IMPORTANT
A ControlLogix high-speed analog I/O module’s performance behavior varies
depending upon whether it operates in the local chassis or in a remote chassis.
Module performance is limited in a remote chassis. The network cannot
effectively accommodate the fastest module update rates because the size of
the data broadcast requires a large portion of the network’s bandwidth. For
maximum module performance, we recommend you use it in a local chassis.
This chapter describes how the ControlLogix high-speed analog I/O module
operates in a local chassis. For more information on how the module operates
in a remote chassis, see
