SMX modular - Safe masters and slaves in the modular series
The Allrounder

The all-rounder in the SMX series offers a standardised solution for all machine safety tasks. With the PLC commands and more than 280 type-tested safety functions, even complex machining and machining centres can be secured simply and transparently.

The SMX Modular's decentralised system architecture with its master, I/O and technology functions allows a high degree of expansion with up to 32 slaves and just as many drive axes.

The series at a glance

  • With integrated OPC UA-Server and Gateway to sensor /actuator level for status and condition information
  • Simple process data exchange via OPC UA publisher/subscriber services
  • Access for service and Asset services
  • Simple and transparent programming and parameterization via SafePLC²
  • Flexible use due central and decentral expansions
  • Drive monitoring for up to 12 axes with extended encoder functionality
  • Safe cross communication for data exchange between multiple base devices via ethernet-based protocols with SMMC (Safe Master - Master Communication)
  • Suitable up to PL e (EN ISO 13849-1) and SIL3 (IEC 61508)
