Overview
Omron's DeviceNet module for NT31 and NT631 operator interfaces
provides open communications with DeviceNet masters (scanners)
from any manufacturer.
Easy
Typical of Omron DeviceNet solutions, the NT-DRT21 DeviceNet
module makes implementing HMI communications almost automatic.
Assign a DeviceNet network node number to the NT operator interface
and Omron's DeviceNet master automatically enrolls the unit,
establishing communications without further configuration. Up to 32
input and 32 output words can be mapped automatically and are
continuously scanned by the DeviceNet master. An additional 120
words of data can be accessed within the HMI using Explicit
Messaging on the DeviceNet network.
Convenient
Reduce wiring effort and expense by placing your HMI onto the
existing DeviceNet network. There is no need to run additional serial
cables for operator interface communications. The operator interface
can reside on the I/O network up to 500 meters away from the
DeviceNet master.
Open communication standard
The NT-DRT21 is compatible with third-party DeviceNet masters, so
the NT31/631 units can be placed on any system, allowing a facility to
standardize on the Omron NT31/631 platform. Programmed NT31/631
units can be used with masters from different vendors without
changing the screen program.
Upgrade operating system
The NT31/631 units are shipped with an operating
system (OS) that supports communication. This OS
must be replaced with one that supports the NT-DRT21
interface module. Simply connect to Port A on the
NT31/631 with the C200H-CN229-EU communication
cable, plug into your PC serial port, and use the NT-
Series System Installer (included with NTST) to
download the DeviceNet OS.
Connect
The NT-DRT21 module mounts to the expansion
interface connector on the back of the NT31/631 unit, as
illustrated. Connect the NT-DRT21 to the DeviceNet
network 5-wire cabling.
Set communication parameters
The system menu for the NT31/631 DeviceNet OS contains the
following parameters:
• Communication Speed (Baud Rate): 125, 250, or 500 kbps
• DeviceNet Node Number: 0 to 63
• Strobe ON Time: 30 to 100ms
• Output Area Leading Address: Memory Link word 0000 to 9999
• Output Area Size: 5 to 32 words
• Input Area Leading Address: Memory Link word 0000 to 9999
• Input Area Size: 5 to 32 words
