Modbus Plus to Ethernet Bridge
1.1 Introducing the Ethernet to Modbus Plus Bridge
The Modicon Ethernet to Modbus Plus Bridge provides a transparent multipath
connection between Ethernet host applications and the Modbus Plus industrial
network. The bridge functions as an addressable node on each network,
managing the Ethernet and Modbus Plus protocols and translating messages
between the network applications in both directions.
Ethernet hosts can establish connections to the bridge and send messages
intended for Modbus Plus nodes. The bridge accepts the messages, creates
internal paths for the Modbus Plus transactions, waits for the Modbus Plus token
frame, and forwards the messages to the destination nodes. It receives the data
responses from the Modbus Plus nodes, returns them to the Ethernet hosts, and
closes the paths.
Messages sent to the bridge on either Ethernet or Modbus Plus contain an
embedded Modbus message, consisting of a function code and additional
information such as register addresses and data. The bridge uses the Modbus
function code to determine the type of internal path required for the transaction,
and opens a path if one is available. If a path is not available, a Modbus error
code (exception code) is returned by the bridge to the requesting node.
The bridge provides Modbus Data Master, Data Slave, Program Master, and
Program Slave paths as defined by the Modbus function codes in the messages.
It supports up to eight concurrent Data paths and eight concurrent Program paths.
The bridge supports full five--byte Modbus Plus routing, enabling transactions
through Modicon BP85 Modbus Plus bridges to Modbus Plus nodes on up to three
networks beyond the Ethernet bridge.
Note that Modbus Plus Global Data or Peer Cop messages are not supported
because those types of messages are passed as part of the Modbus Plus token
frame. The token frame is passed among nodes on the local Modbus Plus
network, but is not passed through any bridge devices to other networks.
Figure 1 illustrates a typical bridge connection.

The bridge maintains two internal mapping tables that provide address mapping
between IP addresses (255.255.255.255) and Modbus Plus path addresses
(64.64.64.64.64). The user can define the mapping at a local keyboard and
monitor connection, using a configuration utility that is stored in the bridge.
Mapping tables can also be downloaded by HTTP from the Ethernet host to the
bridge. If neither method is used, the bridge provides default mapping tables.
The user can assign the bridge’s IP address through a BOOTP server using the
bridge’s MAC address, or locally by means of the bridge’s configuration utility.
The bridge’s Modbus Plus address is assigned in hardware switches on the
bridge’s Modbus Plus card.
The bridge is supplied with brackets for mounting on a vertical panel or horizontal
shelf. Its rear panel has connectors for the networks and for operating power, and
LED indicators for the power, Ethernet and Modbus Plus communication status.

1.2 Bridge Message Transactions and Paths
Two types of messages can be initiated to Modbus Plus nodes using Modbus
commands. Programming messages are used for logging into a node and
controlling it, as in load/record/verify operations. Data access messages are used
to read or write data at the node, or to get statistics from the node.
When a message transaction is initiated, a logical path is established between the
originating node and destination node. The path is maintained until the transaction
is completed. The type of path that is set in each device is determined by the
Modbus command embedded in the message.
Table 1 summarizes the four possible types of Modbus Plus paths. The bridge
supports up to eight paths of each type.
Table 1 Modbus Plus Path Types
Path Type Opened in Node Opened for Modbus Command
Data Master (DM) Originator Data access
Data Slave (DS) Destination Data access
Program Master (PM) Originator Programming
Program Slave (PS) Destination Programming
The maximum amount of concurrent TCP/IP connections available in the bridge is
between 8 and 16, depending on the usage of paths in host applications.
For example, up to 16 data connections can be active between TCP/IP hosts and
Modbus Plus nodes (a maximum of 8 active DM paths and 8 active DS paths). Up
to 16 programming paths can be active (8 PM and 8 PS).
If Modsoft software is being used, it sets both a PM and a DM path in the bridge
for each active connection it maintains to a Modbus Plus destination node.
Modsoft could be running on a single host, or simultaneously on multiple hosts.
Thus up to eight TCP/IP connections can be maintained with Modsoft running on
one to eight hosts.
Table 2 summarizes the Modbus function codes which open DM and DS paths in
the respective nodes. For complete information about Modbus commands, see
the Modbus Protocol Reference Guide, publication PI--MBUS--300.

Devices which use the Modbus protocol accept incoming requests for data or
statistics. They reply by returning either a normal or an exception response.
The Modbus function code in the request from an originating node always contains
a most significant bit value of 0 (zero). In a normal Modbus response, the function
code of the originating request is echoed, followed by any requested data or
statistics. In an exception response, the most significant bit is set to 1 (one) to
indicate an error, and the next byte contains an exception code showing the
reason for the error.
Table 3 summarizes the Modbus exception codes which may be returned by the
bridge to the originating node. For further information see the Modbus Protocol
Reference Guide, publication PI--MBUS--300.

Installing the Bridge Hardware
2.1 Overview: Hardware Installation
Here is an overview of the tasks for installing the bridge hardware. The references
are to the sections in this chapter that contain the detailed installation steps.
Setting the Modbus Plus Node Address (Section 2.2)
Before installing the bridge, set its Modbus Plus node address in switches on the
internal Modbus Plus card. The card is accessible by removing the bridge’s cover.
Note that every Modbus Plus node must have a unique address on the network.
The bridge is shipped with the node address set to the default of 1.
Setting the Ethernet Connector Jumper (Section 2.3)
Before installing the bridge, set its internal Ethernet Connector jumper to define
the type of physical cable connection you will be making to the Ethernet. The
bridge has these Ethernet connectors:
H IEEE 802.3 10Base--T unshielded twisted pair cable (UTP RJ--45)
H IEEE 802.3 10Base--5 thick cable (AUI DB--15S)
H IEEE 802.3 10Base--2 thin cable (BNC).
The Ethernet Connector jumper has two positions:
10
H Position 1: RJ--45/BNC connection
H Position 2: AUI connection.
The bridge is shipped with the jumper set to the default RJ--45/BNC position.
Mounting the Bridge Hardware (Section 2.4)
The bridge can be physically installed on a vertical wall panel or horizontal shelf
using mounting brackets supplied with the bridge. Be sure to provide clearance
for ventilation and access to the bridge’s rear panel connectors and indicators.
Connecting the Network and Power Cables (Section 2.5)
Connect the Ethernet and Modbus Plus cables to the bridge’s rear panel. Connect
the power cable and apply power. The bridge has these connectors:
H Ethernet: RJ--45, AUI or BNC (according to your Connector Jumper setting).
H Modbus Plus: Two DB--9S for dual Modbus Plus drop cables.
H Power: Three--prong 110/220 V ac connector.
Installing the Bridge Hardware
CE Installation Requirements (Section 2.6)
If the bridge is being installed at a site that must meet CE requirements, and the
10Base--T (RJ--45) connector is being used, a ferrite bead must be installed on the
Ethernet cable at the RJ--45 connector.
Verifying the Network Communication (Section 2.7)
Check the Ethernet and Modbus Plus LEDs to verify operation of the bridge.

Installing the Bridge Hardware
2.3 Setting the Ethernet Connector Jumper
Do not apply power to the bridge yet. The bridge has three types of Ethernet
connectors:
H IEEE 802.3 10Base--T UTP cable (RJ--45)
H IEEE 802.3 10Base--5 thick cable (AUI)
H IEEE 802.3 10Base--2 thin cable (BNC)
A jumper on the Ethernet card defines the connector to be used. The bridge is
shipped with the jumper set to the default RJ--45/BNC position.
If you intend to use either the RJ--45 or BNC connection, you do not need to
change the jumper position. Continue to the next section in this book.
If you intend to use the AUI connection, you must change the jumper from position
1 to position 2. Remove the Ethernet card, change the jumper, and re--install the
card. Figure 4 shows the jumper location.

Installing the Bridge Hardware
2.6 CE Installation Requirements
If the bridge is being installed at a site that must meet CE requirements, the
following steps must be taken to complete the installation.
Grounding
The bridge must be provided with a direct ground connection of 0.1 ohm or less.
Mounting the bridge on a suitably grounded panel as described in Section 2.4
satisfies this requirement.
In addition the Modbus Plus cable must be grounded to the panel using the ground
wire that is integral to the cable.
Ferrite Bead on RF--45 Cable
If the Ethernet network is being connected to the 10Base--T (RJ--45) connector, an
approved ferrite bead must be installed on the cable at the connector.
The approved bead shown in Figure 9 and in Table 10 is enclosed in a plastic box
which can be clipped over the network cable. It is not necessary to insert the
cable through the bead before you install the RJ--45 connector on the cable.

2.7 Verifying the Network Communication
Refer to Figure 8 for the locations of the bridge’s indicators.
2.7.1 Ethernet Card Indicators
The Ethernet card has an indicator that shows a valid connection between the
card’s RJ--45 (UTP) jack and the network. It has another indicator which flashes
to show’s the bridge’s communication activity on the Ethernet link.
Table 11 Ethernet Card Indicators
Indicator (Green) Status
RJ--45 Connection Valid Valid connection exists at RJ--45 port.
TCP/IP Network Active Bridge is actively communicating TCP/IP.
2.7.2 Modbus Plus Card Indicators
The Modbus Plus card has an indicator that flashes a repetitive pattern to show its
network communication status, plus two indicators which identify communication
errors on the two Modbus Plus cable paths. Note that one error indicator will be lit
normally in single--cable installations, showing that a second cable does not exist.
Table 12 Modbus Plus Active Indicator Patterns
Indicator Pattern (Green) Status
Six flashes/second Normal operating state. All nodes on a
healthy network flash this pattern.
One flash/second The node is off-line. After being in this state
for 5 seconds, the node attempts to go to its
normal operating state.
Two flashes, then OFF for 2 seconds The node detects the network token being
passed among other nodes, but it never
receives the token.
Three flashes, then OFF for 1.7 seconds The node does not detect any token passing
on the network.
Four flashes, then OFF for 1.4 seconds The node has detected another node using
the same address.
