Introduction

You can broadcast messages over a serial port connection from a master controller to all of its slave controllers by using several After you have selected your I/O modules, you need to validate the system you want to design. Before you begin to place your I/O modules, consider that the minimum backplane RPI increases as you add modules. Also, the I/O modules must be distributed so that the current consumed from the left or right side of the power supply never exceeds 2.0 A at 5V DC or 1.0 A at 24V DC. Estimate Requested Packet Interval The requested packet interval (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. The effective scan frequency for any individual module is still impacted by the other modules in the system and those modules’ RPI settings. The following table provides relative scanning durations for various types of modules. This information should be taken into account when setting an individual module’s RPI in order to achieve the desired effective scan frequency for any module in the system.
