3.1
Using the Sample Program
The sample program consists of user defined data types, controller tags and
ladder rungs that allow communication between the CompactLogix or MicroLogix
processor, the MVI69-HART module, and the HART network. You can use the
sample program as-is, or you can incorporate the data types, controller tags and
ladder rungs into an existing program.
3.1.1 Controller Tags
The MVI69-HART module is defined in the example as HARTData1 to hold all
data related to the database (type HARTData) and HART1 to hold all status data
related to the module (type HARTModuleDef). The tag name can be set to any
valid tag name desired.
