Battery Life Advisory

Note: Modules manufactured after April 1st, 2011 do not contain a battery. For modules

manufactured before that date the following applies:

The module uses a rechargeable Lithium Vanadium Pentoxide battery to back up the real-time clock and CMOS
settings. The battery itself should last for the life of the module. However, if left in an unpowered state for 14 to 21
days, the battery may become fully discharged and require recharging by being placed in a powered-up ControlLogix
chassis. The time required to fully recharge the battery may be as long as 24 hours.

Once it is fully charged, the battery provides backup power for the CMOS setup and the real-time clock for
approximately 21 days. Before you remove a module from its power source, ensure that the battery within the module
is fully charged (the BATT LED on the front of the module goes OFF when the battery is fully charged). If the battery
is allowed to become fully discharged, the module will revert to the default BIOS and clock settings.

Note: The battery is not user-replaceable or serviceable.

1.3 Package Contents

The following components are included with your MVI56E-FLN module, and are
all required for installation and configuration.

Important: Before beginning the installation, please verify that all of the following
items are present.

If any of these components is missing, please contact ProSoft Technology
Support for replacement parts.

Page 12 of 155 ProSoft Technology, Inc.

MVI56E-FLN ♦ ControlLogix Platform Start Here
FA Control Network Ethernet Communication Module User Manual

1.4 Setting Jumpers

The Setup Jumper acts as "write protection" for the module’s flash memory. In
"write protected" mode, the Setup pins are not connected, and the module’s

firmware cannot be overwritten. Do not jumper the Setup pins together unless
you are directed to do so by ProSoft Technical Support.

The following illustration shows the MVI56E-FLN jumper configuration.

Note: If you are installing the module in a remote rack, you may prefer to leave
the Setup pins jumpered. That way, you can update the module’s firmware
without requiring physical access to the module.

Security considerations:
Leaving the Setup pin jumpered leaves the module open to unexpected firmware

updates.
You should consider segmenting the data flow for security reasons. Per IEC

62443-1-1, you should align with IEC 62443 and implement segmentation of the
control system. Relevant capabilities are firewalls, unidirectional communication,
DMZ. Oil and Gas customers should also see DNVGL-RP-G108 for guidance on
partitioning.

You should practice security by design, per IEC 62443-4-1, including layers of
security and detection. The module relies on overall network security design, as it
is only one component of what should be a defined zone or subnet.

1.5 Installing the Module in the Rack

If you have not already installed and configured your ControlLogix processor and
power supply, please do so before installing the MVI56E-FLN module. Refer to
your Rockwell Automation product documentation for installation instructions.

Warning: You must follow all safety instructions when installing this or any other
electronic devices. Failure to follow safety procedures could result in damage to
hardware or data, or even serious injury or death to personnel. Refer to the
documentation for each device you plan to connect to verify that suitable safety
procedures are in place before installing or servicing the device.

After you have checked the placement of the jumpers, insert the MVI56E-FLN
into the ControlLogix chassis. Use the same technique recommended by
Rockwell Automation to remove and install ControlLogix modules.

You can install or remove ControlLogix system components while chassis power
is applied and the system is operating. However, please note the following
warning.

Warning: When you insert or remove the module while backplane power is on,
an electrical arc can occur. An electrical arc can cause personal injury or
property damage by sending an erroneous signal to your system’s actuators.
This can cause unintended machine motion or loss of process control. Electrical
arcs may also cause an explosion when they happen in a hazardous
environment. Verify that power is removed or the area is non-hazardous before
proceeding.

Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create electrical resistance
that can affect module operation.

2 Configuring the MVI56E-FLN Module

The purpose of this section of the User Manual is to show the MVI56E-FLN
functionality through a typical real-world application. For this example application,
the MVI56E-FLN is shown communicating with a Toyoda FL/ET-T-V2
communication module that transfers the data to a TOYODA PC3JG-P processor
located on the same rack.

For this example, the MVI56E-FLN node address is 40, and the FL/ET-T-V2
module node address is 10.

2.1 Using ProSoft Configuration Builder Software

ProSoft Configuration Builder (PCB) provides a quick and easy way to manage
module configuration files customized to meet your application needs. PCB is not
only a powerful solution for new configuration files, but also allows you to import
information from previously installed (known working) configurations to new
projects.

Note: During startup and initialization, the MVI56E-FLN module receives its
protocol and backplane configuration information from the installed Personality
Module (Compact Flash). Use ProSoft Configuration Builder to configure module
settings and to download changes to the Personality Module.

Area Parameters

The ranges of the top addresses (starting adresses) and sizes of Common
Memory Areas 1 and 2 are as follows.

These parameters can be set from the upper layer or by a network parameter
write message.

When nodes receive a network parameter write message for setting these
parameters, the node secedes from the network and rejoins the network in the
halfway participation status.

Unless they are set from the upper layer, the node is regarded as having no
transmitting area. At this time, however, a token is exchanged.

Configuring Area 1 and Area 2

Each area is defined by its starting address (top address) and word length (size).
The following illustration shows the starting addresses and word lengths used in
the sample application:

Token Watchdog Time

1 to 255 milliseconds
The Token Watchdog Time (also known as Token Monitoring Time) value is

unique for each node and is set from the FA link protocol upper layer as the initial
value. If this value is not set, the node is inoperable.

The Token Watchdog Time is notified to all nodes as information on the frame
header. Each node uses the value on the frame from each node as a value of the
monitoring time until the token-holding node releases the token.

Minimum Frame Interval Time

0 to 50 (in units of 100 milliseconds)
This interval value is a unique for each node and is set from the FA link protocol

upper layer as the initial value. If this value is not set, the node is inoperable.
The allowable minimum frame interval means
 The time interval between reception of a token by a node and and

transmission of any frame from the node
or
 The time interval between frames transmitted (from the end of the previous

frame until the beginning of the next frame) The allowable minimum frame

interval of each node is notified to all nodes as information on the frame

header. Each node obtains the maximum value from it and recognizes it as

the allowable minimum frame interval to use.

Important Note: For this module to operate correctly on an FL-net network, the
Minimum Frame Interval Time must be set to a value of 20 or more for all nodes
on the network. If nodes on the network have values less than 20 for this
parameter, the module may not be able to join the network.

2.2.2 Ethernet Configuration

Use this procedure to modify the temporary Ethernet settings you set for your
module in the section on Setting Up a Temporary IP Address (page 17). Here
you assign two sets of IP address, subnet mask, and gateway address values,
one for each of the two Ethernet ports on the module. The IP address for
module's E1 port, which is used exclusively for configuring the module, is entered
in the my_ip parameter set. The IP address for the module's E2 port, which is
used exclusively for the FL-net network data transfer application, is entered in the
my_ip1 parameter set.

1 Determine the network settings for the two ports on your module, with the

help of your network administrator if necessary. You will need the following
information:

For the configuration port E1:

o my_ip - IP address (fixed IP req.) _____ . _____ . _____ . _____
o netmask - Subnet mask _____ . _____ . _____ . _____
o gateway - Gateway address _____ . _____ . _____ . _____

For the FL-net application port E2:

o my_ip1 - IP address (fixed IP req.) _192_ . _168_ . _250_ . _XXX_
o netmask - Subnet mask _____ . _____ . _____ . _____
o gateway - Gateway address _____ . _____ . _____ . _____

Note: The gateway address is optional, and is not required for networks that do
not use a default gateway.

The last octet of the my_ip1 address (XXX, above) will be the module's FL-net
node address on the FA Control network.

Note: Both IP addresses must be configured for different networks. This module
will communicate if both IP addresses are located in the same network.

User Manual FA Control Network Ethernet Communication Module

Checking the Participating Node Status

To retrieve the participation node status, the processor must request special
block 2000 (Participation Table Request) from the module. This special block
transfer request allows the processor to retrieve status information for each
participating node. Status registers include:

 upper layer status (ULS)
 allowable minimum frame interval time (MFT)
 allowable refresh cycle time (RCT)
 Area 1 (A1) and Area 2 (A2) settings
 token watchdog time (TW).

Each block can retrieve status for up to 10 participating nodes. The user
application must initially select the number of nodes to retrieve (up to 10) and the
first node address to retrieve.

For example, to retrieve the status for participating node address 10 (1 node
only), set the controller tags as shown in the following illustrations:

Next, trigger the Participation Table Request block (block 2000). To do this, set
the FLNETMODULE.CONTROL.GetParticipation bit to 1. The following rung in
the sample ladder WriteData routine performs the request to the module. The
FLNETMODULE.CONTROL.GetParticipation bit is automatically cleared after the
response is received from the module.

The following rung in the Read Data routine reads the module response
containing the participating node status.

Checking the Log Data

To retrieve the Log Data, the processor must request special block 9250 (Log
Data Block) from the module.

The following rung in the Write Data routine requests block 9250. To trigger this
logic, set the FLNETMODULE.CONTROL.GetParticipation bit to 1.

The processor will eventually receive the block response from the module, and
the following rung in the Write Data routine will automatically clear the
FLNETMODULE.CONTROL.GetParticipation bit and read the block response to
the correct tags.

2.5.4 Transferring Data

The sample ladder logic automatically updates the data with the
FLNETDATA.Output and FLNETDATA.Input controller tags. The Area 1 data is
divided into blocks 1 to 3. The Area 2 data is divided into blocks 4 to 35. Each
block contains up to 240 words of data.

The data received from the remote FL-net node to the MVI56E-FLN module is
automatically "reassembled" from the input blocks into the FLNETDATA.Intput
controller tag (according to each block ID). Also, the data to transfer from the
module to the remote FL-net node is copied from the FLNETDATA.Output
controller tag into the output blocks according to its block ID. This logic is already
handled by the sample ladder program supplied by ProSoft.

For this example, use the following MVI56E-FLN Area1 and Area 2 settings in
the FLNET.CFG configuration file:

Area 1 Top : 0 #0...511 top address for area 1
Area 1 Size : 50 #0...512 area 1 data size in words (0=not used)
Area 2 Top : 0 #0...8191 top address for area 1
Area 2 Size : 100 #0...8192 area 2 data size in words (0=not used)
BP Area 1 Top : 50 #0...511 top address for area 1
BP Area 1 Size: 50 #0...512 area 1 data size in words (0=none transferred)
BP Area 2 Top : 100 #0...8191 top address for area 1
BP Area 2 Size: 100 #0...8192 area 2 data size in words (0=none transferred)

Important: The module only generates the blocks required to transfer the data
you configured. For this example only one Area 1 block and one Area 2 blocks
are required, so only blocks 1 to 4 are used for data transfer. The larger the
areas, the more blocks are required to transfer data (and the more time is
required to update the whole block).

In this example, configure the FL/ET-T-V2 module with the values in the following
illustration:

4.2 Functional Overview

4.2.1 About FL-net Protocol

FL-net is an open FA network that was standardized by the Japan FA Open
Systems Promotion Group (JOP) of the Manufacturing Science and Technology
Center (MSTC) under the Ministry of International Trade and Industry (MITI). It
has been established in the Japan Electrical Manufacturers standards (JEM

1479) and is becoming very popular.
FL-net enables personal computers and FA controllers, such as programmable

controllers (PLCs) or computerized numeric controllers (CNCs), by different
manufacturers to be interconnected, controlled, and monitored, as shown in the
following illustration.

The following illustration shows the positioning of the FL-net.

FL-net (Version 2.00) Unit specifications have been designed to conform to
Japan Electrical Manufacturers standards (JEM 1479: 2001). It cannot be
connected to communications devices based on the previous standards (JEM
1479: 2000).

The most recent FL-net specifications can be downloaded from the home page of
the Japan Electrical Manufacturers Association (http://www.jema­net.or.jp/Japanese/hyojun/opcn_e/opcn07.htm (http://www.jema­net.or.jp/japanese/hyojun/opcn_e/opcn07.htm)

transmission.

Cyclic Transmission

Cyclic transmission is used to exchange data between nodes. The data is shared
by each node through the Common Memory (shared memory) function.

Basic functions:

 Cyclic transmission implements Common Memory interface.
 Each node transmits its entire memory content while it holds the token.
 Nodes having no cyclic data are acceptable.

With cyclic communications, the Common Memory is refreshed on a fixed cycle
time. Message communications are controlled so that the Common Memory
refresh time does not exceed the allowable refresh cycle time.

Each node constantly monitors the message communications frames that travel
through the network from the time it receives one local-node-directed token until
it receives the next local-node-directed token. When no message
communications frame travels through the network in a single cycle, 120% of the
cycle time value becomes the allowable refresh cycle time. In this way the
allowable refresh cycle time is actively determined according to the number of
nodes in the network.

Common Memory

 The Common Memory interface provides nodes with a service that can be

regarded as a memory shared among them.

 Data on the Common Memory is refreshed cyclically as each node updates

and broadcasts its memory contents.

 Each node broadcasts its data in a fixed cycle and all the nodes in a network

share the same data on the Common Memory.

 A user can use the Common Memory as global area in the node.
 The Common Memory size is 8k bits + 8k words = 8.5k words in a whole

network.

Area 1 and Area 2

 The Common Memory is divided into two areas.
 Area 1 has 512 words and Area 2 has 8192 words (1 word = 2 bytes = 16

bits)

 The maximum quantity of data that can be transmitted by a single node is

8.5k words.

FA Control Network Ethernet Communication Module User Manual

Node Data Area Assignment

 Each node on a FL-net has a specific transmission area in the Common

Memory that does not overlap with others.
 A transmission area assigned to one node must be a receiving area for other

nodes.
 Two data areas can be assigned to a node within Area 1 and Area 2 of the

Common Memory.

 Both areas can be assigned at any word-size within the maximum.
 A node's memory assignment within a Common Memory area is defined by

the top address (starting address) and size of its data area.

Frame Transmission

 Maximum data length of one message frame is 1024 bytes (excluding

header).
 Multiple frames may be used if the transmitting area size exceeds the

maximum frame data size.
 A node receiving multiple frames will update the area only after successfully

receiving all frames from the sending node. Thus time coherency of data from

a node is guaranteed.

Node Having No Common Memory

The FA link protocol allows for the existence of nodes that do not have Common
Memory because they only participate in message transmission, and do not
transmit and receive cyclic data.

User-Defined Specifications

User-defined specifications allow the following range of features that are required
for FA systems.

1 Large-scale network

Up to 254 devices (nodes) can be connected in the physical layer of the
network.
"1 through 254" shall be used as node number. However, numbers "250
through 254" are reserved for maintenance purposes. Number "0" shall not
be used.
Number "255" shall be used as the global address for broadcasting.

2 Dual communications functions to suit application

The Common Memory function uses cyclic transmission so that each node
can always share the same data with other nodes on the network. FL-net also
supports message communications for use when handling only essential data
is required.

3 Large-capacity Common Memory

The Common Memory is provided with a large capacity of 8K bits (Area 1)
and 8K words (Area 2).

4 High-speed response

High-speed response time of 50 milliseconds / 32 nodes (for 2K bits and 2K
words) is provided. The absence of a Master in the FL-net network enables
nodes to be added or removed readily without affecting any other nodes. This
allows any node to be turned ON or OFF easily and facilitates maintenance.

The FL-net protocol is characterized by the following items:

1 Transmission control using masterless token system avoids collision.
2 Refresh cycle time can be specified since the system circulates a token in a

fixed time.

3 The token is transmitted together with cyclic data.
4 The node with a smallest node number among those who participate the

network at start-up time shall start to send the token.

5 If no token is transmitted for a specified period, next node in the token

circulation ring shall send a new token.

6 The masterless token system (characterized by the above two items) will

keep the network from stopping in case of failure of some nodes.

7 The protocol provides information management tables for useful information

to refer operation status of other nodes such as operation mode (RUN /
STOP) and hardware malfunction (ALARM).
