  • Page 43: System Configuration

    DeviceNet Safety System Overview DeviceNet is an open-field, multi-vendor, multi-bit network, which combines the controls in the machine and line control levels with information. The DeviceNet Safety network adds safety functions to the conventional DeviceNet standard communications protocol. The DeviceNet Safety concept has been approved by a third-party organization (TUV Rhineland).

    Controllers with unit version 1.0 or later can perform safety I/O communica- tions as a Safety Master for a maximum of 32 connections (32 Slaves) with up to 16 bytes per connection. The NE1A-series Controllers support two protocols, single cast and multicast (broadcast), for safety I/O connections.
