using a wall bracket.

Button housing

Navigation through the work steps

Use the pushbutton housing to navigate through the various work steps. You can either switch forwards or return if a step needs to be repeated. This navigation can of course also be carried out via the touchscreen monitor. However, the pushbutton box offers the advantage of being placed directly next to the work process, which is both ergonomic for assembly workers and saves time. Foot pedals can also be used as an alternative option.
