(Words 20 – 23) Remote PLC - IP Address:

Words 20–23 specify the four integers, one integer

per word, of the dotted-decimal IP address of the remote PLC to be accessed.

(Words 24–27) Remote PLC - Program Name:

Words 24–27 specify the case-sensitive, zero-

terminated and padded program name (also called task name, which can be found through the
PROG Station Manager command on the server Ethernet Interface) to be used with access to
remote %P or %L memory. These words are required only for access to such memory and will be
ignored if the Memory Type field is not %P or %L. See Note below.

(Words 28–31) Remote PLC - Program Block Name:

Words 28–31 specify the case-sensitive,

zero-terminated and padded program block name (which can be found in the program block
declaration in the server ladder program) to be used with access to remote %L memory. These
words are required only for access to such memory and will be ignored if the Memory Type field is
not %P or %L.

Note

The Program Name (Words 24–27) and Program Block Name (Words
28–31) must have each pair of ASCII characters reversed within the PLC
memory. For example, the name “MARY” (“M” = 4DH, “A” = 41H,
“R” = 52H, “Y” = 59H) would have 414DH in the first word and 5952H in the
second word.
