System Limits - GE RX3i PROFINET User Manual

Chapter 1. Introduction

System Limits

1.6
I/O Controllers will have limitations on the system they support. One of these limits is the number of
PROFINET submodules supported. In the RX3i PNS rack, each power supply or I/O module is represented
by one PROFINET submodule. The RX3i PNS uses four to six submodules:
• two submodules for basic operation of the PNS module
• two built-in port submodules that are always configured
• up to two additional port submodules, one for each optional Ethernet port configured
Other limitations, such as the configuration and I/O sizes, are specific to the configuration options chosen.
Note that not every combination of options is supported in every system.
If the configuration uses all slots in every device with a large device count, the memory of the I/O
Controller system will be a limiting resource.
