The MGB2 from Euchner now features more networking options and the integrable CKS key system as a submodule. It protects machine and installation safety doors and fences during hazardous machine movements. The MGB2 consists of a guard locking module, the contained submodules for controls and indicators, optional expansion modules and the bus module for connecting to PROFINET/PROFIsafe – and now also to EtherCAT P/ FSoE. It is the world’s first guard locking device for the safe EtherCAT. The bus module acts as the system’s “head.” All information from the connected modules comes together here and is transferred to the installation’s control system. Comprehensive diagnostic and communication functions in the form of EtherCAT or PROFINET messages and the integrated web server provide a fast and detailed overview of the device status. The control system, in turn, sends its signals via the bus module to the connected system modules to control guard locking or activate a lamp, for example.
