tina12e1 (0106) PEG100-D.ga
The PEG100-D are equipped with a fieldbus interface
DeviceNet. Thus, process automatization devices can
easily be interconnected.
1.1 DeviceNet - Interface
The fieldbus-system DeviceNet is described in the Devi-
ceNet specification of the Open DeviceNet Vendor Asso-
ciation (ODVA). The technical and functional features of
the DeviceNet Standards are specified herein.
The PEG100-D have the functionality of DeviceNet
Group 2 Only Slaves.
