These devices perform a cyclic interrogation of the slaves via a polling procedure and represent the link to the higher level system in the form of a decentrally operating, flexible and fast control unit. The devices are also available with a control function (Integrated PLC with inputs, outputs, timers, and counters) for autonomous operation. Masters are available in various versions and construction types, for example with a large graphics display for on-site diagnosis. These cover not only peripheral faults, even statistical faults can be evaluated via an internal fault counter and used for trouble-shooting if necessary. Of course, all data can also be transferred via the field bus interface for control purposes. Addressing and parameter assignment (On initial installation, for example) can take place directly on the master/gateway. There are also commissioning tools available, for instance the AS-i Control Tools software, VAZ-SW- ACT32. This software package allows simple, quick, and easy commissioning of the AS-Interface network via the serial interface of a PC. Various interfaces are available for connecting the higher level control system: Serial interface (RS 232) PCI bus for direct connection to a PC Field bus interface with the gateways (For all current field bus systems, e. g. PROFIBUS DP, DeviceNet, INTERBUS, etc.) A gateway consists of two parts: The AS-Interface master (e. g. to AS-Interface specification V2.1) for management of the AS-Interface network. The interface to the higher level field bus system (e. g. as PROFIBUS slave) for transfer of the data to the control system. For field applications Pepperl+Fuchs can supply masters/gateways in protection class IP67 in the G4 housing. These devices are ideal for decentralisation with AS-Interface, since the devices can be installed close to the application. The restriction to 100 m of cable is of no great consequence and the large distances can be bridged using the higher level field bus system. The unified menu structure and philosophy of the masters/gateways simplifies operation despite a large number of devices. Master/Gateways designed to specification 2.1 have the type codes VBM... oder VBG..., while devices designed to specification 2.0 have the codes VAM... or VAG... Devices with codes VBG-...-D oder VBG-...-DMD are equipped with a large graphics display for extra ease of operation. For your peace of mind: This AS-Interface logo indicates that the AS-Interface devices are "Certificated" products. It's there to reassure you that you will experience no negative mutual interference effects from AS-Interface devices in your system. Subject to reasonable modifications due to technical advances.
