8.5.3 About auto-discovery of HART devices

The PBHIOMB block enables you to find the HART devices that are connected to the HART IO module. The
auto-discovery of the HART devices can be performed only when the loaded PBHIOMB have some channels
(PBHCHANNEL) that are not configured.
Attention
If all the channels in the PBHIOMB are configured, then the auto-discovery of HART devices is not possible.
You can use the Find HART Devices (FINDHDEVICES) parameter to discover the HART devices that are
connected to the HART IO module. The following figure displays the PBHIOMB configuration form when the
auto-discovery of HART devices is enabled.
