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.
I/O Connection
This module is assigned a unique module address between 0
and 3. No other HART-type module may use this module
address.
Notes
The hart5904 module does not send commands to the HART devices. Use the hart0, hart1,
hart2, hart3 or hart33 function blocks to send commands to HART devices.
Refer to the 5904 HART Interface Module manual for further information.
