This module supports Modicon Modbus protocol (serial port), Modbus/TCP protocol (Ethernet), and Bently Nevada proprietary protocol, and can communicate with 3500 Rack Configuration Software and data acquisition software via Ethernet.

The 3500/92 provides RJ45 10BASE-T Ethernet interface, supports star network topology, and includes a configurable Modbus register tool, replacing the main Modbus register function of the early 3500/90.

It is widely used in scenarios where the 3500 monitoring system needs to be integrated with DCS, PLC, or SCADA systems to achieve remote monitoring and centralized management of rotating equipment status.

In 1968, General Motors' hydraulic department established the first standard for programmable controllers, with the aim of eliminating complex and expensive relay control systems. This design specification requires solid-state systems and computer technology, and requires the ability to survive in industrial environments, be easily programmable, and be reusable. In 1969, the first PLC was born. At that time, it was called Programmable Controller, abbreviated as PC. As the first generation PLC was designed to replace relays, ladder diagram language was adopted as the programming method, forming the programming standard for factories. These early controllers met the initial requirements and opened the door to the development of new control technologies. In a short period of time, PLC rapidly expanded to multiple industries such as food, beverage, metal processing, manufacturing, and papermaking. PLCs are usually classified into micro PLCs, small PLCs, medium PLCs, large PLCs, PC plug-in PLCs, and PC compatible PLCs based on the size of the I/O points carried by the CPU. The classification standards for various scales are shown in the attached table. A typical PLC typically includes a CPU module, a power module, and some input/output modules, which are plugged into a backplane. If the configuration is increased, it may include an operator interface, monitoring computer, communication module, software, and some optional special function modules. Programmable controllers are not only easy to install, take up less space, consume less energy, and come with diagnostic indicators to help diagnose faults, but can also be reused in other projects. Although the functions of PLC, such as operating speed, interface types, and data processing capabilities, have been greatly improved, PLC has always maintained its original design principle, which is the principle of simplicity first.

The Development of PLC

The technology of PLCs has been continuously developing since its inception. These developments have not only improved the design of PLCs, but also changed the design philosophy of control systems. In the past, PLCs were suitable for discrete process control, such as switches and sequential action execution. However, with the increasing power of PLCs, they have also begun to enter the field of process automation.

Adopting new advanced microprocessors and electronic technology to achieve fast scanning time; ·A small, low-cost PLC that can replace four to ten relays; ·High density I/O system provides space saving interfaces at low cost; ·The intelligent I/O interface based on microprocessors extends distributed control capabilities, with typical interfaces such as PID, network, CAN bus, fieldbus, ASCII communication, positioning, host communication modules, and language modules (such as BASIC, PASCAL); ·Improvement in the structural design of input/output modules and terminals to make them more integrated; ·Special interfaces allow certain devices to be directly connected to the controller, such as thermocouples, thermistors, stress measurements, fast response pulses, etc; ·External devices have improved operator interface technology, and system documentation has become a standard feature of PLCs. The above hardware improvements have led to the enrichment and development of PLC product lines, ranging from the smallest micro PLC with only 10 I/O points to large PLCs that can reach 8000 points. These product series can form a local area network and connect to office networks using ordinary I/O systems and programmed external devices. The concept of the entire PLC product line is a very cost-effective control system concept for users.

The software development of PLC is similar to the hardware development, and the software of PLC has also made great progress, greatly strengthening the functions of PLC: PLC has introduced object-oriented programming tools and formed multiple languages according to the IEC 61131-3 standard of the International Electrotechnical Commission; ·Small PLCs also provide powerful programming instructions and thus extend their application areas; ·High level languages such as BASIC and C can already be implemented in certain controller modules, providing greater programming flexibility when communicating with external devices and processing data; ·Advanced functional block instructions can be implemented in ladder diagram logic, allowing users to implement complex software functions using simple programming methods; ·The diagnostic and error detection functions have expanded from simple system controller fault diagnosis to process and equipment diagnosis of the controlled machines and devices; ·Floating point arithmetic can perform complex calculations involved in metrology, balance, and statistics in control applications; ·The data processing instructions have been simplified and improved, enabling complex control and data acquisition and processing functions involving large amounts of data storage, tracking, and access. Although PLCs are much more complex than before, they still maintain surprising simplicity. For operators, today's high-performance PLCs are as easy to operate as PLCs were 30 years ago, and even simpler.
