hart5904
HART modem
Description
The hart5904 module provides control of 5904 HART Interface modules. When configured
the module maintains communication with a 5904 HART interface. The hart5904 module
does not have physical I/O channels; instead it returns the 5904 HART interface
communication status as a digital input.
Set the hart5904 module_address to match the address switches on the 5904 HART
interface.
