NOTE: These Block Transfer parameters can only be accessed through Modbus; not through the
Touchscreen Menu.
Block Transfer allows parameters from many different Parameter Groups to be consolidated
into one Modbus communication message. This procedure can greatly simplify PLC
programming and reduce network traffic. A maximum of 16 parameters can be grouped
together into one block. The sixteen (16) two-byte Block Transfer Address Pointer Registers
have 16 correlating four-byte Block Transfer Data Registers that correspond with the Pointer
registers. The Pointer registers act as the data conduits for each select address. Once set, the
addresses can be saved in non-volatile memory if required.
• Pointer Parameters P0�20~P0�35 are where to enter the addresses that you want to
consolidate�
• Data Location Parameters P0�40~P0�55 are locations to push data into, or to pull data out of�
The following table shows the relationship between the Transfer registers and Data registers:

The address registers can take any data type that can fit into four (4) bytes, so any address
that yields six (6) bytes of data (such as time) will be incomplete. For accessing data that is
more than four (4) bytes, that register should be read from or written to directly, rather than
by the Block Transfer method.
