Chapter 7
Enabling and Using HART on
the 1769sc-OF4IH
This chapter outlines the detailed settings and configuration related to HART
communication for the 1769sc-OF4IH module. These settings determine how the module
acquires HART data.
The chapter is broken down into the following sections:
Configuring the module for HART
HART Packet Data
Sending and Receiving Messages
Module Specific Commands
HART protocol overview
The ladder samples and tags referenced in this chapter were created
for the Compact Logix controller using RSLogix 5000 software, see
Chapter 4. If you plan on using a MicroLogix 1500 controller, refer to
Chapter 5.
Section 7.1
Configuring the
Module for HART
7.1.1 Configuring the OF4IH Module for (Hart
Acquisition/Communication)
In order for HART to be active on any given channel, the channel configuration must
contain the following basic settings:
The channel must be enabled, set for 4 to 20 mA and the enable HART checkbox must be
checked. See figure below.
