Schneider Electric AS-P840-000

The Schneider Electric ASP840000 984 Programmable Logic Controllers (PLCs) and 800-Series Input/Output are control systems used to manage and automate industrial processes. These systems consist of a PLC, which is connected to input and output modules on the plant floor. The input modules receive electrical signals from field sensing devices, such as sensors and switches, and convert them into a form that the PLC can process. The output modules receive electrical signals from the PLC and convert them into the necessary voltage or current levels to activate switching devices on the plant floor. These products are manufactured in France and are designed for Material handling, packaging, and textile machines usage. They come with a 2-year warranty from MRO Electric. We also carry I/O Modules from other manufacturers such as Modicon and ABB.

Control 

The PLC solves user logic at very fast, regular intervals, allowing for predictable control of the system. User logic is the custom program that determines what actions the system should take based on the data received from the input modules. The resulting changes in output states are then transmitted to the field, where they are implemented by the output modules.

All 984 PLCs have executive firmware, which is stored in non-volatile memory, and user logic, configuration data, and system status data are stored in volatile Random Access Memory (RAM). The RAM is backed up by batteries to maintain data integrity in the event of a power loss. The 984 PLCs can be programmed using ladder logic, a simple and intuitive programming technique, as well as special function blocks that provide additional functionality for more complex tasks.

Application

Input/output (I/O) systems are used to implement the application logic stored in the PLC on the plant floor. These systems consist of I/O modules that are wired to field sensing or switching devices and connected to the PLC via an I/O bus. The I/O subsystems can be located either locally, near the PLC, or remotely, at distances of up to 15,000 feet from the PLC. Local I/O communicates with the PLC through a housing backplane or local cables, while remote I/O uses a remote I/O interface installed at each I/O location.

Communication

The 984 PLCs also include built-in Modbus ports for communication with peripheral devices such as programming panels or host computers. Modbus is a RS 232-based protocol used for data acquisition, program editing, and archiving operations. In addition, the 984 PLCs have ports for supporting Modbus Plus, a peer-to-peer, token-bus network with a speed of one megabit per second, as well as ASCII communications.

The Modicon 984 PLC family offers a wide range of functionality and physical characteristics, allowing users to choose the product that best fits their specific needs. These PLCs are designed to be compatible with each other, but they vary in terms of their processing speed, memory capacity, and the number and type of I/O points. They are also available in different physical form factors, including rack-mounted, panel-mounted, and modular configurations.

In conclusion, the Schneider Electric ASP840000 984 Programmable Logic Controllers and 800-Series Input/Output are control systems used to automate and manage industrial processes. They consist of a PLC connected to input and output modules on the plant floor and can be programmed using ladder logic and special function blocks. These PLCs also have built-in communication ports for connecting to peripheral devices and support a range of functionality and physical characteristics to meet the needs of different applications.
