1-12 About the FLEX Ex HART Analog Modules
Host_Group
The FLEX Ex HART modules have two message-access ports into
them allowing two systems to gather information from the module
concurrently.
The HART_Groups are numbered either 1 or 2. If there are no other
systems accessing the FLEX Ex Hart I/O module, that is, an asset
management system, then select the first HART_Group by setting this
value to 1. The data type is SINT.
HART Initialize Channel Tags
The channel member of the HART_Target tag is a decimal number that
indicates which channel is the target. The channels’ member of the
HART_initialize tag consists of eight one bit flags.
IMPORTANT
If multiple owners access or control the same FLEX Ex HART I/O
module and field device, they must maintain identical
configurations.
IMPORTANT
To make the HART_initialize routine run effectively, only enable
channels with active HART field devices.
