HART commands and parameters
You can use
SIMATIC PDM to set the parameters of the HART field devices via HART
commands and read these out via HART replies. The HART commands and their
parameters are divided into three groups with the following properties:
●
universal
●
generally usable
●
device specific
Universal command must be supported by all manufacturers of HART field devices; it is
recommended that generally useable commands be supported. In addition there are device-
specific commands, which only apply to the specific field device.
Examples of HART parameters
The following table shows HART parameters of various groups:
