Introduction
Overview
The purpose of this manual is to help users
develop safe and efficient procedures for
the installation, operation and maintenance
of the i-3 V2 I/O Modbus Controller.
The i-3 V2 I/O Controller is used to control
the operation of P1 Series with i-3 Control
Technology V2 Panel. The controller directs
SIPODs (Remotely Operated Contactors)
to switch ON/OFF. It also monitors the
contact status up to 42 branch circuits.
The i-3 V2 I/O Controller enables the P1
lighting panel to operate as a slave panel
to accept dry contact or wet digital inputs
and analog inputs or commands through
communications network by a Building
Automation System. It provides up to 20
two-wire dry or wet contact inputs and
two analog inputs which can be used to
control up to 42 outputs.

are capable of accepting up to 20 two-wire
dry or wet contact inputs. Two ten-pin
pluggable connectors will be used to
connect the input wires to external
devices. A six pin pluggable connector
(TB3) is used to connect the contacts
common to the board (if the six location
on the connector are not sufficient; the
commons may be jumped together
outside of the board and one common
wire can be brought into the board).
The recommended wire is 18 AWG
stranded copper.

Ribbon cable connector
There are two ribbon cable connectors
on the I/O Board that interface with the
data rails located on each side of the
P1 Series Lighting Panel. For safety
purposes, ribbon cables have a key feature
that prevents them from being connected
in the wrong orientation. A white mark
indicates the location of pin 1. In addition,
the pin 1 wire is black. The black wire must
be connected to pin 1 of the connector
where it lines up with the white mark.

Power supply
The power supply is mounted under the
I/O printed circuit board. It uses one of the
3-phase buses as the main power source.
The power supply provides power to the
controller and all its functions.
Fuse
The fuse protects the wire to the power
supply and I/O Board from short circuits.
This fuse is a 2 Amps class CC fuse rated
for 600Vac or less. Figure 2.7 shows
the fuse housing. To replace the fuse use
LittleFuse KLDR002 or equivalent.

Control Inputs/Outputs
Introduction
i-3 V2 I/O Controller provides a set of control
input terminals for wiring devices, such as
wall switches, photocells or occupancy
sensors. These terminals are located in the
input wiring section of the I/O printed
circuit board. There are two types of inputs
provided by these terminals:
• Switch inputs – The i-3 V2 I/O Contr
provides up to 20 input connections for
dry or wet (24 VDC) contacts (such as
wall switches, occupancy sensors, etc).
These contact inputs are capable of
acting either independently or in pairs
to turn ON and OFF. The controller can
accept up to 10 three-wire inputs or any
combination of two- and three-wire
inputs until its capacity is reached.
• Analog I/O – i-3 V2 I/O Contr
provides two analog input and two
analog output connections to control
0-10V dimming ballast.
There are two Analog Inputs (at TB6 on the
I/O Board) and two Analog Outputs (at TB5).
The Analog Inputs can be used to read any
0 to 10 Volt input value, and the Analog
Outputs can be used to drive out 0 to 10
volts ballast at a maximum of 100 mA each.
In a practical sense, this means that each
Analog Output can drive approximately 50
typical dimming ballasts (assuming each
ballast uses 2 mA – check your ballast
documentation for an actual determination).
Input / output connectors
oller

The Analog Inputs can be used in any
situation where digital inputs are used.
They are specified by using input numbers
33 and 34, but whether they are “ON” or
“OFF” is more complex. For each analog
input, registers 20 and 21 give the input
value in the range 0-4095. Registers 36
and 37 specify values to be compared
to the Analog Inputs and comparison
operations, to determine whether the
Analog Input is ON or OFF.
Register 36 is the Compare definition for
Analog Input 1 (input number 33), and
contains the comparison value in the
bottom 12 bits (least significant, bits
0-11, range 0-4095). The high-order bit
(bit 15) in that register stands for “equal”
comparison, bit 14 stands for “less,” and bit
13 stands for “greater.” These three bits may
be combined to make “less or equal” or
“greater or equal” or “always ON” (all three
bits on). If all three bits are off, then the
Analog Input is never ON. Register 37
controls the comparison operation for
Analog Input 2 (input number 34).
Controlling the Analog Outputs: Registers
38 and 39 give the actual, read only values
of the Analog Outputs 1 and 2. Like all
Analog values, they are a number in the
range 0 to 4095, corresponding to 0 to 10
Volts. (NOTE: The actual output may be
limited by the circuitry to approximately
9.2 Volts.)
Registers 22 and 23 are for specifying
Analog Output 1 Set value and Analog
Output 2 Set value. These Set values are
intended to be used to drive the Analog
Outputs. However, whether these Set
values are used by the Analog Outputs
depends on the Analog Output Feed
registers, 32 and 33.
Each Analog Output’s actual output value
can be tied to an Analog Input or to register
22 or 23, but not both. The Analog Output
Feed registers determine this tie-in. Register
32 (Analog Output 1 Feed) contains the
number of the Input to be tied to the
Analog Output. This number is from 0 to
44, where 0 is “no connection” and 1-20
are digital inputs, while numbers of 33 and
34 are analog inputs 1 and 2. These two
analog inputs act as a digital inputs based
on the Analog compare register values.
Numbers 35 and 36 specify the analog
inputs and the feed is through the direct
values of the analog inputs. Numbers 37
and 38 specify the analog inputs and the
feed is through the difference of the Max
Voltage (4095) and the direct values of
the inputs.
Numbers 39 and 40 do not represent an
actual input, but instead ties this Analog
Output to register 22 or 23, respectively.
Register 33 is for specifying the Analog
Output 2 Feed. Numbers 42 and 42 specify
the use of the analog gain table. Numbers
43 and 44 specify the use of the PID loop
function with values E0 and E1 respectively.

more information.
Input/output mapping
Setting input/output mapping can
be accomplished using Modbus
communication protocol or the
configuration software.
Any given input to the I/O Board may be
connected to one output or to an output
group or zone (which is more than one
output). Refer to Modbus Map table in

Chapter 5
Communication Protocol
Introduction
The i-3 V2 I/O Controller provides
Modbus as the standard communication
protocol. A personal computer or Building
Automation System may be connected to
i-3 V2 I/O Controller using a twisted pair
serial cable wired to RS-485 terminal
located in the communication interface
section of I/O Board.
The i-3 V2 I/O Controller will act as a
Modbus Slave using Modbus RTU or
Modbus TCP/IP (optional) slave protocol
when interfacing with Building
Automation System. Modbus master
devices connected to the controller
can access (read) the data, making
configuration changes and initiating
control actions.
Connecting the controller to a
Modbus System (PC or Building
Automation) system
A twisted pair serial cable is used to
connect the i-3 V2 I/O Controller to a
personal computer or Building Automation
System. RS-485 to RS- 232 conversion
cable is required to connect to a personal
computer. This cable is connected to the
RS-485 terminal which is located in
the I/O Board communication interface
section as shown in Figure 5.1.
The RS-485 terminal is accessible through
Communication Interface Door without
removing the panel deadfront. See Figure
3.1 on page 8.
Configuring i-3 V2 I/O Controller
There are two methods of configuring
i-3 V2 I/O Controller: using The Panel
Configurator Software or Modbus
communications.
1. Using the i-3 V2 I/O Configurator
Software
Refer to “i-3 V2 I/O Configurator
Software Tool” section for instructions
on how to download this program from
our Web site.
2. Using Modbus Communication
Assigning a Modbus address
By default, i-3 V2 I/O Controller device
address is assigned as 126. If multiple
i-3 V2 I/O Controllers or other Modbus
devices are present on the same line,
each device must be assigned a unique
device address.
The Modbus address is programmed
with rotary switches located on the
electronic board.
See Appendix A – Modbus Address
Table for rotary switch settings.
Changing input types
To change input types, follow the steps:
1. Use either function code 6, preset
single register or 16: preset multiple
registers.
2. The register address for input types
ranges from 1792 (for input terminal 1)
to 1811 (for input terminal 20).
3. Assign the desired input type value,
which can be found in the Modbus Map
Table on page 10. For example, input
type “3” is digital input maintain
normally ON switch (2-wire).
RS-485
Terminal
Figure 5.1
i-3 I/O Controller Communication Interface

Chapter 5
Communication Protocols
Creating output groups
An output group consists of a set of
SIPODs. To create an output group, follow
these steps:
1. Use either function code 6: preset single
register or 16: preset multiple registers.
2. The register addresses for output group
definition ranges from 256 (for output
group definition 1) to 380 (for output
group definition 125).
3. Assign the register value to create as
many output groups as desired. Note:
Each register is made up of two bytes:
the first byte represents the output
group number and the second byte is
the SIPOD number. For example, if the
register contains 0x0402, then the
output group is 4 (0-relative numbering)
and the SIPOD is 2. There can be
duplicate output groups and/or SIPODs
within the table. This means an output
group can contain more than one SIPOD,
and a SIPOD can be in more than one
output group.
Mapping input-to-output
By default, the factory assembled i-3
V2 Controller input-to-output mapping
is not set. Input-to-Output mapping can
be redefined as desired to meet the project
specification. To map input to output,
follow these steps:
1. Use either function code 6: preset single
register or 16: preset multiple registers.
2. Register address for input-to-output map
starts from 2048 for input terminal 1 to
2067 for input terminal 32.
3. Assign the register value for the desired
input maps. Note: Each entry (register)
in the table has two parts: a high order
byte that is either 0 (for an output
mapping) or 0x80 (for an output group
mapping), and a low-order byte that
specifies either an output (SIPOD)
number or an output group number.
The table is indexed by input number.
For example, if the fifth entry (register)
in the table is 0x0001, then input
number 5 is mapped to SIPOD 1. If the
tenth entry (register) is 0x8004, then
input number 10 is mapped to output
number 4.
Refer to Modbus Map table on page 14
for additional information.
Other configuration functions
Other functions, such as reading SIPOD
status, reading input status, setting up
SIPOD parameter, etc., are listed in the
Modbus Map table on page 14.

SIPOD Status
The first (high-order) byte of the SIPOD
Status Word contains:
+---------------------------------------------------+
| P | R | D | O | S | S | | |
| O | S | E | V | P | P | | || Control byte
| D | T | F | F | 1 | 2 | | |
+--------------------------------------------------+
SIPOD – SIPOD initiated message – set
when the message originates in the SIPOD
rather than the I/O Board.
RST – Reset flag – sent from the SIPOD
to the I/O Board in the first message after
a system reset.
DEF/FIN – Default/Finishing flag
This flag has two meanings – one if the
message originates in the SIPOD, and
another if the message originates in the
I/O Board. In a SIPOD message, it means (if
on) that the default values of parameters
have not yet been set – in particular, no
“SetParameter” message has been received
from the IO Board since the most recent
SIPOD reset.
In messages originating in the I/O Board,
the FIN flag indicates that no more data
will be sent to the SIPOD. It also indicates
that no more data will be accepted. No
data may be sent in a packet which has the
FIN flag set. The FIN flag is not currently
used, and is intended for situations where
there are multiple packets sent from the I/O
Board – not for single messages.
OVF – Command overflow flag
This flag indicates that at least one
command previously sent to the SIPOD was
ignored because there was no room
in the task queue. This means that
commands are being sent too quickly
for the SIPOD to handle them.
SP1 – Status of Pole 1
This is equal to 1 if the first pole is closed.
SP2 – Status of Pole 2 (for 2-pole PODs)
This is equal to q if the second pole is
closed.
The second (low-order) byte of the
SIPOD Status Word contains:
• Bit 7 (left-most bit) – Open/Closed flag
ON = Closed;
OFF = Open.
• Bit 6 – OIP – Open in process flag
• Bit 5 – CIP – Close in process flag
• Bit 4 – FAIL – Failure flag (failed to open
close)
or
•
Bit 3 – NAK flag (a previous message
was g
• Bit 2 – MxO – Maximum Opens per
minute
• Bit 1 – MxC – Maximum Closes per
minute
• Bit 0 – SQE – Sequence Error flag (a
pr
The Open/Closed flag is set based on the
Auxiliary Detector in the SIPOD. This is a
contact switch that mimics the operation
of the power contacts.
Note that the FAIL, NAK, and SQE flags
are sent only once, and then cleared. All
three of these flags mean that there was
a problem since the last time a status was
sent to the I/O Board – not necessarily
related to the previous message from the
I/O Board. For example, if the I/O Board
requests an Open, then a Close, then sends
GetStatus and the status contains
a FAIL flag, then either the Open or the
Close failed (or both), but the I/O Board
cannot determine which operation failed.
Timed inputs
Each register represents a 16-bit signed
value (-32766 to +32767), which gives
the number of minutes to time an input
when it is switched ON. The default is 0,
meaning “do not time this input”. The
maximum value is 32767 (about
22.75 days).
After this time, the input will be turned
“OFF” logically – that is, the switch may
be physically in the ON position, but any
SIPODs mapped to it will be turned off.
arbled)
reached
reached
evious message was out-of sequence)
NOTE: There is a built-in delay of up to
one minute, so setting this time to 1 will
result in the input turning “OFF” after a
minimum of one minute and maximum
of two minutes.
Putting 0 in this register means there is no
timing: that is, the switch is ON indefinitely
until operated OFF.
Timed SIPOD overrides
Each register represents a 16-bit signed
value (-32766 to +32767), which gives
the number of minutes to time a SIPOD
override. The default is 0, meaning “ there
is no override.” The maximum time is +
or - 32767 (about 22.75 days). A positive
value will turn the SIPOD ON for that
amount of time. A negative value means
the SIPOD will be turned OFF for that
amount of time.
For example, a value of +15 will turn the
SIPOD ON for 15 minutes. A value of -20
will turn the SIPOD OFF for 20 minutes. So
the absolute value of the register indicates
the time, and the sign of the register indicates ON or OFF.
After this time, the override will be
disabled logically. The SIPOD will return
to whatever state (ON/OFF) it would be
in if the override had not happened.
Putting 0 in this register means the
override is disabled. In other words,
overrides are always time-limited.
If the registers are read, they return the
value of the time left in the override and
indicate by being negative or positive
whether the SIPOD is turned OFF or ON.
IOB control word
As a safety precaution, there is a password
value required in the high-order byte of the
IOB Control Word to enable use of
any of the control bits. This is to prevent
accidental activation of the control bits
it is not meant to prevent unauthorized
access. The password value is 0xA0
(hexadecimal A0, decimal 160).
Note that the IOB Control Word always
returns 0 (0x0000) when read.
Bit 0 -- if ON, clears all statistics of the
IO Board

Chapter 5
Communication Protocols
Bit 1 -- if ON, run the IOB Diagnostics
routine
Bit 2 -- if ON, reset the IO Board
Bit 3 -- if ON, restore defaults to the
parameters of the IO Board (but not the
Modbus device address) as well as the
Date and Time.
Bit 4 -- if ON, restore defaults to the
Output Groups Table (i.e., no output
groups defined) and the Input-Output
Mapping Table (i.e., 1-to-1 mapping of
32 digital inputs to the first 32 outputs)
Bit 5 -- If ON, restore defaults to the Input
Types Table (i.e., all digital input types set
to 0) and to Inputs Force (i.e., turn off
all forcing). In addition, the states of all
inputs are initialized.
Bit 6 -- If ON, indicates the IO Board should
go into Program Upgrade mode – stopping
all activity except for receiving memory
updates (allows reading/writing of the IOB
Memory Access Table and writing register
115 – the IOB Control Word)
Bit 7 -- If ON, cancels the Program Upgrade
mode (IO Board goes back into normal
mode – all normal functions are enabled)
To activate one or more of these bits, you
must add the password value and write the
word. For example, if you wish to reset
the IO Board, you must write 0xA004
(hexadecimal A004).
Input forcing
Using a combination of the Inputs On/Off
(registers 18 and 19) and the Inputs Force
(registers 16 and 17), the user can force
the state of individual and multiple inputs
to be either On or Off. The Force All
On/Off switch on the IO Board still has
the highest priority of action, but Input
Forcing is second to that switch when it
comes to priority of action.
The state of an input (On or Off) can be
read or written in registers 18 and 19.
However, writing to an input state has
no effect unless the corresponding bit in
registers 16 or 17 is set to 1. Therefore,
registers 16 and 17 act as a mask of
registers that are being forced, and
registers 18 and 19 act as forced states or
actual states of inputs, depending on the
mask registers.
Note that when an input is being forced,
the actual state of the input has no effect
whatsoever, until the forcing is turned
OFF for that input. This may lead to some
confusion, i.e., someone trying to toggle a
light switch and seeing nothing happen to
the lights.

To obtain this software, please contact
Siemens at 800-427-2256. Software will
be available for download online.
Input Logics
Registers 3584 through 3603 specify an
optional logic operation for each Input.
Each register contains a 0 (“OR”), 1
(“AND”), 2 (“NAND”), or 3 (“XOR”) in the
first byte and an input number (1-20 for
digital inputs or 33 analog input 1 or 34
for analog input 3) in the second byte. A
value of 0 in a register means that there is
no Logic operation to be applied. A Logic
operation allows the user to relate two
different inputs to a POD with an AND,
OR, NAND, or XOR logical connection.
NOTE: A special situation can occur when
two inputs are linked to each other and
one has an “OR” operation and the other
has an “AND” operation. This could lead to
a race condition, causing the SIPODs to
clatter as they try to satisfy both conditions.
In order to prevent this, the software
will automatically give both Inputs the
same Logic operation whenever it detects
the condition. In the case or an XOR or a
NAND, just the opposite is true, in that if
both inputs point to each other and have
XOR or both have NAND, this creates a
race condition, so the system removes
the Logic operation
Communication loss
Placing a value in register 781 indicates how
long (in minutes) the I/O board should wait
to determine if communication is lost. The
15th bit in register 781 specifies what to do
when communication is lost. If the 15th bit
is set, all SIPODs will be turned ON. If the
15th bit is not set, all SIPODs will be turned
OFF. The user enters the value in the
remaining 15 bits. The maximum value is
10000 minutes, the minimum value is 1
minute. If the value is FFFF, the I/O board
does not check for communication loss.
SIPOD Delay
The user can specify the time (in
milliseconds) for SIPODs to be ON for
the commands SIPOD_CLOSE and
SIPOD_OPEN. The default its 0. The
maximum is 65536.

Analog Gain
If the analog feedback data from the lighting sensor falls between 0 and threshold
setting 1, Programmable Ramp sets the
analog output to level 1.
If the analog input data from the lighting
sensor falls between threshold setting 1
and threshold setting 2, Programmable
Ramp sets the analog output to level 2.
If the analog input data from the lighting
sensor falls between threshold setting 2
and threshold setting 3, Programmable
Ramp sets the analog output to level
3, etc.
