SIMATIC FS400 light curtains and arrays

Transcription

1 Overview The RG78 7 processing units form a flexible product family of interface modules for light curtains and light arrays. The modular design of this series can be used up to type to IEC/EN696-,-. These units expand the functionality of the light curtains and arrays to include startup/restart inhibit and contact control as well as cycle control and muting depending on the version. This product family also offers an extensive range of additional functions such as early error warning for the relay contacts, a PC diagnostics function as well as many signaling outputs to a higher-level controller.

16 SIMATIC FS600 laser scanner Overview Our optical distance sensors provide perfect all-round protection to type in accordance with IEC/EN 696. In an operating field of 90 and over a distance of up to.0 m (up to 5 m in non-safety-related applications), the laser scanner reliably senses every object and every person. And it works so simply: The distance sensor emits light pulses at regular intervals. If they hit an obstruction, the sensor receives the reflected light and evaluates it. If this is evaluated as the predefined area to be protected, a Stop function is triggered. With up to four programmable protective field pairs that can be selected during operation, our laser scanners can be optimally adapted to any application on machines, production robots, conveyor systems or vehicles. Different variants support optimal integration in the automation system: Whether conventionally in the safety circuit, over PROFIBUS with PROFIsafe or over AS-Interface with ASIsafe. Application Horizontal danger zone protection Introduction Route monitoring for automatic guided vehicle systems NSC0_0060 SF SF SF SF Reliable detection of persons and objects approaching the vehicle. The laser scanner offers a greater protection range than bumpers and, therefore, permits higher speeds. Collision protection for shifting units c c b SF SF NSC0_0069 Reliable detection of persons and objects in danger zones around machines and plants. Flexible programming of almost any protection and warning zones. Horizontal danger zone protection with more than one protective field NSC0_006 Reliable protection of persons in the path of the vehicle. Objects in the path of the vehicle are detected in good time and damage to the vehicle or its load is prevented.

17 SIMATIC FS600 laser scanner Introduction Access protection by means of entry control Access protection by means of entry control can be used when the entry location to a machine or to a danger zone can be precisely defined and when no other unsecured access to this area exists. The laser scanner is preferably mounted above the entry point, aligned vertically. To protect the protective devices, laser scanners and fence from inadvertent adjustment and malicious manipulation, the protective fields of the laser scanners must be defined using reference contours. In this operating mode, the scanner uses the sampled environment as a reference and can therefore monitor changes to the structure of the protective equipment as well as each individual measurement to detect an entering person. Securing danger zones by means of hand and arm guards If a machine operator has to be close to the dangerous movement or if the operator coordinates the positioning and removal of workpieces at the machine, danger zone protection must be implemented at the machine. A protective device must be used to guard these danger zones. The laser scanner is approved for securing danger zones by means of hand and arm guards and can, also in combination with protective field changeover, ensure flexible work safety. To protect the protective devices, laser scanners and the screens (attached to the sides as a reference and as additional access protection) from inadvertent adjustment and malicious manipulation, the protective fields of the laser scanners must be defined using reference contours..

18 SIMATIC FS600 laser scanner Introduction Function The laser scanner is an optical, contact-free surface scanner designed primarily for operator protection. Four protective field/warning field pairs Four variable protective field pairs for the personnel protective field and warning field, which can be easily set on the PC, ensure that the laser scanner can be adapted to suit any requirement. E Sc Reflection SF SF SF SF NSC0_006 Using a laser diode with transmission optics, the laser scanner continuously generates bundled light pulses that are scattered throughout the operating range by an integrated rotating mirror. If objects or persons enter the field, it evaluates the reflected light pulses and continuously calculates the exact position coordinates on the basis of the light propagation time. If the defined personnel protective field is penetrated, the laser scanner stops the machine immediately (within the system response time). The Stop function is reset when the protective field is free again, either automatically or following acknowledgement (depending on the operating mode). The operating range of the laser scanner spans 90 and is subdivided into angle segments of NSC0_0065 Only personnel protective fields are shown It can be implemented in stationary applications (machines and installations) or mobile applications (vehicles, automatic guided vehicle systems, or shifting units). In the case of a robot, for example, different operating ranges can be protected, whereby the laser scanner operates in succession with regard to time and space. In the case of automatic guided vehicle systems, four programmable protective fields can be protected (e.g. rapid travel, slow travel, turning left, turning right). LSsoft operator software Thanks to the PC operator software LSsoft, it could not be easier to optimize the laser scanner settings. The following functions have been integrated: User-friendly configuration of the protective field using a PC or laptop Configuration of additional functions, such as protective field selection, restart inhibit, etc. by means of a software wizard Comprehensive range of displays, e.g. defined protective fields, current scan contours, system settings, etc. reliable, password-protected access with different authorization levels Executable under Microsoft Windows 95/98/NT/000/XP The operator software is supplied with the laser scanner. 5 NSC0_ The scan rate is 5 scans/second, i.e. one light pulse every 0 ms in each segment. A special algorithm ensures that objects larger than 70 mm (this corresponds to the scanner resolution) can be reliably detected and that contamination (e.g. dust) does not reduce system availability. The laser scanner detects people (even if they are wearing dark clothing) at a distance of up to m (failsafe). People or objects can, however, be detected at a distance of up to 5 m so that a warning can be output, for example (not safety relevant). Siemens FS /9
