Performance Features

Storage Capacity and Functions: The memory module has a storage capacity of 256k bytes and is capable of storing a large amount of programs and data. As an EPROM, it is mainly used to store fixed and infrequently changed programmes and important data, such as the system's bootloader, key configuration parameters, control algorithms, etc., to provide reliable storage support for the stable operation of the system.

Data reading speed: Although the specific reading speed is not explicitly given, in general, this kind of industrial-grade EPROM memory module can meet the real-time data reading requirements of the control system and ensure that the system can quickly and accurately obtain the required data during operation, thus supporting the efficient operation of the system.

Compatibility: The PCM02 has good compatibility with other components of the H&B Contronic series, and can work seamlessly with CPU modules, input and output modules and other devices of the series to build a complete industrial automation control system, ensuring that all parts of the system can work together to achieve precise control and monitoring of the production process.

Reliability and Stability: Adopting high quality electronic components and advanced manufacturing process, it has high reliability and stability. It can operate stably for a long time in harsh industrial environments, resisting the influence of electromagnetic interference, temperature changes, humidity changes and other unfavourable factors, thus ensuring the normal operation of the system and reducing the system downtime caused by hardware failure.

Application Fields

Industrial automation control system: Widely used in various industrial automation production lines, such as automobile manufacturing, machinery processing, food and beverage production. In the automobile production line, it can be used to store the control programme of the robot, welding parameters, quality inspection standards and other data; in machining, it can store the machining programme of the numerical control equipment, tool compensation parameters, etc., to ensure the high efficiency, stability and reliable quality of the production process.

Process control field: It has important applications in chemical, pharmaceutical, electric power and other process control industries. Take chemical production as an example, it can store the temperature control procedure of the reactor, pressure adjustment parameters, material flow rate setting value, etc. Through the collaborative work with sensors, actuators and other equipment, it can achieve precise control of the chemical production process to ensure product quality and production safety.

Intelligent Building System: In the automated management of intelligent buildings, such as building automation system, security monitoring system also plays an important role. For example, in the building automation system, it can store the control strategy of air conditioning system, the schedule of lighting system, the operation parameters of lift system, etc., so as to realise the intelligent management of all kinds of equipments in the building, to improve the efficiency of energy use, and to reduce the operation cost.

And the return sequence can be summarized in  the following steps: 

• The Line 1 will start the normal functioning 

• Change-over switch stays in position II 

• An anomaly occurs on the Line 2 (LN2) 

• Change-over switch stays in position II 

• Change-over switch can be transferred  manually back to position I
