The choice between RS232 and RS485 can be made with PLC programming
software (see p. 15). RS232 is the default protocol.
Modbus communication capabilities are described in more detail later in this manual
(see p. 35).
Note: The Modbus port connector and the Ethernet connectors at the top of the
module are female RJ45 connectors with a similar look. Do not attempt to make an
Ethernet connection through a Modbus connector.
The 171 CBB 970 30 processor requires 19.2 to 42.5 VDC of power to the unit from
an external safety extra-low voltage (SELV) power source. The 3-pin power
connector is located on the bottom left of the module. The connector’s pin

Processor Overview
Memory Characteristics
Introduction
The Momentum 171 CBB 970 30 processor is equipped with internal memory and
Flash RAM.
Internal Memory
Internal memory comprises user memory and state RAM.
User memory contains the control logic program and the system overhead
(processor adapter configuration, I/O mapping, checksum, system diagnostics,
etc.).
State RAM is the area in memory where all the input and output references for
program and control operations are defined and returned.
You can change the processor’s internal memory allocation using the PLC Memory
Partition feature that is part of your panel software.
Flash RAM
Flash RAM contains the executive firmware, which is the operating system for the
PLC. It also contains a firmware kernel, a small portion of memory that recognizes
acceptable executive firmware packages and allows them to be downloaded to the
processor. The firmware kernel cannot be changed.
You can store a copy of the application program and the state RAM values in Flash
RAM.
When the Momentum 171 CBB 970 30 has successfully established communication
with other devices, we recommend that you stop the processor and save the
application program to Flash. This manual describes the procedures for saving-toFlash with both Concept (see p. 67) and ProWORX 32 (see p. 89).
This procedure saves the processor’s ARP cache, enabling you to rapidly restore
communication if power is lost or removed. It is also useful when a new or substitute
device is installed on the network or when the IP address of a network device is
changed.

Noise Immunity
Considerations
If the processor is operating in a noisy environment, you may insert a jumper
between the – VDC and
VDC
+ 24
pins in your power cable:
VDC
–
If you are using a grounded power supply, the jumper is not required.
If any other devices in your system are connected to the same power supply as the
171 CBB 9730 processor, your power supply connection must not affect any of
these other devices.
You must maintain a voltage of less than 44 VDC between the – VDC and
pins.
Note: Your electrical installation must meet local or nationally applicable safety
standards and regulations.
Power Cable
Recommendations
The PE ground must be capable of supporting 30 A of current for 2 minutes with no
more than 50 mΩ of resistance. The recommended wire size is 3.2 to 0.87 mm2
(12 to 18 AWG). (The maximum wire size must not be exceeded even if your wire
contains the –VDC-to-PE jumper.)
The maximum allowable length of the cable at 18 AWG is 2 m.
Note: A single-point connection between the PE and –VDC is recommended in a
+24 VDC power wiring system.

Lithium Battery
Introduction
Due to the characteristics of the lithium battery, the operating life cannot be
accurately determined. Major factors reducing battery capacity are:
z
z
z
z
storage temperature
operating temperature
time in storage
battery use
If battery backup is required, Schneider Electric recommends configuring the
battery-low coil in the PLC configuration, a setting that allows monitoring of the
battery capacity level. A battery low condition exists when the configured battery low
coil goes to 1.
The Momentum 171 CBB 970 30 processor contains a factory-installed lithium coin
cell battery. It is shipped with the real-time clock disabled, and the SRAM is not
battery backed. When the processor is powered on for the first time, it runs on the
battery and the battery-backed SRAM is enabled.
You can set the time of day using either Concept (see p. 53) or ProWORX 32
(see p. 87). If you do not set the clock, it starts running with a factory-set date of
1 June 2006 at first power-up.

Battery-low
Threshold Level
31007547 1/2007
The back-up life of the lithium battery when it is supporting the processor’s
memory while the processor is powered off is typically 3 years after the real-time
clock is set
The back-up life of the lithium battery when the processor is powered up and
running is typically 5 years
A circuit monitors the voltage of the lithium battery. you can set a battery monitoring
coil in the configuration with Concept (see p. 50) or ProWORX 32 (see p. 87). When
the battery voltage gets weak, this battery-low coil turns on—i.e., its value is 1. When
the battery coil turns on, you have 30 days to replace the battery.

The Ethernet Switch
Introduction
The Ethernet switch built into the Momentum 171 CBB 970 30 processor allows you
to connect the processor to an Ethernet network. Ethernet connectivity gives you:
z
z
z
z
z
Key Features
high-speed I/O servicing
high-speed data transfer
remote programming
worldwide connectivity via the Internet
interfaces with a wide array of Transparent Ready devices
The Ethernet switch has four 10/100BASE -T ports that can operate independently
at 100 Mb/s full-duplex or half-duplex, or at 10 Mb/s full-duplex or half-duplex. It
supports switched Ethernet networks in accordance with IEEE standard 802.3 or
802.3u using copper technology.
The switch supports:
auto-negotiation The switch automatically negotiates speed (10BASE-T or
100BASE-T) and full- or half-duplex mode. Auto-negotiation is managed
independently on each of the four switch ports.
auto-polarity The switch detects and compensates for an incorrectly wired cable,
i.e., cable where the RX+ and RX- signal inputs need to be swapped. Autopolarity is managed independently on each of the four switch ports.
auto-MDI/MDI/X The switch auto-switches the transmit (TX) and receive (RX) wire
pairs as needed to establish communications with the end device. As a result, the
processor is able to transparently interconnect with any other 10/100BASE-T
Ethernet device with either straight-through or crossover cables. Auto-negotiation
is managed independently on each of the four switch ports.
multi-addressing The switch learns the switching parameters for up to 1024 MAC
addresses. The switch deletes inactive address entries (those exceeding 300 sec
of inactivity).
tagging The switch transmits data packets unchanged with the VLAN tag, in
accordance with IEEE 802.1q.
store-and-forward The switch stores all the data it receives, checks it for the proper
packet length, and executes a CRC validity check. Packets meeting the criteria
are forwarded to their destination. Packets that do not meet both criteria are
discarded.
queuing An output port that is slow or congested never affects the transmission of
frames to ports that are non-congested. Traffic will always be received on the
input port.

The Ethernet Port Connections
Introduction
The Momentum 171 CBB 970 30 processor contains four 10/100BASE-T ports.
Four RJ45 connectors are provided on the top of the module for connectivity to each
of the four ports (see p. 11).
Wiring
The following figure illustrates a standard pin assignment for the four Ethernet RJ45
connectors. Remember that the switch can automatically change the pin
assignments as a function of its auto-MDI/MDI/X and auto-polarity features
(see p. 24).
Pin 8
Pin 7
TD- Pin 6
Pin 5
Pin 4
TD+ Pin 3
RD- Pin 2
RD+ Pin 1
The TD+/- pair (pins 3 and 6) and the RD+/- pair (pins 1 and 2) are swapped when autoMDI/MDI/X occurs. The switch automatically compensates for this swap.
The RD+ and RD- assignments on pins 1 and 2 are swapped when auto-polarity occurs.
The switch automatically compensates for this swap.
Pins 4 and 5 are shorted together and terminated. This pin assignment is standard for
Ethernet devices.
Pins 7 and 8 are shorted together and terminated. This pin assignment is standard for
Ethernet devices.
Ethernet Cable
Selection
Use Ethernet CAT5E or CAT6 grade cables with EIA568 pinouts to connect devices
to the Ethernet ports on the 171 CBB 970 30 processor. The maximum cable length
between devices is 100 m.
In high noise environments, shielded CAT5, CAT5E, or AT6 cables must be used.

Network Design Considerations
Introduction
In a distributed control environment, the Ethernet ports on a Momentum
171 CBB 970 30 processor can connect to:
z
z
z
a network with distributed I/O and control devices
a supervisory network
a network that combines I/O and supervisory functions
The following discussion examines some network design considerations that can
make communication between related devices as effective and deterministic as
possible.
Concurrent
Communication
A maximum of 96 devices can communicate with the Momentum 171 CBB 970 30
processor at any one time over Ethernet. The types of devices and the maximum
number of each device type are as follows:
z
z
z
z
2 programming panels (one of which must be in monitor mode)
14 general-purpose Modbus server paths
16 MSTR elements (MSTR elements support Modbus Read, Modbus Write, and
Modbus Read/Write commands)
64 cyclic configured data slave paths
Obtaining
Network MAC
and IP
Addresses
When installed on a new network, the Momentum171 CBB 970 30 processor
obtains the MAC addresses and IP addresses of the other Ethernet devices on the
network. This process may require several minutes.
Operating
without Battery
Back-up
When the processor is successfully communicating with these devices and battery
back-up is not present, we recommend that you stop the processor and save your
program to Flash, using Concept (see p. 67) or ProWORX 32 (see p. 89). This
saves the processor’s ARP cache and enables it to restore the information rapidly if
power is lost or removed. If you do not save to Flash, the processor must reacquire
the ARP cache information from the network.
Note: Preserve your ARP cache information.
This procedure should also be followed whenever:
z
z
26
a new or substitute device is installed on the network
the IP address of a network device has been changed
31007547 1/2007
The Ethernet Switch
Managing
Distributed I/O
over Ethernet
In an Ethernet I/O network, the Momentum171 CBB 970 30 processor controls
distributed I/O modules equipped with Ethernet interfaces and other Transparent
Ready Ethernet devices. Some examples include Advantys STB I/O islands and
Momentum distributed I/O modules.
The Momentum171 CBB 970 30 processor provides isolation from both MIS data
traffic and unrelated communication between other control devices. Traffic from MIS
data networks can interrupt communication between control devices, causing your
control application to behave unpredictably. The high message rates that may be
generated between the Momentum 171 CBB 970 30 processor and I/O devices may
bog down an MIS network, causing loss of productivity.
CAUTION
UNPREDICTABLE NETWORK BEHAVIOR
Use switches or separate networks to isolate the Momentum 171 CBB 970 30
processor and related devices from MIS data networks.
Failure to follow this instruction can result in injury or equipment damage.
Supervisory
Networks
31007547 1/2007
In a supervisory architecture, several intelligent processing devices share system
data. Many kinds of devices may be part of the network. Be aware of each device
requirement for access to the network and of the impact each device can have on
the timing of your network communications.
27
The Ethernet Switch
Network Security Firewalls
Overview
To restrict access to your Momentum 171 CBB 970 30 processor and to the I/O
network, you may want to consider a firewall. A firewall is a gateway that controls
access to your network. There are two types of firewalls:
z
z
network-level firewalls
application-level firewalls
Network-level
Firewalls
Network-level firewalls are frequently installed between the Internet and a single
point of entry to an internal, protected network.
Application-level
Firewalls
An application-level firewall acts on behalf of an application. It intercepts all traffic
destined for that application and decides whether to forward that traffic to the
application. Application-level firewalls reside on individual host computers.

The Ethernet Switch
Assigning Ethernet Address Parameters
IP and MAC
Addresses
The Momentum 171 CBB 970 30 processor is shipped from the factory without an
IP address assignment. At initial start-up, the processor attempts to obtain an IP
address from a BOOTP or DHCP server.
A MAC address is set for every processor at the factory.
Ethernet IP address, default gateway, and subnetwork mask parameters can be
assigned with one of following applications:
z
z
z

Obtaining an IP
Address
CAUTION
UNPREDICTABLE NETWORK OPERATIONS
Make sure that your Momentum 171 CBB 970 30 processor has a unique IP
address on the Ethernet network.
Failure to follow this instruction can result in injury or equipment damage.
CAUTION
COMMUNICATION ERRORS
After taking the Momentum 171 CBB 970 30 processor out of service, clear the
program and IP address to prevent future conflicts.
To clear the IP address:
z Go to the Ethernet I/O Scanner dialog in Concept (see p. 58) or the
Configuration Extensions dialog in ProWORX 32, and make sure that the IP
address acquisition method is set to use a BOOTP server.
z With the BOOTP method selected, save the configuration to Flash.
z Then decommission the processor.
Before installing a replacement Momentum 171 CBB 970 30 processor on your
network, verify that it contains the correct IP address and program for your
application.
Failure to follow this instruction can result in injury or equipment damage.
31007547 1/2007
29
The Ethernet Switch
On start-up, an unconfigured processor attempts to obtain an IP address by issuing
BOOTP requests. When a response from a BOOTP or DHCP server is obtained,
that IP address is used.
Consult your system administrator to obtain a valid IP address and appropriate
gateway and subnet mask, if required.
Each IP address on the Ethernet network must be unique. The 171 CBB 970 30
processor checks for duplicate IP addresses on the network before it actively starts
network operations.
If for any reason two or more devices coexist on an Ethernet network with the same
IP address, network operations are unpredictable.
BOOTP and
DHCP Servers
A BOOTP or DHCP server is a program that manages the IP addresses assigned to
devices on the network. Your system administrator can confirm whether a BOOTP
or DHCP server exists on your network and can help you use the server to maintain
the 171 CBB 970 30 processor’s IP address.
Retaining The IP
Address Setting
If the processor has lost its battery back-up capability and you want the IP address
setting to be retained after power is removed from the module, save your program
to Flash using Concept (see p. 67) or ProWORX 32 (see p. 89). IP address retention
on restart differs depending on the way the processor is configured.
If a processor without battery back-up is configured to use the BOOTP server
and an IP address was previously saved to Flash, the processor issues three
BOOTP requests 5 sec apart.
z If a BOOTP response is received from the server, the new IP address is
assigned but not automatically saved to Flash. To save the new IP address to
Flash, you need to use your panel software. If a power cycle occurs on the
processor, the IP address that is currently saved to Flash is used.
z If a BOOTP response is not received from the server, the processor uses the
IP address that is saved in Flash. Three ARP broadcasts are made 5 sec apart
to check for duplicate IP addresses. Three additional ARP broadcasts are
made 2 sec apart with the station’s MAC address and IP address.
If a processor without battery back-up is configured for Specify an IP Address
and an IP address was previously saved to Flash, the processor listens for
any BOOTP messages but does not issue any BOOTP requests. It uses the
saved IP address. Three ARP broadcasts are made 5 sec apart to check for a
duplicate IP address. Three additional ARP broadcasts are made 2 sec apart with
the station’s MAC address and IP address.

Using BOOTP Lite to Assign Address Parameters
The BOOTP LIte
Alternative
Instead of a BOOTP or DHCP server, Schneider Electric’s BOOTP Lite utility
software can be used to provide the IP address, subnet mask, and default gateway
to the processor.
Note: BOOTP Lite and the user document are available for download at
www.telemecanique.com.
Using the
Correct MAC
Address
CAUTION
UNINTENDED OPERATION
z
z
Enter the parameters of the target controller (as described in the BOOTP Lite
user manual). Otherwise, the controller runs on its old, or existing, configuration.
Verify the MAC address of the target device before invoking the BOOTP Lite
Server Software.
Failure to follow this instruction can result in injury or equipment damage.
An incorrect MAC address may result in an unwanted change to another device or
cause unexpected results.
Specifying
Addresses/
Stopping the
Processor
A response from BOOTP Lite causes the processor to enter Stopped state on
completion of power-up, if the processor has been set to Specify IP Address mode
in Concept. This is useful when inappropriate outbound network traffic might result
if the processor immediately transitioned into Run mode after power-up.
Refer to the BOOTP Lite user documentation for instructions.

Reading Ethernet Network Statistics
Overview
Ethernet network statistics are stored in the Momentum 171 CBB 970 30 processor.
They can be viewed with the processor’s on-board Web server.
Table of
Statistics
Network statistics occupy words 0...37 in the Modbus status table:
Word
Data
Description
00 ... 02 MAC Address
03
Board Status
04, 05
Rx Interrupt
Number of frames received by this station. Only broadcast
frames pertinent to this station and individual address match
frames are received and counted.
06, 07
Tx Interrupt
Number of frames transmitted from this station. Includes all
transmitted broadcast frames for ARP and BOOTP.
08, 09
Not used.
10, 11
Total Collisions
This field should always be 0.
12, 13
Rx Missed
Packet Errors
Receive frame was missed because no buffer space was
available to store the frame. Indicates firmware unable to keep up
with link. The only time this should increment is during a saveuser-logic-to-Flash operation, when all interrupts are disabled for
10 sec.

Framing Errors
(Giant Frame
Error)
Counts the number of received frames addressed to this node
that are longer than 320 bytes. Any such large frame has no
relevance to the 171 CBB 970 30 processor and is skipped. This
error should not occur.
20, 21
Overflow Errors Increments whenever a received frame cannot be copied into the
frame buffer because the frame buffer is full. This situation should
never occur under legal Ethernet traffic.
22, 23
CRC Errors
Low Word: Peak Collision Detector (should always be 0)
Increments when a packet is received with any of the following:
z CRC error
z Extra data error
z Runt error
32
31007547 1/2007
The Ethernet Switch
24, 25
Receive Buffer
Errors (Out of
Server Paths)
Increments when a client attempts and fails to connect to an
Ethernet port because there is no available server path. The
Ethernet switch in the 171 CBB 970 30 processor will support 14
simultaneous data paths and 2 program paths before this counter
increments. This error indicates a poor application architecture.
26, 27
Transmit Buffer
Errors
Increments when the 171 CBB 970 30 processor cannot transmit
an Ethernet response frame because all frame buffers are used.
For example, if all of the processor’s 16 PING buffers contain
PING replies that are ready to be transmitted but the
transmission is delayed because of collisions and back-off, any
newly received PING requests are discarded and the counter is
incremented. This error can occur for PING, ARP, and
connection attempts to a server path. Although this error is
theoretically possible, it is rare.
28, 29
Silo Underflow
(TCP retries)
This field counts processor TCP/IP retries. All processor clients
and servers use the TCP/IP protocol, which implements
sequence numbers and time-outs. Whenever TCP/IP data is
pushed from the processor, the processor must receive an
acknowledgment of the receipt of data within the time-out period.
If not, the processor issues a retry. Retries may result from any
of the following conditions:
z The original data frame was garbled, corrupted, and lost
z The target TCP/IP stack is operating more slowly than the
processor retry rate
For Modbus 502 servers, the processor initiates retries after (1,
1, 2, 2, 4, 8) sec.
For Modbus 502 clients, the processor retry rate is the larger of:
z 1/4 the health timeout for Ethernet I/O Scanner data
z 4 times the previous measured TCP/IP round trip time for i/o
Scanner MSTR block
31007547 1/2007
30, 31
Late Collision
Increments when the transmit frame process is aborted because
of a late collision detection (after the first 64 bytes of the frame
were transmitted collision-free). This field should always be 0.
32, 33
Lost Carrier
Although this error is theoretically possible, it is rare.
Note If you see a non-zero value, please report it to your
Schneider Electric Service Representative.
34, 35
16 Collision Tx
Failure
Transmit frame process aborted after 16 consecutive collisions.
The frame was not successfully transmitted onto the Ethernet
link. This error should never occur.

Cables and Adapters for a Modbus RS232 Connection
Overview
To connect a computer or other host device to the 171 CBB 970 30 processor’s
Modbus port, you need a cable with an RJ45 connector on one end and a connector
suitable for host device on the other end. Schneider Electric provides pre-made
Modbus cables in three lengths and two types of SUB-D adapters that can be used
for an RS232 connection to most computers.
Modbus Port
Cables
Schneider Electric’s three pre-made Modbus cables are standard eight-position, foilshielded, flat telephone cables with male RJ45 connectors on each end. One RJ45
connector plugs into the Modbus serial port, and the other plugs into a female SUBD adapter that fits onto the programming station.

RS485 Communication Capabilities
The RS485 protocol handles messaging over long distances with higher level of
noise immunity than RS232 without the need for modems. RS485 supports two-wire
or four-wire cabling. A multimaster/slave system must use two-wire cabling. A single
master/slave system may use two- or four-wire cabling.
Details on cabling and accessories for RS485 networks are described in an
appendix (see p. 103).

Changing the Size of the Full Logic Area
Introduction
The number displayed in the Available Logic Area field in the PLC Configuration
screen indicates the amount of memory available for application logic. You cannot
directly enter this field to modify the value. You can, however, change the amount of
memory available by manipulating the sizes in other fields in the PLC Configuration
screen.
Example 1
For example, if you reduce the expansion size of the I/O map, the number in the
Available Logic Area field automatically increases. Say you are using a 12.2K
machine and you change the size of the I/O map from 512 to 256. The Available
Logic Area automatically increases by 256 words from 1198 to 1454.
Example 2
If you allocate some number of words to Peer Cop expansion, you reduce the
Available Logic Area by the number of words allocated for Peer Cop.

If you designate a 3x register (as shown in the example above), the health bits for
64 transactions (maximum) are stored in 4 contiguous registers starting at the
address you specify.
If you designate a 1x discrete input reference, the health bits are stored in 64
contiguous registers, using 1 bit/register.
A health bit is set only if the associated transaction completes successfully within the

Diagnostic Block
If an you want to display Ethernet diagnostic information on your I/O scanner
transactions, check the box next to the Diagnostic Block (3x/4x) entry (just below
the Health Block (3x/4x) entry, and enter a starting reference in the window. The
reference may be either a 3x or a 4x register. The system automatically reserves 64
contiguous registers starting with the reference value you enter.
When the box is checked, a new column called Diag Code appears in the Ethernet
I/O Scanner dialog. Whenever a diagnostic error is detected, a hexadecimal integer
code appears in this Diag Code column. The meanings of these diagnostic codes
are described in an appendix (see p. 100).
IP Address
Type the IP address of the slave module in the IP Address column (item 1 below).

Parameters –
Health Block
Once you have established communication with the controller, you may assign
parameters for I/O scanning (see p. 64).
Specify the starting register of the register block which will contain the health bits for
each of the I/O Scanner transactions that you intend to configure.
If you designate a 3x register, the health bits for 64 transactions (maximum) will be
stored in 4 contiguous registers starting at the address you specify.
If you designate a 1x register, the health bits will be stored in 64 contiguous discrete
registers.
A health bit is set only if the associated transaction has completed successfully
within the last health timeout period for that transaction. When the PLC is started, all
configured transactions have their respective health bit preset to 1. If the transaction
subsequently fails, then the health bit is cleared after the programmed health
timeout period has expired.
Additional health bits can be viewed by clicking on the PLC Status icon located in
the project tree.

Logic Solve Time
See the scan time formula below
for the 984LL Exec
The following formula applies to a Momentum 171 CBB 970 30 processor using the
984LL exec.
scan time = (0.25 ms/Ethernet device + 0.002 ms/word) + 0.13 ms/K of logic +
0.40 ms
Note: Modbus messages add from 1 to 2 ms per scan, depending on the length of
the message.
31007547 1/2007
93
Specifications
Note: The formula above presumes that all MSTR blocks and all configured
connections are set to go as fast as possible. When these conditions are true, the
Momentum processor attempts to exchange data with each device once per scan.
Note: If several devices are configured to communicate on a timed basis that is
substantially larger than the scan time calculated, then the communications to
those devices will be spread out over several scans.
Example
You have 3 drops of Ethernet I/O modules connected to one 171 CBB 970 30
processor. The processor has a configured time of 50 ms each, and a total of 4k
user logic. The scan time for all modules configured as fast as possible is
75 ms + 0.12 ms + 0.52 ms = 1.79 ms.

Two-Wire Cabling Schemes for Modbus RS485 Networks Connecting
Momentum Components
Introduction
Two-wire cabling schemes may be used for single master/slave or multimaster/
slave communications. Masters may be located anywhere in the network.
CAUTION
POTENTIAL FOR MULTIMASTER CONFLICTS
Conflicting messages to a slave module can cause problems.
z Configure a multimaster network carefully to avoid masters issuing
simultaneous or conflicting commands to the same slave module.
Failure to follow this instruction can result in injury or equipment damage.
Length
The maximum length of cable from one end of network to other is 2000 ft. (609 m).
Number of
Devices
The maximum number of devices in a network is 64 if all are Momentum devices.
Otherwise, the maximum is 32.
Termination
One end of the cable run must be terminated with a terminating resistor (color code
is red).
The other end of the cable must be terminated with a terminating shunt, which
connects the transmit pair to the receiver pair (color code is blue).
