Communicate with a PanelView™ Standard Terminal 9-5
Use a Word/Bit Format for Each Tag
Each I/O slave tag requires a specific address in the corresponding
assembly instance. A tag address follows this format:
For Integers, Skip Every Other Word
Logix5000 controllers use 32-bit integers (DINTs). To make your
programming easier, lay out your PanelView tags as follows:
Type :Word /Bit
= Optional
Where: Is:
Type Type of tag
If the tag is a: Then use:
write tag (sends input data to the controller) I
read tag (gets output data from the controller) O
Word Specific 16-bit word within the assembly
Bit Specific bit within Word (0 - 15)
Word
1. For bit-level tags, set aside an even
number of words.
015…0
115…0
215…0
315…0
2. For each integer, set aside 2 words.
Start each integer on an even word.
This lets each integer map to its
own element in the
scanner/controller.
4 Address of an integer value.
5
Do not address this word. (Leave it unused.)
6 Address of an integer value.
7
Do not address this word. (Leave it unused.)
