Assigning The Channel And Ieee Tag - Siemens SIMATIC ET 200iSP Operating Instructions Manual

Analog electronic modules
13.12 Parameter description of the analog electronic modules
The stronger the smoothing, the more stable the smoothed analog value and the longer it takes
until the smoothed analog signal is applied following a step response (refer to the following
example).
Example
The figure below shows the number of cycles a module requires to apply a close to 100%
analog value after a step response, based on the smoothing function settings. The figure
applies to all signal changes at the analog input.

Assigning the channel and IEEE tag

Properties
Analog electronic modules 4 AI I 2WIRE/HART, 4 AI I 4WIRE/ HART and 4 AO I HART support
up to four IEEE tags.
The process input image (PII) provides up to 20 bytes per module for the IEEE tags. Thus,
four blocks of 5 bytes each are available for the four IEEE tags within the PII.
Prerequisites
The HART field device must support the assigned number of IEEE tags.
