8 PROFIBUS HART INPUT/OUTPUT MODULE (PBHIOM) FUNCTION BLOCK
8.3 Functioning of PBHIOMB
When the PBHIOMB block is activated, it can be used for the following:
Auto-discovery of devices
If the PBHIOMB block is loaded without any HART channels, then it scans the HART devices that are
connected to the corresponding IOM and provides the details of the HART devices.
The PBHIOMB block allows you to create a HART channel during run time. For more information about configuring
the HART channel during run time, see the topic "Creating a new HART channel (PBHCHANNEL) when PBHIOMB
is loaded" on page 197.
Connection and status processing
When a PBHIOMB block is loaded, the connection status of the PBHIOMB with the PROFIBUS slave is
monitored and the connection status is displayed in the Main tab using the IOM status (IOMSTS) parameter.
The connection status of the PBHIOMB follows:
OK: HART Profile is read successfully.
Init (Hart Profile is not read): HART profile is not read.
