Byte assignment of the process data
If a word parameter (16 bit) is assigned to the process data, the
parameter address (index, subindex) is entered in the first corresponding
byte. The second byte is not used and must have a 0. For double word
parameters (32 bit), 3 bytes are not used. The configuration can be
modified in common (subindex = 0) or only in parts.
To ensure the data consistency of the process output data (output data of
the master), the parameter "enable process output data" is necessary.
Example 1
−−−− Changing the process input data:
1. Assignment of the 2nd PCD word with the actual percentage (index = 6054 hex )
Write (index = 6000
hex
; subindex =6
hex
; value = 6054
hex
)
Write (index = 6000
hex
; subindex =7
hex
; value = 0
hex
) (may be omitted)
Example 2
−−−− Changing the process output data:
1. Inhibit process output data
Write (index = 6002
hex
; subindex =0
hex
; value = 0
hex
)
2. Assignment of the 2nd PCD word with nominal percentage (index = 6052
hex
)
Write (index = 6001
hex
; subindex =6
hex
; value = 6052
hex
)
Write (index = 6001
hex
; subindex =7
hex
; value = 0
hex
) (may be omitted)
3. Enable process output data
Write (index = 6002
hex
; subindex =0
hex
; value = FF
hex
)
