Configuring RSLogix 5000 Software to Access
Data on the 1757-ABRIO Module
Introduction This chapter describes:
the operating modes of the 1757-ABRIO module.
how to access data on the module from a ControlLogix
controller.
Modes of Operation There are four modes of operation for the module.
CONFIG
INACTIVE (Program)
ACTIVE (Run)
FORCED ACTIVE
The mode of the 1757-ABRIO module determines the RIO network
mode.
Modes related to RIO network operations:
INACTIVE (Program) mode, digital inputs continue to update
but digital outputs and block transfers do not.
ACTIVE (Run) mode, digital inputs and outputs update, and
block transfers update.
CONFIG Mode
The module is in CONFIG mode while AbRioCfg software downloads
a configuration. CONFIG mode is largely invisible to the user unless
the configuration being downloaded is large. After downloading, the
software returns the module to INACTIVE mode.
