Introduction

You can broadcast messages over a serial port connection from a master controllerto all of its slave controllers by using several After you have selected your I/O modules, you need to validate the system youwant to design. Before you begin to place your I/O modules, consider that theminimum backplane RPI increases as you add modules. Also, the I/O modulesmust be distributed so that the current consumed from the left or right side of thepower supply never exceeds 2.0 A at 5V DC or 1.0 A at 24V DC.Estimate Requested Packet IntervalThe requested packet interval (RPI) defines the frequency at which thecontroller sends and receives all I/O data on the backplane. Each module on thebackplane can have its own individual RPI setting.The effective scan frequency for any individual module is still impacted by theother modules in the system and those modules’ RPI settings. The following tableprovides relative scanning durations for various types of modules. Thisinformation should be taken into account when setting an individual module’sRPI in order to achieve the desired effective scan frequency for any module in thesystem.
