H8163-CB INSTALLATION GUIDE
OPERATION
The H8163-CB energy meter communication board is an optional eld-installable
board for the H8163 energy meter that allows Modbus RTU communication. The
H8163-CB also enables the energy meter to provide true kW & kVAR demand
information.
The easy-to-install H8163-CB provides a simple, cost-eective way to network the
H8163 energy meter on a Modbus network.

H8163-CB INSTALLATION GUIDE
CONFIGURATION
This section describes the communications settings you must make to the H8163-CB.
When daisy-chaining Modbus devices, follow these guidelines:
• Connect up to 63 H8163-CB devices on a single daisy chain.
• Each H8163-CB device on the daisy chain must have a unique address.
Before connecting the H8163-CB to the RS-485 communication wires,
set the address according to directions on this page.
• Set the wiring type, baud rate, and parity according to directions in
“Selecting Wiring Type, Baud Rate, and Parity Settings” on this page. The
settings for each H8163-CB must match the other devices on its daisy
chain.
• For RS-485 cables, use shielded, twisted-pair wire (Belden Cable 1120A or
equivalent).
• Terminate the last device on the daisy chain to ensure reliable
communication per the RS-485 standard (120 Ω nominal impedence).
Selecting The Network Address DIP Switches
Use the network address DIP switches to select the network address. Each H8163-CB
on a daisy chain must have a unique network address (from 1 to 63). Devices with the
same address as another on the chain will be unable to communicate.
Always set the address before you install the H8163-CB in the energy meter and
before you connect the energy meter to the daisy chain.
Each of the six DIP switches has a unique address value. The Modbus Addressing
section on page 6 lists DIP switch positions for specic addresses.

Daisy Chain Maximum Distances
The maximum number of devices allowed on a single daisy chain is determined by
combining the baud rate, the length of the daisy chain, and the types of RS-485
devices (2-wire/4-wire) on the chain. The RS-485 interface will support daisy chains
that fall within the specications shown below.

Wiring the Connector
1. Remove the connector from the RS-485 communication terminals of the H8163-
CB.
2. Wire the communications connector as shown on page 4 (2-wire or 4-wire
communication). The wire type setting in the communication DIP switch must
match this wiring type.
3. Use a small, at-blade screwdriver
to tighten the connector screws.
Apply the correct torque: 0.37-0.44
ft·lb (0.5-0.6 N·m).
4. Replace the connector on the RS-485 communication terminals of the H8163-CB.
5. If the H8163-CB is the last device in a daisy chain, terminate it to ensure reliable
communication per the RS-485 standard (120 Ω nominal impedence).

H8163-CB INSTALLATION GUIDE
INSTALLING THE H8163-CB IN THE
ENERGY METER
Complete the Communications Setup and Wiring instructions
before installing the board inside the meter.
The H8163-CB is designed as a plug-and-play accessory for the H8163 energy meter.
Follow these instructions to install the H8163-CB into the energy meter.
1. Turn o all power to the energy meter and the equipment in which it is installed.
a. Remove the voltage terminal from the energy meter and all fuses.
b. Always use a properly rated voltage sensing device to conrm that power
is o.
2. To discharge static, follow the instructions that come with your anti-static or
grounding strap. We recommend using an anti-static or grounding strap until the
installation is complete.
3. Slide the H8163-CB into the slot in the H8163 housing. The sides of the H8163-
CB slide down into the channels on either side of the energy meter. When the
male connection to the H8163 board clicks into place, the H8163-CB is properly
installed.
4. Insert the communication terminal onto the RS-485 communication terminals.
5. If the demand subinterval feature is used, wire into the end of demand subinterval
terminal.
6. Replace the voltage terminal into the energy meter.

If communications are not working properly, rst check that the board is properly
seated in its slot in the energy meter, and that the connector has clicked into place in
the connection slot on the meter.
There are ve LEDs that indicate various types of communication.
During normal operation, all ve LEDs will blink regularly. When an error occurs, the
abnormal LED will help determine where that error is.

NOTES
Integer format registers represent the data as 16-bit integer values. Float format
registers represent the same data, as 32-bit oating point values.
For measured data, the oat format registers are recommended. The integer format
registers are dicult to use for the measured data, as a multiplier must be employed
for each to calculate the correct value. Most of the multipliers change, depending on
the CT size. Reading the oat format registers avoids the need to use multipliers.
Modbus Block Reads
There is no maximum block size restriction, as with the 80xx Series power meters, as
the entire Modbus response is fully buered. However, the total number of registers
requested may not exceed 125, as the Modbus protocol only allows up to 256 bytes.
125 registers * 2 bytes per register + 5 bytes overhead = 255 bytes.
Demand Computation, Internal Algorithm
The meter computes average kW/kVAR, by accumulating every kW/kVAR reading
and keeping a count of the number of kW/kVAR readings accumulated. This occurs
every 200 msec (5 Hz). The accumulated value, divided by the number of kW/kVAR
readings, is the present sub-interval demand (kW/kVAR), which is read at registers 25
(kW) and 28 (kVAR).
A sub-interval may be terminated in three ways.
1. If a write to the command register has bit #0 set.
2. If the hardware signal (interval reset) is detected.
3. If the sub-interval length (register 36) is set to a nonzero level and the count of the
number of kW readings equals or exceeds the nonzero sub-interval length.
Although there are three ways to end a sub-interval, it is assumed that applications
will use only one of them.
The maximum legal sub-interval length is 65535 readings, which corresponds to 3
hours, 38 minutes, 27.2 seconds. When the 65535th reading is taken, the sub-interval
reading counter overows. The H8163-CB detects this and ends the sub-interval. The
next sub-interval begins on the next reading. In normal operation, it is expected that
a sub-interval will not last longer than 1 hour.
When a sub-interval ends, the average kW/kVAR during that sub-interval (the
accumulated kW/kVAR readings divided by the number of readings) is added to a
six-value FIFO (rst in, rst out) that stores the six most recent sub-intervals. The kW/
kVAR accumulator and count of kW/kVAR readings are cleared to zero to begin a new
sub-interval. The count of sub-intervals (register 34) is incremented. The present
demand is recomputed by averaging the rst N elements of the FIFO, where N is
the value in register 37. If the new present demand is higher than the stored peak
demand, then the peak demand is updated to the new present demand.
Miscellaneous
Some registers list a model sux. These registers apply only to those models.
Registers that are not available for the particular model will read “0xFFFF” for integer
points and “NaN” for oating point registers.
The kW accumulator is reset by writing to the command register with bit #1 set. This
clears the kWh accumulator to zero. Any writes to the kWh points are ignored.
Floating Point Registers
All oating point values are compatible with the “32 bit IEEE real” format. All oating
point variables are read-only. All read/write points must be written to their integer
registers.
