Safety system for e.g. monitoring safety-relevant area, has modules, where one module is switched in energy saving and operation modes by local events or rest and roll instructions or instructions transmitted by other module, respectively
The system has safety modules (10-20) that are connected to a network and transmitting data over the network, where one of the modules is switchable in an energy saving mode by a local event or a rest instruction generated by the local event or by the rest instruction transmitted by other safety module. The module is switchable in an operational mode by another local event or roll instruction generated by the latter local event or by the roll instruction transmitted by the latter module. The former event is interference of energy supply.
