Getting Started

1336 FORCE — 5.9 August 1995

Step 1 — Initialize the Function Blocks

Initialize the function block BRAM to clear the current function
block application.

1. Toggle bit I:00/00 to indicate the block transfer.

2. Verify that the initialization was successful.

3. If N57:101 = 0F02

hex

(Block Transfer Read Data), there are no

errors.

Words N57:0 – N57:3 will be sent to the drive. Values are displayed in
hexadecimal format.

Step 2 — Download and Compile the Program

Thirty-two events can be downloaded in each block transfer. Because
this example consists of only (4) events, only (1) block transfer
routine is required to download the execution list.

1. Type the data shown in the table below into addresses N57:0 —

N57:9. The Block Transfer Write Data specifies a download
operation and contains the events in the execution list. Values are
displayed in hexadecimal format.

Words N57:0 – N57:5 are the Block Transfer Header Information

Words N57:6 – N57:9 are the Execution List

2. Toggle bit I:00/00 to initiate the block transfer routine which

downloads block transfer data and the execution list.

3. Verify that the write was successful. If N57:101 = 0F03

hex

(Block

Transfer Read data), there are no errors.
