Pico DeviceNet Interface
The 1760-DNET communication module has been developed for
automation tasks with the DeviceNet field bus. The 1760-DNET acts as
a ’gateway’ and can only be operated in conjunction with Pico and
Pico GFX-70 controllers.
The system unit consists of the Pico control device and the
1760-DNET DeviceNet gateway and operates exclusively as a slave
station on the DeviceNet fieldbus system.
System Overview
The DeviceNet slaves are integrated into a DeviceNet fieldbus system.
