3.5.4 HART Pass-through Handle Timeout
The Handle time out value allows the user to set how long the module will hold the reply
message for a HART Pass-through operation in its queue. If the time expires before the
reply has been retrieved using the “Query” message, the reply is removed from the queue
and the queue is now available for another Pass-through message.
Value Units: Seconds
Value Limits: 1 to 255 seconds.

Read Input
Data
The input data file contains module status information and analog input data for each of
the input channels. Analog input data is read for each channel, converted to a scaled
digital value, and stored in the input tags. The input tags for the IExCH are located under
the controller tags. The following examples describe the tag structure allocated by the
Generic Module profile and the AOP.
Generic Module Profile:
[Name of remote communication module]:e:x.Data[0 to 198]
e = IExCH slot number
x = Image Type (i.e. C, I, or O)
AOP (Add-On-Profile):
[Name of remote communication module]:e:x
e = IE4CH slot number
x = Image Type (i.e. C, I, or O)
Note: The AOP will provide a predefined tag structure for the input tags.
See example below.
