Ethernet
The T2N CPU modules (PU235N and PU245M) have
a built-in Ethernet interface (10BASE-7).
Through Ethernet, the T2N can communicate with a
computer, a workstation, or another T2N,

DeviceNet
DeviceNat is an open standard field network. Many
DeviceNet compatibie products {ODVA certified) are
available from other manufactures.
The DN211 is a DeviceNet scanner module for the
T2E/T2N. The DN211 can read/write data to any
other manufacturer’s OVDA certified devices, such
as I/O blocks, Inverters including Toshiba's G3, air
valve manifolds, sensors, etc.
Note! The DN211 I» accessed by T2E/T£N's READ
and WRITE instriJctinnE.
