1.4.2 Optional Network Interface With Isolated Digital Pulse Input (Di3)
The D-100 Display can be provided with an digital pulse input for totalizing pulse outputs
from external devices such as water or gas meters. Pulses are accumulated in an internal
register, and the totalized value is available on the network. This register can be zeroed via
the network. The maximum register total is 9,999,999. The register will rollover to zero
when this value is exceeded.
If the digital pulse input option was ordered at the same time the display was ordered,
it will arrive fully congured and ready to use. If it was ordered after the display was
delivered and is being installed as a eld upgrade, it may be necessary to congure the
pulse input. The information is required to congure the input provided below and on the
following pages:
The input pulse must meet the following criteria:
1. Frequency input range, 50 Hz maximum
2. 10 millisecond minimum pulse duration
Input Pulse Denition:
In order to congure the communications card digital pulse input, you must rst
determine which type of pulse your meter produces. The allowable types of input
pulses are described on the following pages. Based on the type of pulse, set the selector
switch (S1) on the communications circuit board (Fig. 1) to the correct setting.

Powered Pulse:
This type of output refers to a pulse which has an associated voltage with it (see Fig. 2).
Set the selector switch, S1 to Pwrd Pulse. The allowable voltage range is 5-24 VDC. The
input impedance is set at the factory to be 11 KOHM via the impedance selector jumper
(J1, see Fig. 1). A lower impedance, 3 KOHM can be selected if required by the instrument
providing the pulse output. Consult the instrument manufacturer or ONICON if you are
uncertain as to the proper jumper selection.

1.5 NETWORK ADDRESSING
The display contains two microprocessors, the D-100 board processor and the Echelon
TP/FT-10F transceiver with its Neuron processor. The TP/FT-10F transceiver is located on the
LON board. The two processors communicate with each other using a serial channel. This serial
channel device address is xed at 017 and cannot be changed.
1.5.1 LonWorks Network Addressing
Every Neuron processor has a unique 48 bit address known as the Neuron ID. This address
is generally used as the Node ID. It is combined with the Domain ID and Subnet ID to form
the device address. In most installations, the device address is created dynamically by the
network.
1.6 COMMISSIONING THE FLOW DISPLAY
Pressing the Service Pin on the LON board (see Appendix 2) generates a service pin message on
the network. The message contains the Neuron ID and the standard program identier (SPID).
The network conguration tool then maps the D-100 Neuron ID into the domain/subnet/node ID
addressing scheme for the network, creating the device address.
1.6.1 Service Pin LED States
The yellow service pin LED indicates the status of the Lon Talk network connection.
• LED blinking at ½ Hz rate indicates that the meter is in an decommissioned state.
• LED off indicates that the meter is commissioned and operating normally.
1.7 LONWORKS XIF FILES
Each D-100-LON Flow Display is shipped with a diskette or CD containing the XIF le. It also
contains the Neuron executable le in various formats and documentation describing the
network variables in detail.
1.7.1 Output Network Variables
The D-100-LON Flow Display transmits data to the network using Standard Network
Variable Types (SNVTs). Volume ow rate, and volume total are provided in oating point
format.
Display operating mode and mode status information is provided in ASCII character format.
The oating point output network variables are described in the table on the next page.
Column 1 contains a brief description of the network variables. Column 2 contains the
network variable names. Column 3 contains the Lon SNVTs used for each variable. Column
4 contains the engineering units, and column 5 contains the valid range for each variable.

1.7.5 Resetting Totals via the Network
Totals are held in non-volatile memory within the display. Each total (ow or auxiliary
input) has a corresponding output variable that transmits the information from the display
to the network. There are two ways to remotely reset totals in the display. This can be
done using individual input variables to command the display to reset specic totals or it
can be done using the nviRequest variable. Using nviRequest allows you to reset each total
individually or all totals simultaneously with one command. See sections 1.7.3 and 1.7.4.1
for specic instructions on how to reset totals.

1.7.6 Rollover of Totals
The totals stored in the ow display memory will roll over to zero when the maximum
count is exceeded. When this occurs, the network totals will also roll over to zero. The
point at which the rollover occurs is a function of the displayed engineering units and
multipliers programmed into the display.
The examples below show the rollover point in the engineering units transmitted by the
network variable (SNVT) for common totals shown on the D-100 Flow Display.

SECTION 2.0: NETWORK TROUBLESHOOTING TIPS
2.1 TROUBLESHOOTING
NOTE: Also refer to the COMMISSIONING GUIDE located on the preceding pages.
REPORTED PROBLEM POSSIBLE SOLUTIONS
For turbine meters -
No Flow Signal (while
hydronic system is
active)
• Verify 24 VDC supply voltage to the ow meter.
• For insertion meters, verify the ow meter is correctly inserted
into the pipe (using depth gage).
• For insertion meters, verify that the ow meter electronics
enclosure is parallel with the pipe.
• Verify correct wiring to the ow meter (see wiring diagram).
• For turbine meters, check turbine(s) for clogging due to debris.
• If none of the above, check hydronic system to ensure that ow is
really present in the line.
• NOTE: Flow meter function cannot be veried by blowing on the
turbine(s). The sensing system requires a conductive liquid to
operate. You can test it by swirling it around in a bucket of water
and looking for the ow indicator LED to ash at the D-100.
Displayed ow rate too high
or too low
• Verify pipe size. Contact ONICON if pipe size is different from
calibration tag.
• For insertion meters, verify that meter is inserted correctly into the
pipe (using depth gage).
• For insertion meters, verify that the ow meter electronics
enclosure is parallel with the pipe.
• For dual turbine meters, conrm that both turbines produce
pulses.
• For turbine meters, check turbine(s) for debris.
• Verify supply voltages (to display and ow meter).
Device is not communicating
with the Lon Talk network.
• What is the state of the service pin LED?
• Is it ashing? A ashing service pin LED indicates that the Lon
module has not been commissioned.
• Is it off? A service pin LED that is off indicates that the Lon
module is commissioned and operating normally.
Communications with the
Lon Talk network is inter-
mittent.
• Is the network properly terminated? The Lon TP/FT bus can be
terminated in 2 different ways.
• A single RC lter can installed at any point on a free topology
network. A dual termination scheme is used with 2 RC lters
installed at the ends of bus networks. Refer to the drawings below
for details.
• What type of cable is used to wire the network? TP/FT networks
should only use twisted shielded pair cable. (Belden 85102 or
equiv.)

INTEGER FORMAT OUTPUT NETWORK VARIABLES
Integer format output variables are limited to 2 bytes of data. For this reason, the maximum number that
can be transmitted in this format is 65,535. Values for both rate and total data will often exceed this limit.
Rate Variables
The integer output network variables for volume rate are described in the table below. Column 1 contains
a brief description of the network variables. Column 2 contains the network variable names. Column 3
contains the Lon SNVTs used for each variable. Column 4 contains the engineering units and column 5,
the valid range for each variable.

*Energy rate nvoEnrRateKWi SNVT_power_kilo KWatts 0 to 65535
* These network variables are present but not used by the standard D-100.
Total Variables
The integer output network variables for total are described in the table below. Column 1 contains a brief description
of the network variables. Column 2 contains the network variable names. Column 3 contains the Lon SNVTs used
for each variable. Column 4 contains the engineering units and column 5, the valid range for each variable.
Please note that while the oating point variable for FLOW total is transmitted in liters, the integer
network variable for FLOW total is transmitted in kLiters. This is done to increase the maximum total
that can be transmitted via the integer variable. Total(s) must be reset before the accumulated value
exceeds 6553.5 kliters using nviResetVol1a and/or nviResetVol2a. If this is not done, nvoVol1KLi and/or
nvoVol2KLi will over range and continue to indicate 6,553.5 kliters (1,731,252 gallons) until the D-100’s
internal total rolls over to zero.
A separate integer SNVT is also available to transmit ow totals in liters. This variable is only used in
special small pipe applications as the maximum total it can accumulate is only 65,535 liters (17,312
gallons) before it must be reset.
