Parameters P9.09~P9.24 and P9.69~P9.84
Block Transfer allows parameters from many different Parameter Groups to be consolidated into
one Modbus communication message. This can greatly simplify PLC programming and reduce
network traffic. Unlike previous GS drives*, the GS4 has two sets of Block Transfer Parameters:
A) New Pointer Parameters P9.69~P9.84 (where you enter the addresses that you want to
consolidate)
B) Data Location Parameters P9.09~P9.24 (where you push data into, or pull data out of)

Example:
You want to consolidate the parameters Multi-Speed 15 (P5.15), Skip Frequency 3 Lower Limit
(P1.24), and Circulation Time (P10.02). Enter the following values into P9.69, P9.70, and P9.71:
Address Pointers
Data Locations
(to Push Data to, or Pull Data from)
Block Transfer 1 P9�69 = 515 (points to P5�15) P9�09
Block Transfer 2 P9�70 = 124 (points to P1�24) P9�10
Block Transfer 3 P9�71 = 1002 (points to P10�02) P9�11
The Address Pointers use xxyy format, where: • xx = Parameter Group# and
• yy = Parameter# in that group.
All of the data is now in consecutive order so that you can write one Modbus message to P9.09
with a length of three registers, and it will change P5.15, P1.24, and P10.02. Or you can use one
Modbus Read message that will collect all three parameters at once. Without Block Transfer,
reading or writing these three parameters would require three separate communication
commands from an external PLC.
* Previous GS Drives had only one set of parameters for Block Transfer, and the Pointer Addresses had
to be manually entered into the keypad. Only then would any read or write into that Block Transfer
address actually be linked to the desired data. Unfortunately, this meant that you would have to
manually enter Block Transfer addresses via the keypad for any new drive. With the GS4 method, the
Pointer Addresses are in separate parameters. Thus, the complete configuration can be downloaded
via software (no keypad entry necessary).
