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.
