5.26.3 Register Count
1 to 100
This parameter specifies the number of registers to copy.
5.26.4 Swap Code
No Change, Word Swap, Word and Byte Swap, Byte Swap
You may need to swap the order of the bytes in the registers during the copy
process in order to change the alignment of bytes between dissimilar protocols.
This parameter is helpful when dealing with floating-point or other multi-register
values, as there is no standard method of storage of these data types in slave
devices.
The following table defines the values and their associated operations:
Swap Code
Description
No Swap No Change is made in the byte ordering (1234 = 1234)
Word Swap The words are swapped (1234=3412)
Word and
Byte Swap The words are swapped then the bytes in each word are swapped (1234=4321)
Bytes The bytes in each word are swapped (1234=2143)
5.26.5 Delay Preset
This parameter sets an interval for each Data Map copy operation. The value you
put for the Delay Preset is not a fixed amount of time. It is the number of firmware
scans that must transpire between copy operations.
The firmware scan cycle can take a variable amount of time. Each firmware scan
can take from 1 to several milliseconds to complete. Therefore, Data Map copy
operations cannot be expected to happen at regular intervals.
