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).
Just as with DeviceNet, DeviceNet Safety-compliant devices from third-party
vendors can be connected to a DeviceNet Safety network. Also, DeviceNet-
compliant devices and DeviceNet Safety-compliant devices can be combined
and connected on the same network.
By combining DeviceNet Safety-compliant products, a user can construct a
safety control/network system that meets the requirements for Safety Integrity
Level (SIL) 3 according to IEC 61508 (Functional Safety of Electrical/Elec-
tronic/Programmable Electronic Safety-related Systems) and the require-
ments for Safety Category 4 according to EN 954-1.
