About the FLEX Ex HART Analog Modules 1-9
HART Target Tags
The HART_Target tag consists of four members:
• Path — HART_Target.Path
The Path specifies the direction the message follows to get to the
desired target node. The data type is string.
• Slot — HART_Target.Slot
The Slot indicates the specific place where the I/O module is attached
to the FLEX Ex adapter. The data type is SINT.
1 = the closest module to the adapter
8 = the module farthest from the adapter
0 = the adapter
• Channel
The Channel indicates which analog channel, 0 to 7, is desired. The data
type is SINT.
• 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 data type is SINT.
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.
IMPORTANT
If multiple owners access or control the same FLEX Ex HART I/O
module and field device, they must maintain identical
configurations.
