Sample Project
Ladder
The ladder contained in the sample project is used to perform several different operations.
The main routine in the MainProgram is used to copy data from the user defined tags to
the module local tags. This data includes input, output and configuration settings for the
module.
The OF4IH0_Packet_Data routine in the MainProgram contains the ladder that
demultiplexes the HART data for each individual packet. Refer to Section 7.2 HART
Packet
Data for more information on HART and the HART packets.
The OF4IH0Messaging program contains several routines needed to send and receive
HART messages to and from the module and the connected HART devices.
