The MVI69-HART Multi-drop Master Communication Module is designed to allow CompactLogix / MicroLogix processors to interface easily with HART compatible devices. Devices commonly supporting the protocol include pressure, temperature, flow transmitters, as well as other similar instruments commonly found in the process (and other) industry.

The MVI69-HART Master Communication Module allows Rockwell Automation CompactLogix / MicroLogix compatible processors to easily communicate with HART slave devices. The MVI69-HART module interfaces up to 15 devices on each HART channel with the processor. HART 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 CompactLogix / MicroLogix processor backplane using the internal database contained in the module and direct control by the processor’s ladder logic and pre-defined data objects (5000 registers maximum).

The MVI69-HART module is the perfect solution for industrial applications in chemical and refining operations, gas and liquid distribution systems, and remote offshore monitoring stations, addressing virtually all aspects of control, data acquisition, and maintenance.

Features and Benefits

  • Single-slot - 1769 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 memory and processor controller tags. A sample ladder file with AOI is included
  • Configuration data obtained from configuration text file downloaded to module. A sample configuration file is included.
  • Supports CompactLogix and MicroLogix 1500 LRP Controllers except 1769-QBFC1B, 1769-L16x, and 1769-L18x


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.
