The ProLinx Modbus TCP/IP (MNET) driver can be used to interface many

different protocols into the Schneider Electric Quantum family of processors as

well other devices supporting the protocol. The MNET driver supports Client

connections as well as Server connections, and, with the addition of the WEB

hardware option, the gateway also provides HTTP, FTP and Email capability.

The Ethernet driver interfaces with a common internal database in the gateway.

This permits the sharing of data across many different protocols and networks.

The following illustration shows the functionality of the MNET driver.

Driver Manual Modbus TCP/IP Interface Module

Page 10 of 78 ProSoft Technology, Inc.

1.1 Modbus TCP/IP (MNET) Port

The gateway supports a client connection on the TCP/IP network to interface

with processors (and other server based devices) using a user constructed

command list of up to 100 entries. The gateway’s internal database is used as

the source for write commands to the remote processors. Data collected from the

processors using read commands is placed in the gateway’s database.

Data in the gateway’s internal database is accessible for read and write

operations by any node on the network supporting the MBAP (Service Port 502)

or MNET (Service Ports 2000/2001) TCP/IP protocols. The MBAP protocol (Port

502) is a standard implementation defined by Schneider Automation and used on

their Quantum Processor. This open protocol is a modified version of the serial

Modbus protocol. The MNET protocol is an embedded Modbus protocol

message in a TCP/IP packet. The gateway supports up to five active server

connections on Service Ports 502, five additional active server connections on

Service Port 2000, and one active client connection.

1.3 Modbus TCP/IP

ProSoft’s Modbus TCP/IP implementation uses the module’s shared internal

memory for data transfer. Sharing the memory with another protocol driver allows

the module to transfer data between Modbus TCP/IP devices and other devices

on other networks.

Configurable floating-point data movement is supported, including support for

Enron or Daniel

floating-point applications.

Modbus TCP/IP Server (Slave)

The server driver accepts incoming connections on Service Port 502 for clients

using Modbus TCP/IP MBAP messages and from clients on Service Port 2000

(or other Service Ports) for clients using Encapsulated Modbus messages..

 Supports five independent server connections for Service Port 502 (MBAP)

 Supports five independent server connections for Service Port 2000

(Encapsulated)

 Supports a total Modbus TCP/IP data transfer capacity of up to 4000

registers or up to 64,000 bits in any combination of data types throughout the

memory database

 Modbus data types overlap in the gateway’s memory database, so the same

data can be conveniently read or written as bit-level or register-level data.

Modbus TCP/IP Client (Master)

 Actively reads data from and writes data to Modbus TCP/IP devices, using

MBAP or Encapsulated Modbus message formats

 Offers one client connection with up to 100 commands to talk to multiple

severs

1.4 Internal Database

Central to the functionality of the gateway is the internal database. This database

is shared between all the ports on the gateway and is used as a conduit to pass

information from one device on one network to one or more devices on another

network. This permits data from devices on one communication port to be viewed

and controlled by devices on another port.

In addition to data from the Server and Client ports, status and error information

generated by the gateway can also be mapped into the internal database.

1.4.1 Modbus TCP/IP Client Access to Database

The client functionality exchanges data between MNET module's internal

database and data tables established in one or more Quantum processors or

other server based devices. The command list, defined in the user configuration,

defines what data is to be transferred between the module and each of the

servers on the network. No ladder logic is required in the processor (server) for

client functionality, except to assure that sufficient data memory exists.

The following illustration describes the flow of data between the Ethernet clients

and the internal database.

1.4.2 Modbus TCP/IP Server Access to Database

The MNET gateway provides server functionality using reserved Service Port

502 for Modbus TCP/IP MBAP messages, as well as Service Ports 2000 and

2001 to support the TCP/IP Encapsulated Modbus version of the protocol used

by several HMI manufacturers. Server support in the gateway permits client

applications (that is, HMI software, Quantum processors, and so on) to read from

and write to the gateway’s database. This document discusses the requirements

for attaching to the gateway using client applications.

Functional Overview MNET ♦ ProLinx Gateway

Driver Manual Modbus TCP/IP Interface Module

Page 14 of 78 ProSoft Technology, Inc.

September 1, 2010

The Server driver is able to support multiple concurrent connections from several

Clients. Up to five (5) Clients can simultaneously connect on Service Port 502

and five (5) more can also simultaneously connect on Service Port 2000. Service

Port 2001 is used by the MNET driver to pass Encapsulated Modbus commands

through from the Ethernet port to the gateway’s serial port (Modbus pass-through

support is available on 5201-MNET-MCM and 5202-MNET-MCM4 models only).

When configured as a Server, the internal database of the MNET gateway is

used as the source for read requests and the destination for write requests from

remote clients. Access to the database is controlled by the command type

received in the incoming message from the Client. The following table defines the

relationship of the gateway’s internal database to the addresses required in the

incoming Modbus TCP/IP requests:

Database Address Modbus Address

0 40001

1000 41001

2000 42001

3000 43001

3999 44000

The following virtual addresses are not part of the normal gateway user database

and are not valid addresses for standard data. However, these addresses may

be used for incoming commands that are requesting floating-point data. To use

addresses in this upper range requires you to set the Float Flag to Yes, the Float

Start to a database address in the range below, and the Float Offset to a

database address in the gateway user memory area shown above. Remember

that, once you do this, all data above the Float Start address must be floating-

point data.

Database Address Modbus Address

4000 44001

5000 45001

6000 46001

7000 47001

8000 48001

9000 49001

9999 50000

The MNET gateway must be correctly configured and connected to the network

before you attempt to use it. Use a network verification program, such as the

command prompt PING instruction, to verify that the gateway can be seen on the

network. Use ProSoft Configuration Builder to confirm proper configuration of the

gateway and to transfer the configuration files to and from the gateway.

1.4.3 Modbus Message Routing: Port 2001

When Modbus messages are sent to the module over the TCP/IP connection to

port 2001, the messages are sent (routed in the module) directly out the serial

communication port (Port 0, if it is configured as a Modbus Master. The

commands (whether a read or a write command) are immediately routed to the

slave devices on the serial port. Response messages from the slave devices are

routed to the TCP/IP network to be received by the originating host.

2.3 [MNET Servers]

This section contains database offset information used by the servers when

accessed by external clients. These offsets can be utilized to segment the

database by data type.

2.3.1 Float Flag

Yes or No

This flag specifies if the floating-point data access functionality is to be

implemented. If the float flag is set to Yes, Modbus functions 3, 6, and 16 will

interpret floating-point values for registers as specified by the two following

parameters.

2.3.2 Float Start

0 to 32767

This parameter defines the first register of floating-point data. All requests with

data requests. This parameter is only used if the Float Flag is enabled. For

example, if a value of 7000 is entered, all requests for registers 7000 and above

will be considered as floating-point data.

2.3.3 Float Offset

0 to 4999

This parameter defines the start register for floating-point data in the internal

database. This parameter is used only if the Float Flag is enabled. For example,

if the Float Offset value is set to 3000 and the float start parameter is set to 7000,

data requests for register 7000 will use the internal Modbus register 3000.
