Allen-Bradley 1771-IFF Fast Analog Input Module Electrodynamic Velocity Sensor Minimum Number of CF9s: 2Overview The 1771 IFF Series A module is compatible with any 1771 I O chassis. It facilitates bidirectional communication between the analog module and the processor. The processor sends block transfer output data to the module via the output image table and receives block transfer input data from the module through the input image table. Additionally, the module needs allocated space in the data table to store both read and write block transfer data.
