ControlLogix Module Operation Chapter 3
Input Modules in a Local
Chassis
When a module resides in the same chassis as the owner-controller, the following
configuration parameters affect how and when the input module multicasts data:
• Real-time sample
• Requested packet interval
Real Time Sample (RTS)
This configurable parameter instructs the module to perform the following
operations:
• Scan all of its input channels and store the data into on-board memory.
• Multicast the updated channel data (as well as other status data) to the
backplane of the local chassis.
IMPORTANT
The real time sample value is set during the initial configuration
using RSLogix 5000 software. This value can be adjusted
anytime.
