Modbus TCP/IP to Hart Analog Gateway
5208-MNET-HART
5228-MNET-HART
Product Description
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.
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.
Product Applications
ProSoft Configuration Builder (PCB) provides a quick and easy way to manage module configuration files and view module and network diagnostics. 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.
Functional Specifications
Internal Database
The ProLinx module contains an internal database that consists of areas for application data, status information, and configuration information.
The internal database is shared between all ports on the module and is used as a conduit to pass information from a device on one network to one or more devices on another network.
Application Data Area
The data area is used to store and retrieve data by the protocol drivers and for data exchange between protocols. The database is used as a source for write commands to remote devices and holds data collected from the remote devices. Commands defined in the configuration file (stored in the configuration data area) control how the data is to be handled in the database.
Status Data Area
This area is used to store error codes, counters, and port status information for each port.
Configuration File
This file contains module configuration information such as port configuration, network information, and command configuration. This configuration file is downloaded to, or uploaded from, the module.
Modbus TCP/IP Protocol Specifications
The Ethernet driver interfaces with a common internal database in the module. This permits the sharing of data across many different protocols and networks.
Modbus TCP/IP Port Specifications
Server
The MNET module supports server functionality using the reserved Modbus TCP/IP service port 502, as well as service port 2000 to support the TCP/IP encapsulated Modbus protocol that is supported by several HMI manufacturers. Services supported in the module permit client applications (i.e., HMI software packages, Quantum processors, etc.) to read from and write to the module's database.
Data in the module'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.
There is no configuration of the MNET module required to implement Server functionality other than setting up the network and database parameters in the user configuration file.

|
|
Command List
|
Up to 100 commands on the Client port, each fully configurable for function, Server IP address, Service Port, register to/from addressing and word/bit count
|
|
Status Data
|
Error codes available on an individual command basis.
|
|
Polling of command list
|
User configurable polling of commands, including disabled, continuous and on change of data (write only)
|
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.
