Abstract
ASCO/Joucomatic GmbH & Co designs, produces and sells pneumatic and fluid equipment.
The company produces and sells pneumatic components and automation components on the European and international markets with market shares of 6 respective 2%.
Typical products of ASCO/Joucomatic are Proportional Pressure Valves, MicroValves, Custom Made Valves and Valve Islands with several Fieldbus Interfaces (BUSLINK products), general purpose valves, cylinders and pneumatic accessory. The existing products were based on analogue, digital and mixed signal printed circuit boards, partially with microcontroller.
The aim of the AE is realisation of a mixed signal ASIC for data communication in a connection system of valve islands. A versatile system allows to combine different numbers of valves into a valve island. A small system allows to directly interface valves to a communication system, which is very important to benefit from the advances in modern valve technology. With a small and powerful communication and control system valves can be easily mounted to moving parts. The system can connect up to 127 bi-stable valves (2 coils per valve) with a two wire cable for data communication and power supply. Therefor the area of the mixed signal ASIC is split in 20 % power, 30 % digital and 50 % analogue circuitry.
The existing valve islands can hold only 16 bi-stable valves which are connected through a printed circuit board (PCB). The variety of valves and different numbers of valves per island require up to 42 different types of PCB to connect valve islands and control the individual valves. These 42 PCB’s can be substituted by a single PCB with a mixed-signal ASIC, which has been realised during this project. The new system will reduce wiring costs in a machine or plant and will be more flexible for extension. The costs of the new components are only 75% of the existing product.
The duration of the AE was 16 month and the proposed costs are 122 KEuro. The start of the AE was 1.3.97 and last until 30.6.98. The payback period will be 2 years after the product is on the market and the return on investment approximately 300%.
