Mosaic from Reer is a modular, configurable safety controller for protecting machines or even entire plants. Mosaic is capable of monitoring several safety sensors and commands, such as safety light curtains, laser scanners, photocells, mechanical switches, mats, emergency stops, two-hand controls, concentrating management of these in a single, flexible device.
Thanks to its modular design, parts of the Mosaic System can be decentralised in remote cabinets with respect to the master unit.
Mosaic offers numerous advantages compared with safety solutions based on traditional components, such as relay type safety modules, as it:
• Reduces the number of components and therefore footprint and wiring
• Promotes faster electrical cabinet construction
• Affords the necessary logical configuration using a single, simple programming software, facilitating modifications by machine designers
• Makes it possible to set up tamper-proof safety systems
• Simplifies machine maintenance through the MCM memory card, which can be used to transfer the configuration program to a new Mosaic in just a few simple steps.
The MSD (Mosaic Safety Designer) software, installed on a PC, can be used to create complex logical conditions using logical operators and safety functions, such as muting, timer, counters, memories, etc. via an easy, intuitive graphic configuration interface. Configuration data are transferred to the master unit via a USB link.
Mosaic from Reer conforms and complies with the following directives and standards:
• 2006/42/EC “Machinery Directive”
• 2004/108/EC “Electromagnetic Compatibility (EMC)”
• 2006/95/EC “Low Voltage Directive (LVD)”
• CEI EN 61131-2: “Programmable Controllers, part 2: Equipment requirements and tests”
• EN ISO 13849-1: “Safety of machinery: Safety-related parts of control systems –
• Part 1: General principles for design”
• EN ISO 13849-2: “Safety of machinery: Safety-related parts of control systems – Part 2: Validation”
Mosaic comprises a master unit M1, configurable via the MSD graphic interface – provided with each Master unit at no extra cost – and a maximum of 14 expansion units connectable to M1 via the MSC (Mosaic Safety Communication) proprietary bus.
Expansion units are also available that permit connection for diagnostics purposes to the most common industrial Fieldbus systems: MBP (Profibus DP), MBC (CANopen), MBD (DeviceNET), MBEI (Ethernet IP), MBEC (EtherCAT), MBEP (PROFINET), MBU (Universal Serial Bus).
The Mosaic system can be equipped with a maximum of 128 inputs and 16 OSSD pairs. The master module and expansion units communicate via the 5-way MSC, which is physically located on the back of each module.
