You can install your input module in any system that uses Allen-Bradley
programmable controllers with block transfer capability and the 1771 I/O
structure.
Contact your nearest Allen-Bradley office for more information about your
programmable controllers.
The 1771-IFE module can be used with any 1771 I/O chassis.
Communication between the discrete analog module and the processor is
bidirectional; the processor block-transfers output data through the output
image table to the module and block-transfers input data from the module
through the input image table. The module also requires an area in the data
table to store the read block transfer data and write block transfer data. I/O
image table use is an important factor in module placement and addressing
selection. Compatibility and data table use is listed in Table P.A.
