ASIsafe makes it happen. The safety-related version of AS-Interface facilitates the transmission of standard and safe data on one and the same bus system – TÜV-certified, up to PL e / Cat. 4 or SIL 3. No other supplier offers ASIsafe in such a scalable degree: From small safety islands to system-wide Safety Integrated architectures with superior safe PLC.
Advantages at a glance:
Direct integration of safety-related components (e.g. EMERGENCY-STOP, protective door) in the AS-Interface network
The MSS supports the implementation of safety-related functions independently of the controller or also facilitates full integration in the safety control system using the SIMATIC AS-i F-Links.
Attainable safety level up to PL e / Cat.4 / SIL 3
Full compatibility with all other AS-Interface components in accordance with IEC 62026-2
The modular SIMATIC AS-i Links based on ET 200SP enables AS interface networks to be easily connected fail-safe to safety controllers such as SIMATIC or SINUMERIK. With the SIMATIC AS-i F-Links, the advantages of AS-i can also be utilized in complex safety applications. They facilitate the application of AS-Interface, for example under fail-safe SIMATIC or SINUMERIK controls. Acting as links in bus-based safety technology, they support the ASIsafe telegrams' transfer to the PROFIsafe protocol – in both directions. As usual, the detection of safe signals is realized by means of rugged ASIsafe slaves. The safe data are processed in the control in parallel with the standard data's processing. As a result of safe processing, the control issues safety-related disconnection commands which are transmitted to the safe actuators, e.g. motor starters, via PROFIsafe. Furthermore, the safety-related signals can be further processed back on the ASIsafe level, for example for the disconnection of safe AS-i outputs in load feeders.
For large quantity structures of safe sensors and actuators
For expansive and complex safety logics
For a large number of safety-related disconnection circuits
For safety-related further processing on the superior field bus level
The ASIsafe Solution Local requires only few components: An MSS or a safety monitor and safe slaves. Neither fail-safe PLC nor special masters are required. The MSS monitors safe sensors (e.g. EMERGENCY-STOP), evaluates them in accordance with its parameterized safe logics and ensures their safe disconnection. Disconnection is realized in a distributed manner via ASIsafe in connection with safe AS-i outputs or via safe outputs integrated in the device.
MSS and safety monitors represent the best choice:
with medium and small quantity structures of safe slaves,
with a small number of safe disconnection circuits
when safety technology and safety-related processing are to be separated from the superior field bus level or control in a targeted manner
with a manageable number of safe logical interconnections
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.
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.
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.
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.
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.
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 S7-300/400/1200 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 for other monitor sizes. The graphics comprise the diagnostics of AS-i master and slaves.
