Schneider Electric PC-E984-685 Overview

Modicon 984 Programmable Controller PCE984685

The Modicon 984 Programmable Controller PCE984685 is manufactured by Schneider Electric and is a part of the 984 Programmable Controllers series. 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.

Performance and Capacity Characteristics

The 984 Programmable Controller model 984-685 is a device designed for slot mount. It has a logic-solve speed of 2.0 milliseconds per kiloword and is equipped with a 16-bit CPU. The user logic size can be configured as either 8K or 16K. The controller also has 4096 RAM state registers and 2048 mixed-state RAM discrete inputs. The maximum number of I/O bits per drop is 512 for both input and output, and the maximum number of I/O bits per system is 16384 for both input and output. The total number of discrete I/O is 2048, which can be any mix of inputs and outputs.

Design

The 984 programmable controller is a PLC specifically designed for real-time control in industrial and manufacturing settings. With digital processing capabilities, it monitors the status of field devices through input modules, executes a user-defined logic program through its CPU, and then controls field device activity by sending signals to its output modules. This combination of input monitoring, program execution, and output control enables the 984 programmable controllers to perform a wide range of control tasks in real time.

Compatibility

The 984 controller line offers exceptional compatibility, a key benefit of its design approach. Regardless of their computational power, performance specifications, or hardware design, all 984 controllers share a consistent architecture. This ensures that the 984 instruction set, which defines the functional capabilities of the controller and is stored in the system firmware's executive PROM, contains common logic functions across all 984s. As a result, control logic created on a high-performance unit such as the 984-685 or 984B can be transferred to a smaller controller like the 984-145, as long as it has sufficient memory. Additionally, logic created on a smaller controller can be easily adapted to a larger unit. As your application grows, you can upgrade your controller hardware without having to rewrite your existing control logic.

The Modicon 984 group of programmable controllers offers a diverse selection of compact, mid-sized, and high-performance CPUs. Despite differences in hardware, all 984 controllers use a unified processing architecture and are programmed using ladder logic, a graphical language that resembles relay symbols. They also share a common set of instructions covering calculation, data transfer, matrix operations, and special applications. Modicon provides multiple networking options, enabling interconnection between multiple controllers and other devices to enhance control and data exchange in applications.

The design approach for 984 controllers enables decision-making based on controller capabilities, such as the quantity of discrete and analog/register points for programming applications, the number of I/O drops supported, and the efficiency, represented by the speed at which it processes logic and updates I/O modules, as well as its resistance to environmental factors.
