232 Publication IASIMP-QS010B-EN-P - October 2009
Chapter 4 Add Additional Local I/O
Remember that RPI reflects how quickly the I/O modules can be scanned, not
how quickly a program can use the data. The requested RPI defines the
frequency at which the controller sends and receives all I/O data on the
backplane. Each module on the backplane can have its own individual RPI
setting.
Additional Resources
For more information about the expansion I/O module you are adding, see
your module’s installation instructions and user manual.
