Overview
FLEX I/O is a small, modular I/O system for distributed applications that performs all of the functions of rack-based I/O. The FLEX I/O system contains the following components shown below:
adapter/power supply - powers the internal logic for as many as eight I/O modules
terminal base - contains a terminal strip to terminate wiring for two- or three-wire devices
I/O module - contains the bus interface and circuitry needed to perform specific functions related to your application
How FLEX I/O Mudules Communicate with Programmable Controllers
Data transfer to and from the remote I/O adapter/power supply and discrete I/O modules occurs every flexbus scan. This provides the controller with updated data. The remote I/O adapter/power supply transfers data to the analog I/O module (block transfer write) and from the analog I/O module (block transfer read) using BTW and BTR instructions in your ladder diagram program. These instructions let the adapter obtain input values and status from the I/O module, and let you send output values to establish the module's mode of operation.
The 1794-ASB series E adapter supports 5 different modes of addressing: standard, compact, complementary, standard-32 and complementary-32.
