Step 3 — Write Node Values

One node value is downloaded in each block transfer routine. The
same block transfer routine is used in each download, but
information in the data file is changed for each node value that is
transferred. As shown below, the data in word N57:2 specifies the
block and node that is being written to, while word N57:3 specifies
the value that is being sent. Data is entered in hexadecimal format.

— Enter the 1st Value at the Function Block Node

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

downloads the node value.

3. Verify that the write was successful. If N57:101 = 0F01

(Block

Transfer Read data), there are no errors.
