You can check out our previous blog post on the 140ACI03000 datasheet, wiring diagram, and manual here for more information.
140ACI03000 Wiring Configuration Features:
The Modicon 140ACI03000 configuration processor easily plugs into the Quantum backplane. The fiber optic cable connects the two Hot Standby processors to provide a high speed communication path between the two controllers. No additional intermediate supervisor is required. This minimizes hardware and reduces panel space requirements. Simple installation makes the Quantum Hot Standby option processor an easy addition to any control system setup.
The new 140ACI03000 scaling configuration provides two methods for system configuration. The Quantum Hot Standby system also delivers the power of user configurable State RAM transfers from the primary to standby controllers. This new option provides all of the power of the function block solution and more. As few as 16 inputs, 16 outputs, one input register, and one output/holding register or as many as 64k, in the Quantum 486 controllers, can be configured for transfer in one or multiple scans. This option provides true separation of system configuration and control programming.
Users that are comfortable with the 984/800 series hot standby solution can opt for the single function block. This option provides all of the programming necessary to perform the hot standby function. By simply entering and energizing the function block in each controller, the default settings will affect a secure and reliable control system.
Should the user select to implement some optional hot standby functionality, all user options are triggered by inputs or register bits in the function block. Using Modsoft 2.3 DX Zoom capability all register bit functions are described in easy to understand terms that eliminate guess work.
