Accessing Devices by UDP/IP

Safety controls can be monitored by accessing
devices on the DeviceNet Safety network using the
UDP service from a general-purpose controller on
the Ethernet network (e.g., a PLC or computer).

Devices on a DeviceNet or DeviceNet Safety network can be accessed from
general-purpose controllers (e.g., PLCs or computers) in an Ethernet network
using UDP/IP frame message communications via an ED Router.
This enables monitoring a DeviceNet or DeviceNet Safety control system via
Ethernet from a machine controller or monitor computer that does not support
a DeviceNet interface. This can be used to easily add a DeviceNet Safety con-
trol system to an existing system.
