1: AS-INTERFACE Introduction This chapter describes general information about the Actuator-Sensor-Interface, abbreviated AS-Interface. AS-Interface is a type of field bus that is primarily intended to be used to control sensors and actuators. AS-Interface is a network system that is compatible with the IEC62026 standard and is not proprietary to any one manufacturer.
1: AS-INTERFACE AS-Interface System Requirements Master The AS-Interface master controls and monitors the status of slave devices connected to the AS-Interface bus. Normally, the AS-Interface master is connected to a PLC (sometimes called ‘host’) or a gateway. For example, the MicroSmart AS-Interface master module is connected to the MicroSmart CPU module.
1: AS-INTERFACE Main Features of AS-Interface V2 with Slave Expansion Capability The AS-Interface is a reliable bus management system in which one master periodically monitors each slave device connected on the AS-Interface bus in sequence. The master manages the I/O data, parameters, and identification codes of each slave in addition to slave addresses.
1: AS-INTERFACE Quantities of Slaves and I/O Points The quantity of slaves that can be connected to one AS-Interface bus is as follows. • Standard slaves: 31 maximum • A/B slaves: 62 maximum The limits for slave quantities given above apply when the slaves are either all standard slaves or are all A/B slaves. When 62 A/B slaves (with four inputs and three outputs) are connected, a maximum of 434 I/O points (248 inputs and 186 outputs) can be controlled over the bus.
