From Address

0 to highest Status Data address

This field specifies the internal database register to be copied from. This address
can range from the Data area as well as the Status Data Area of the product

To Address

0 to 3999

The destination for the copy is always going to be the Register Data area.

Register Count

1 to 100

This parameter specifies the number of registers to be copied.

Swap Code

0,1,2,3

You may need to swap the order of the bytes in the registers during the copy
process in order to change from 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

0

None - No Change is made in the byte ordering (1234 = 1234)

1

Words - The words are swapped (1234=3412)

2

Words & Bytes - The words are swapped then the bytes in each word are
swapped (1234=4321)

3

Bytes - The bytes in each word are swapped (1234=2143)


Delay Preset

Copies one portion of the database or virtual database to a user specified
location in the database. The Delay Preset represents the scan count of the
program between each copy operation. The copy operations should not all
happen at the same time, otherwise the process could delay the scan. For
example, you should not set all values to a delay preset of 1001. Instead, use
values such as 1000, 1001 and 1002, or you can use the preset values in the
sample configuration file. This will keep the copies from happening concurrently.

Tip:

Use the [V] command in the Configuration/Debug Menu (page 77) to

view the status of the Program Scan Counter. Repeat the command to see the
value change.
