Example
The following gure shows after how many module cycles it takes for the smoothed analog value
to approach 100 % in the case of a step response, depending on the set smoothing. This
specication is valid for all signal changes at the analog input.

Properties
The analog electronic modules 4 AI I 2WIRE HART, 4 AI I 4WIRE HART and 4 AO I HART support
up to four IEEE variables.
In the process image input (PII), a maximum of 20 bytes per module are available for the IEEE
variables. For the four IEEE variables, there are thus four blocks of 5 bytes each within the PII.
Requirements
The HART eld device must support the parameterized number of the IEEE variables.
