product news Improved data transfer, diagnosis via optimised bus termination. Permanent monitoring of the message quality, display of critical states by LED “traffic lights”. AS-i tuner: Active bus termination with teach-in phase for adaptation to AS-i networks. Protection rating IP 67 for direct installation in the field at the end of the AS-i cable. Use in conjunction with repeaters possible, overall length up to 750 m. Easy mounting with flat or round cable lower part. Introduction The communication of an AS-i network can be considerably improved by the connection of a suitable terminating resistor. It is composed of an inductor, resistor and capacitor. This leads to the effect that an AS-i network can be operated with a cable length of up to 100 m. As flexible tree, ring, star and line topologies are possible with AS-i, there are no clear rules as regards the possible cable length. Empirical measurements with different arrangements have shown that up to 250 m are possible in many networks. To ensure optimum effect, the AS-i tuner is mounted at the end of the AS-i cable which is furthest away from the AS-i power supply. The AS-i tuner has a microprocessor which performs a quality assessment of the AS-i network setting the impedance at one press of the button. fluid sensors and diagnostic systems position sensors networking and control Typical applications: • Use at the end of a cable if more than 100 metres of AS-i cable are to be used • In nested arrangements mounting furthest away from the AS-i power supply • For increased safety with respect to interference in Safety at Work applications • If incorrect messages occur frequently and the cause cannot be identified • Extension of the AS-i cable with repeaters to up to 750 metres between two slaves Networking and control The AS-i tuner: optimum setting, increased safety, longer cable. Industrial communication Networking and control Advantages and customer’s benefits. • Basic function of the AS-i tuner The AS-i tuner is based on the tried and tested EMS ClassicLine family. Both flat or round cable lower parts can still be used. The AS-i voltage is in addition on an M12 socket. Tuning is not made automatically but is started by means of the teach-in button. By this process the bus termination impedance is changed until AS-i communication has reached its optimum. This may be useful with Safety at Work applications, with bus cable lengths of more than 100 m or with the use of screened bus cables. • Bus diagnosis using the AS-i tuner The AS-i tuner incorporates bus diagnosis with a qualitative display of the communication and is thus particularly suited for difficult conditions and for service use. The three LEDs operate to the “traffic lights” principle (red/yellow/green) and symbolise the excess gain of the data exchange. When the TUNE button has been pressed, the quality should improve so that only the green LED is lit. • Extension of the cable using repeaters Considerably greater distances can be bridged using AS-i repeaters and the tuner. The length is extended by up to 200 m instead of the 100 m possible as compared to the classical AS-i wiring (see drawing below). At any rate a bus diagnosis to determine the message quality should be made before and after mounting of the tuner.
