The HART Analog Input Gateway provides a clean way to integrate HART Analog instruments with existing controller platforms on a Modbus TCP/IP network. The gateway works well for field applications where it can be installed closer to HART instrument, saving on copper cable and installation costs. The gateway also saves valuable rack space for other in-chassis options. The gateways provide extremely fast channel update times (all channels updating simultaneously in 67 ms) making the HART Analog Input Gateway ideal for applications where high speeds and point-to-point connectivity are required. These gateways are available in 4 and 8 Analog input channel options.

Особенности и преимущества

The Modbus TCP/IP (MNET) driver can be used to interface many different protocols into the Schneider Electric Quantum family of processors as well other software solutions supporting the protocol. The MNET driver supports Client connections as well as Server connections.

The HART Analog Protocol exists in 4 and 8 channel implementations. This driver can be configured on an individual channel basis to operate as a HART Master Station and supports all the available HART commands including Universal, Common Practice and Device Specific Commands. Each HART channel is independently configured to interface with the internal database in the module.


The ProLinx Communication Modules provide connectivity for two or more dissimilar network types. The modules, encased in sturdy extruded aluminum, are stand-alone DIN-rail mounted protocol gateways, providing communication between many of the most widely used protocols in industrial automation today.

HART Analog Protocol Specification

The HART Analog protocol driver works as a single current loop, point-to-point Master on four channels (all channels set up as channel 0). Each channel is individually configurable.

Protocol Specifications

The auto-poll mode allows the module to automatically collect data from each HART instrument on the channel and store the data in the module's database without the use of user commands. The module automatically generates HART commands 0, 3, 13, 14 and 15.

General Parameters

Communication parameters

Number of HART Preambles: 2 to 50
Enable Handheld: Y or N
Primary Master: Y or N

Configurable Parameters per Channel

Auto-Poll Enable, Short / Long Address Retries, Retries After Error
Poll Time After Error, Number of Commands, Slave List Error Pointer

HART Driver

Command List

Up to 100 fully configurable commands per channel

Polling of command list

User configurable polling of commands, including disabled, continuous, on change of data (write only) and dynamically user or automatic enabled.

MNET Protocol Specification

The Modbus TCP/IP protocol driver can interface many different protocols into Schneider Electric Quantum processors as well other solutions supporting the protocol. The MNET driver supports Client and Server connections, and when coupled with the Web option provides a web/ftp interface as well.

Protocol Specifications

The Modbus TCP/IP driver interfaces with a common internal database in the module. This permits the sharing of data between the Modbus TCP/IP and other networks and devices.

Modbus TCP/IP Server


Server supports up to 5 independent connections each to Modbus TCP/IP clients on Service Port 502 using the standard MBAP protocol, and Service Port 2000.

Configurable Parameters

Module IP Address
Modbus address offsetting

Modbus TCP/IP Client


Actively reads and writes data with Modbus TCP/IP compatible devices.

One client connection (up to 100 servers/devices with 100 commands)

Configurable parameters
