The master with gateway-function controls the AS-Interface system and transmits process data to all types of higher-level control in a standardized I/O map. The AS-Interface adopts the role of a conventional I/O card in the controller, which allows a simple changeover to the AS-Interface system. The stainless steel master/gateway manages communication with the slaves and informs the PLC of faults. All diagnostic information from the field I/O and the safety system can be transmitted to a higher level control system. The safety logic of a master with safety monitor can be set either by a safe PLC or decentralized via the configuration software VAZ-SW-SIMON +.
Each AS-Interface segment requires one AS-Interface power supply (VAN-…) with 30.5 V DC voltage and data decoupling to provide power and send modulated signals along a cable without interference. Control cabinet power supplies are available with 2.8 A, 4 A, or 8 A for high efficiency. The AS-Interface K19 is a NEC Class 2 power supply. The ground fault monitor is already integrated in the 4 A K27 AS-Interface power supply. With appropriately equipped master / gateway you can operate up to two AS-Interface segments with a standard 30 V DC power supply.
"AS-Interface Safety at Work” relates to safe communication in the AS-Interface network according to the most recent Machinery Directive. The highest safety class SIL3/PLe can be achieved with this globally utilized safety system, allowing safety systems without the need for a safety PLC. All known safety devices can be connected directly to the AS-Interface segment via modules or as an integral solution. The AS-Interface safety concept can be modified flexibly and decentrally. Logical links can be defined through the configuration software VAZ-SW-SIMON+.
KE series control cabinet modules are available in various sizes with different numbers of terminal connections.
The G10 is the world’s smallest IP68/69K AS-Interface module; the one-piece housing mounts quickly and securely using a single stainless steel screw. We also offer safety modules in the G10 design.
G11 field modules offer an innovative seal concept in a robust, compact, round design and are particularly suitable for machine builders and harsh and process environments. In the G11 design, we can also offer you various analog modules.
G12 flat modules are extremely easy to connect and can be replaced with a minimum of fuss in the event of a fault. The G12 has a one-piece housing with a cable guide that reduces installation times considerably.
Pepperl+Fuchs offers a wide selection of sensor types with integrated AS-Interface.
Different designs are available with NC or NO contact function. Sensors with AS-Interface provide additional functions such as a failure warning indication and coil breakage indication.
On photoelectric sensors, parameters can be used for light-on/dark-on switching.
Pepperl+Fuchs rotary encoders are fitted with 4 AS-Interface chips that enable the transfer of 16 bits during every cycle.
Special sensor designs with two input signals for “open”/ “closed” are available for position monitoring. Power for the valve solenoid and the sensors is supplied from AS-Interface.
Vibration forks with integrated AS-Interface are used for fill level monitoring.
Operating buttons with a flat cable connection and integrated indicator light are provided for manual operation. System components are controlled easily using the START/STOP buttons and the operator is provided with visual feedback.
Integral AS-Interface illuminated pushbuttons are also available for installation in the control panel. A maximum of 4 indication elements can be controlled via a AS-Interface module. Stack light modules are available in 5 colors with 3 signal horns and can be assembled as required.
G10 splitter boxes are required for flat cable branching, connecting modules, and connecting integrated AS-Interface end devices. A large selection of models with ECOLAB approval and IP68/69K degree of protection are available.
Itʼs easy to commission your AS-Interface system with the AS-Interface handheld because each AS-Interface device requires an address to communicate with the gateway on the bus, allowing one-handed operation and easier addressing. The handheld comes in a case together with a power supply and programming cables.
The flat cable for AS-Interface and AUX is available in 100 m spools or 1000 m rolls with 1.5 mm², 2.5 mm² in various materials.
AS-i Control Tools software speeds up network disgnostics and SIMON+ software diagnoses AS-Interface safety configurations.
Pepperl+Fuchs has been producing M8 and M12 connectors for more than 10 years A large variety of products always provides the perfect solution.
