Vendor Association, Inc.
About Hardy Manuals Every Hardy Installation and Operation
manual is organized into easily referenced chapters, that are almost always
the same:
• Chapter One - Provides an introduction and an Overview of the instrument and its capabilities.
1-1
HI 200DNWM MANUAL
• Chapter Two - Provides a complete
list of Specifications.
• Chapter Three - Contains information needed to Install the HI
200DNWM weight module.
• Chapter Four - Provides complete
hardware Configuration instructions for setting dip switches and
jumpers.
• Chapter Five - Pertains to the firmware Setup and preparation procedures to calibrate and operate the
module.
• Chapter Six - Provides Calibration
instructions.
• Chapter Seven - Pertains to the
Operation of the HI 200DNWM
weight module.
• Chapter Eight - Pertains to the
Troubleshooting procedures to
repair the module.
Description The Hardy Instruments HI 200DNWM is
a small weigh module that communicates
Net and Gross weights to other devices
connected to a DeviceNet™ Network.
The weigh module supports Hardy’s
®
calibration and has four levels of
C2
WAVERSAVER®. The weigh module
consists of a printed circuit card with
standoffs (for mounting in an enclosure)
or rails for DIN rail mounting. The weigh
module outputs (produces) Gross, Net
and Tare weights and inputs (consumes)
Zero and Tare commands via
DeviceNet™. Configuration includes:

2. Averages (1-255)

4. Calibration Type (C2® or Hard

Read Only
5. Span Weight
6. Set Point Values
a. Mode
b. Preact
c. Deadband
NOTE: WAVERSAVER® and C2® are registered trade-
marks of Hardy Instruments, Inc.
Configuration data is stored in an
EEprom. I/O slave messaging is polled.
The weight module supports two TTL
levels out to relays for use as set points.
A bit is supplied when the set point is
reached.
NOTE: Hardy Instruments does not supply the set point
module.
WAVERSAVER® Typically, mechanical noise is present in
forces larger than the weight forces trying to be detected. The HI 200DNWM
weigh module is fitted with WAVER-
®
SAVER
technology which eliminates
the effects of vibratory forces present in
all industrial weight control and measurement applications. By eliminating
the factor of vibratory forces the controller is capable of identifying the actual
weight data. WAVERSAVER
®
enables
1-3
HI 200DNWM MANUAL
the weigh module to distinguish between
actual weight data and mechanical noise,
both of which are typically transferred to
the weight controller by the load cell sig-
nal. WAVERSAVER® can be configured from devicenet controller to ignore
noise with frequencies as low as 0.5 Hz.
One of three other additional cut off frequencies may be selected to provide a
faster instrument response time. The
default factory configuration is 1.0 Hz
vibration frequency immunity.
C2® Calibration C2® Second Generation Calibration
enables a scale system to be calibrated
electronically without using certified test
weights which equals the systems load
capacity. All Hardy Instruments C2®
certified load sensors contain digital
information detailing its unique perfor-
mance characteristic s. C2® Calibration is
performed over the network or by simply
pushing “THE BUTTON”and hold until
the module status LED (DS2) goes out.
The Button With one push of “THE BUTTON” the
HI 200DNWM automatically electronically calibrates the weighing system with
®
certified load sensors, making the
C2
system ready for use. This saves system
start up time costs and aggravations.
What is DeviceNet
®
? The DeviceNet network is an open, glo-
bal industry-standard communication
network designed to provide an interface
1-4
CHAPTER 1 - OVERVIEW
through a single cable from a programmable controller directly to smart
devices such as sensors, push buttons,
motor starters, simple operator interfaces, drives and weigh modules. You no
longer have to hard-wire each device to
an I/O module or I/O block. Because
you use significantly less wire, you
spend far less time and money on wiring
and installation time. The network also
provides access to the intelligence
present in the devices for superior diagnostics and troubleshooting to help
increase system up time. The DeviceNet
network lets you monitor your plant-
Physical Layer
(Network Topology)
floor devices from a central location and
reconfigure them as your needs change
or service them as required. You can, for
example, configure the weigh module for
different applications. The DeviceNet
network's capabilities help ease integration, and reduce installation and wiring
costs. (See Fig. 1-1)
• Trunk Line (thick or thin cable can
be used)
• 120 ohm terminator at each end.
• Drop lines can extend to a maximum
length of 20’ feet.
• Drops may be daisy chained to multi-
ple nodes.

• Zero length drops allow direct connection of nodes to the trunk.
• Multiple power supplies can be used
