UM EN FLX ASI SYS PRO INST 1.4.1 Easy Handling In the AS-Interface system, the binary I/O device is addressed via the control system (PLC) in the same way as when using I/O boards and a cable harness. The direct addressing of devices and the simple electromechanical structure (penetration technique, tree structure) also simplify retrofitting and the conversion of an AS-i system. No special knowledge of the system, e.g., for service and maintenance, is required in order to ensure a smooth transition from the previous star cabling to serial bus technology. The unerring self-diagnostics of the AS-i system significantly contribute to the reduction of system downtimes. For example, when replacing a faulty slave device it is not necessary to assign a new address or modify the PLC program. The AS-Interface system supports the replacement of a slave through automatic addressing. 1.4.2 Information Content of Data Telegrams The AS-Interface system is optimized for networking the most basic devices using just a few items of bit information per device. The data telegrams are therefore very short and have a very simple structure. This means that the electronics to be integrated in the devices can be created cost-effectively. The AS-i telegram contains a maximum of four data bits for information exchange from the control system to the slave (output data) and from the slave to the control system (input data). Both the input data and the output data are updated in each cycle. For more complex devices, e.g., analog devices, larger amounts of data can also be transmitted. This data must be split and transmitted in several consecutive cycles in multiplex mode. 1.4.3 Communication Principle The AS-Interface system is a single master system. A bus access method is used for communication, which ensures a defined and fast response time. Communication is always initiated by the master, the slaves only respond to master requests. The master communicates cyclically with all devices, which are addressed using an address that is programmed once. A master cycle consists of the requests for all connected devices. This communication method is known as cyclic polling. 1.4.4 Time Response onlinecomponents.com The cycle time of the AS-Interface system is deterministic and proportional to the number of devices. A time of 150 microseconds is required per device. At full system configuration with 62 devices, the cycle time is 10 milliseconds. At the end of this time, all information that was transferred from the control system to the Fieldline Extension AS-Interface system (the master) has arrived at the slaves. Within this time all input data has also been read. 1-4 PHOENIX CONTACT 7513_en_01
1.5 AS-Interface standardization Fieldline Extension and the AS-Interface System 1.5.1 AS-Interface specification The AS Interface specification defines the complete AS-Interface system and guarantees standardization of all system components. Three AS-Interface specifications have been published since AS-Interface has been introduced in the mid-90s. Standard slaves Slaves with extended addressing Table 1-1 Specification 2.0 describes standard slaves. Addresses from 1 to 31 can be assigned to standard slaves. This limits an AS-Interface network to 31 AS-Interface slaves. Specifications 2.1 and 3.0 describe slaves with extended addressing. Addresses from 1A to 31A and 1B to 31B may be assigned to AS-Interface slaves according to these specifications. Thus, the possible number of AS-Interface-slaves in a network is doubled compared with specification 2.0. The currently valid specification is the "Complete Specification" version 3.0, revision 2.0 dated July 09, 2008 (as of August 14, 2009). AS Interface specification overview 2.0 2.1 3.0 31 slaves, maximum 62 slaves, maximum 62 slaves, maximum 31 single slaves or 31 A slaves (can be mixed) 31 A slaves and 31 B slaves (single slaves will also be supported.) 31 A slaves and 31 B slaves (single slaves will also be supported.) 4 inputs and 4 outputs 4 inputs and 3 outputs 4 inputs and 4 outputs Master profile M0, or later Master profile M3, or later Master profile M4, or later No "Combined Transaction" "Combined Transaction" "Combined Transaction" Support of "Combined Transaction" Type 1 Support of "Combined Transaction" Type 1 to Type 5 onlinecomponents.com 7513_en_01 PHOENIX CONTACT 1-5
