The “Path” in the communication tab of the block transfer message write is the

name of the DH+/RIO scanner module. The “Module Address” sets the channel

of the DH+/RIO scanner used, and the rack, group and slot of the

20-COMM-R.

For the block transfer message read, the destination tag

RIO_BT_Response_Data must be an array of 20, 30, or 60 INTs (depending on

how much data the user is receiving). This tag cannot be DINT.

The communication tab of the block transfer message read is setup the same as

the block transfer message write.

The block transfer messages on RIO are limited to 16-bit integers. Therefore, 32

bit parameters are split into 16 bit integers in the block transfer request and

response data. In order to write or read floating point or 32-bit integers the COP

(copy) instruction must be utilized. The copy instruction in ControlLogix

performs a bitwise copy. Set the length of the copy instruction to a value

appropriate for the destination data type.
