Description

Prosoft PLC Module MVI56-HART

• Extended Product Type : Module

• Product ID: MVI56-HART

• Prosoft Type Designation : Module

Features and Benefits

The MVI56-HART Master Communication Module allows Rockwell Automation ControlLogix I/O compatible processors to easily communicate with HART slave devices. The MVI56-HART module interfaces up to 15 devices on each HART channel with the Rockwell Automation ControlLogix processor. Four channels on the module support master protocol commands to interface with slave devices on their own networks. Each port is individually configurable. Data is exchanged between the HART network and the Rockwell Automation ControlLogix processor backplane using the internal database contained in the module and direct control by the controller’s ladder logic and pre-defined data objects (5000 registers maximum).

The MVI56-HART module is the perfect solution for industrial applications in chemical and refining operations, to gas and liquid distribution systems, and remote offshore monitoring stations are addressing virtually all aspects of control, data acquisition, and maintenance.

Applications

The HART protocol is supported by major instrument suppliers and the HART Communication Foundation (HCF).

Today, HART is the most widely used digital communications protocol for instruments in the process control industry. More than 105 manufacturers support HART with a choice of more than 170 different field instruments.

Specification

• Single Slot – 1756 backplane compatible
• The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module
• Ladder Logic is used for data transfer between module and processor. Sample ladder file included.

Configuration data obtained from configuration text file downloaded to module. Sample configuration file included

• Local or remote rack
• The MVI56-HART module supports the HART Multi-drop implementation of the protocol. Following are some general specifications for the module:
•  Built in accordance to the HART Bell 202 Frequency Shift Keying (FSK) standard to superimpose digital signals at a low level on top of the 4 to 20mA
• Four independent HART master ports that are completely user-configurable

• Supports up to 15 devices per port

• Point-to-point (slave address 0) or Multi-drop (slave address 1 to 15) modes supported
• Supports 99 universal and common practice commands per port to control and monitor devices with integer, IEEE754 floating-point and packed ASCII character string data blocks
• Burst mode can be used for faster update of data from a single slave
• Supports an auto polling feature that will automatically collect data from each HART instrument on the channel and store the data in the module database
• Communication ports can be configured as a secondary master (that is, handheld configuration device)
