B-8 Explicit Messaging Application Examples

The following screen is the Communications tab for the MSG

instruction above.

The reply to this message, when successful, will be one word of data

containing the word length of the configuration file for the 1769 I/O

module to which the message was sent. This data will be stored in the

Logix5550 controller at the tag specified in the “Destination” field for

the message instruction.

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 (16 bytes). Six words contain the configuration

data, while the last two words must be set to 0. The length, however,

must be 16 bytes.
