Safety PLC - Safety controller
Safety controller and Safety PLC
A safety controller or safety PLC has an important role within a safety system. Potential hazards of machines or installations must be managed safely. Safety switches monitor the status of safety devices. When an unsafe situation is detected, the safety relay will give a signal that switches off the energy to the potentially dangerous machine or safely interrupts the safety circuit.
Multiple safety switches
A safety PLC can manage one or more safety switches, such as safety light curtains, photocells, emergency stops, laser scanners, electromechanical switches, magnetic switches, lock safety door switches, RFID switches, safety mats and so on. A safety relay has two functions; on the one hand the processing of the signals from the connected safety switches and components and on the other hand the safe and reliable interruption or disconnection of potentially dangerous machine (functions).
Functions safety PLC
In addition to 'standard' safety relays, there are also wireless and safety PLC's. In applications where there is little or no room for cables, a wireless safety relay can offer the solution. If it is desirable for only a part of the connected safety switches to switch off or fall into emergency stop when an unsafe situation is detected, a safety PLC provides the solution.

Mosaic M1S COM security PLC from ReeR
The Mosaic M1S COM by ReeR Safety is a powerful main module with integrated fieldbus interface protocols, including Ethernet IP, EtherCAT, Profinet, and Modbus TCP. This makes it possible to link safety functions to system processes and enable external connections without the need to purchase separate communication modules, making the ReeR M1S COM a cost-effective solution.
With four selectable fieldbus interface protocols via the MSD configuration software, the Mosaic M1S COM is the ideal choice for connecting safety functions to system processes.
Furthermore, this main module has four OSSD safety outputs (PLe) or two pairs of OSSD outputs (PLe) and has the capacity to process 128 logical operators. This allows safety applications to be realized even more effectively.

Software (MSD) - Safety PLC
The safety PLC Mosaic from ReeR Safety is easy to program with the free supplied software. The image on the right shows the basic screen of a security system entered in the MSD software. The software works through 'drag and drop'. All different parts can be dragged and moved.
Project reporting and log files
The ReeR Mosaic M1 main module has a USB connection that allows you to connect the main module to your PC via a USB cable. The software allows to validate the software design in the form of a simulation and project report. The project report contains the name of the project, configuration, safety information (PFHd, MTTFd, DCavg) and the modules, resources and parts used. The software generates a log file with the date when the project was created with the related checksum (CRC 4-digit hexadecimal identification) which is stored in the Mosaic M1 module.
Mosaic Configuration Memory
If it is a standard security system or largely standard, the 'Mosaic Configuration Memory' is a time-saving solution. A previously programmed security system can easily be transferred to another ReeR Mosaic M1 module by means of a memory card.
