Examples for the configuration of PI/ PO data
The PI data word 2 is to be assigned to the actual percentage (index = 6054
hex
).
Procedure:
1. Data type derived from the code table
^ 5.6-42.
– The data type of the parameter actual percentage value is I16, i.e. it is a word parameter (16 bit). The code
table for the parameter ”Process input data description structure“ (index = 6000
hex
) shows that the PI data
word 2 is to be entered under subindex 6 and 7 (word parameters).
– The subindex of the parameter ”PI data description“ (index = 6000
hex
) can be written with the PCP service
”Write“ (see
^ 5.6-49).
2. Enter the index of the parameter ”Actual percentage“: Write (index = 6000
hex
, subindex = 6
hex
, value = 6054
hex
)
3. Enter the subindex of the parameter ”Actual percentage“: Write (index = 6000
hex
subindex = 7
hex
, value = 0
hex
)
)
)
)
)
Note!
The index must be changed to zero to change a subindex.
You can then change the subindex before the index.
