System Limits - GE GFK-2892F User Manual

Chapter 1. Introduction

1.9 System Limits

IO-Controllers have limitations on the size of the system they support. One of these limits is the number of
PROFINET sub-modules supported. The GCG001 uses four sub-modules: two for basic operation and two built-
in port sub-modules that are always configured. Each Genius device attached to a GCG001 uses one additional
sub-module.
Other limitations, such as the configuration and IO 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 Genius bus
slots with a corresponding large device count, the memory of the IO-Controller system will be a limiting
resource.
Refer to the PACSystems RX3i & RSTi-EP PROFINET I/O Controller Manual, GFK-2571, for actual limits in the
RX3i PROFINET Controller (PNC001) and the embedded PROFINET controllers.
Refer to the Genius I/O System and Communications User's Manual, GEK-90486-1 for information on how
much I/O, and which type of I/O, need to be allocated to Genius devices.
PME (v8.0 or later) takes into account both system limits and I/O allocation.
