Chapter 4 Using 1715 Analog I/O Module Features
Features Common to All
Analog I/O Modules
The features that are common to all 1715 and ControlLogix analog I/O modules
are listed in Table 22 . The features are described later in this section.
Removal and Insertion Under Power (RIUP)
All 1715 I/O modules can be inserted and removed from the chassis while power
is applied. This feature allows greater availability of the overall control system
because, while the module is being removed or inserted, there is no additional
disruption to the rest of the controlled process.
Module Fault Reporting
The 1715 analog I/O modules provide hardware and software indication when a
module fault has occurred. Each module has a status fault indicator and
the Logix Designer application graphically displays this fault and include a fault
message describing the nature of the fault. This feature lets you determine how
your module has been affected and what action must be taken to resume normal
operation.
