Chapter 9Remote I/O Scanner Datagrams

This chapter lists datagrams that can be sent to a Remote I/O Scanner module, and

shows the format of the Read Map, Write Map, and Read Map Reply Datagrams.

Datagrams cannot be sent to individual I/O modules in a remote drop.

It also shows the format of Report Fault datagrams that are sent by the Remote I/O

Scanner.

For Additional Information, Also See:

The bus controller User’s Manual for the PLC or computer, which explains

programming to send datagrams.

The Genius I/O System and Communications Manual, which describes additional

datagrams and data formats.
