Top performance for small applications
Savings of up to 50% with small machines and systems
With the AS-i Power24V innovation, Siemens now offers an automation expansion which is particularly suitable for compact machines (e.g. machine tools) and applications inside the control cabinet. The utilization of already employed 24V power supply units in connection with a data decoupling module facilitates the cost-favorable realization of AS-i networks with expansions of up to 50 m.
With the help of the data decoupling module, data and energy can be realized on a single line in the AS-i network. Even several data decoupling modules for multiple AS-i networks can be connected to one power supply unit – which results in an additional cost advantage.
Advantages at a glance:
Cost and space savings thanks to elimination of the 30V AS-i power supply unit
Efficient utilization of one power supply unit for several AS-i networks
Increased degree of standardization in small systems
Reduced getting-started costs for AS-Interface
Utilization of present AS-i network advantages, e.g. high data quality, extended diagnostics and maintenance information, integrated ASIsafe technology, unlimited number of connectable slaves
The power supply units centrally supply the AS-i network and the connected slaves with energy. They form an integral part of an AS-Interface network and, in combination with data decoupling, facilitate the simultaneous transmission of data and energy on the same two- wire line.
AS-Interface networks can be very comfortably directly connected to the SIMATIC control or Distributed I/0s. For this purpose, so-called CPs or CMs are available. Integration is just as easy as with other expansion modules of SIMATIC by Siemens.
Besides direct integration, AS-Interface can also be employed in a distributed manner as feeder for superior bus systems. With the help of AS-i gateways (links), subordinate AS-i networks can be completely assembled and commissioned even before the central control is completely programmed.
Up to 62 standard slaves or 31 safe slaves can be connected to an AS-i network for data exchange with the superior AS-i master. Our portfolio of AS-i slaves ranges from simple I/O modules down to motor starters and frequency converters.
Our portfolio of system components comprises products for AS-i network analysis, AS-i slave addressing as well as range extension. Numerous further accessory components such as distributors, M12 feeders, mounting plates and cable end pieces complete the product portfolio and support a very easy and flexible assembly of the entire AS-i system.
Depending on your individual requirements, you can chose between the "small" ASIsafe Solution local and cell- spanning, system-wide ASIsafe integration with the help of the SIMATIC AS-i F-Link as gateway between ASIsafe and PROFIsafe beneath a fail-safe control.
SIMATIC STEP 7 / TIA-Portal
From SIMATIC STEP 7 V5.4, AS-Interface modules by Siemens can be configured in your system with even greater comfort. STEP 7 comprises a slave selection dialog via which the modules are integrated in the respective S7 project with a mouse-click. All slave-specific profile settings (I/O and ID codes) are automatically carried out. The modules are parameterized via selection lists in plain text, doing away with the search for parameter bits in the operating instructions. A comprehensive module description text eases system documentation.
The MSS ES parameterization software forms a central part of the modular safety system (MSS) and supports the rapid and easy parameterization of safety functions as well as comprehensive diagnostics options.
The ASIMON PC software serves the configuration of the AS-Interface safety monitor. Vie the software's online function, the current state of the configured logic blocks can be read out on site and monitored in the fully graphical diagnostics view. The green/yellow/red color changeover of the blocks and connection lines provides the desired status information in an intuitive manner. This function offers valuable advantages particularly in terms of commissioning and troubleshooting.
The ASIMON V3 software offers numerous further user benefits, including fully graphical circuit diagram generation of the safety logics in transparent window technology, safe coupling of two AS-i networks, filtering of short-term one-channel interruptions in the sensor circuit, management of user- specific blocks, graphics printout of the safety logics, gradual teaching or manual entry of the ASIsafe code tables, freely selectable index assignment for integrated PLC diagnostics, immediate state signaling of relay outputs to the PLC and many further valuable functions.
SIMATIC HMI / WinCC flexible
AS-Interface provides comprehensive diagnostics data which can be effortlessly and immediately read out by the SIMATIC STEP 7 system. These data can be interconnected in the STEP 7 program for responding to system states and/or output on an operator panel for rapid fault rectification.
For this purpose, a fully functioning package of function blocks for S7-300/400 and pre-defined screens for the color graphic displays in 6", 8" (10") and 15" version are available. The screens can be scaled via WinCC flexible for other monitor sizes. The graphics comprise the diagnostics of AS-i master and slaves.
The following AS-i masters and links are supported:
DP/AS-i Link Advanced
DP/AS-i Link 20E
IE/AS-i Link PN IO
Block Library for PCS 7
The AS-Interface block library for PCS 7 can be integrated in the SIMATIC PCS 7 process control system, expanding it by the option of AS-Interface system integration
