History and development of Pick-to-Light
The Pick-to-Light story
The history of Pick-to-Light systems goes back to the beginning of 1990. The first Pick-to-Light displays were designed as "shift registers" and connected to a collective zone controller. The keystrokes were registered via a terminating resistor, evaluated and sent back to the controller. The Pick-to-Light features were very limited.
At that time, communication between the PC with 286 processor (operating system DOS) and the zone controllers was handled via many RS485 channels (special hardware). Because of the long lines, the communication was slow and the cabling was very complex. That was at that time ...
Today, the Pick-to-Light systems are structured quite differently. Each display is equipped with its own microprocessor and has many diagnostic and individual functions. There are many versions with different tasks. The communication between the controllers is based on TCP/IP. The entire process logic is mapped in the LUCA-Server and is very customizable. Unfortunately, there are still market suppliers who continue to use the old unreliable technology.
