Set 1769 I/O Module Configuration
The length of this command is determined by the size of the
configuration file for the 1769 I/O module we will configure. In this
case, from the previous section, we read the configuration size for the
1769-OF2 as 8 words, the length of this command is 14 words. Refer
to the Ladder Logic Example Program on page B-30 to learn how to
copy this command to the M0 file of the 1747-SDN as well as how to
copy the reply from the scanner’s M1 file.
The scanner sets an input image bit (I:s/15, where s is the slot number
of the 1747-SDN) to indicate to the user program that a reply is ready.
Following each command reply, the user program must move a
command value (using a MOV instruction) of 4 hexadecimal to the
appropriate M0 file word to clear the previous reply from its buffer,
making it ready for the next command.
The following illustrates the Set 1769 Module Configuration command
for a 1769-OF2 module and the command reply:
