Domestic PLC gone from imitation to independent research and development stage, software and hardware are showing more and more independent product, especially in the field of small PLC emerged in many plc analog output module excellent companies. Nanda proud Tinto PLC as a few of the large manufacturers to ensure product reliability, based on the products in order to strengthen the integration advantages, through custom development and localization services to build their core strengths, serving the industrial users.
From PLC product line perspective, Nanda proud extension NA400 and NA200 two existing series. NA400 series PLC is mainly used in all kinds of engineering automation, especially in the petrochemical industry, coal mining, rail transportation, water conservancy and hydropower, building automation, environmental protection, municipal and other areas; NA200 series PLC, mainly in the field of automation engineering with NA400 series of product applications, focusing on logic control of packaging machinery, food pharmaceutical machinery, lifting machinery, engineering machinery, textile machinery and other fields.
In NA400 series PLC products, CPU401-0501 product is its representative products, which in addition to all NA400 series PLC as providing safe and reliable operation of the system to all intelligent I / O design and a range of security, reliability, designed for protection, but also with hardware redundancy. In a redundant Plc high speed counting modules function implementation, to achieve a complete scan of all data exchange, redundant communication rates up to 100 Mbps, users do not need any programming work and hot standby module, you can achieve redundancy, while hot-swappable replacement module can be flexibly applied to a single chassis and dual redundant system chassis redundant systems.
Analog inputs, (meaning the module is to convert your voltage or current value to digital, then you can calculate the slope of the current form of the temperature or pressure.) If you ask to read the temperature or pressure values that you must bring the analog sensor output and analog output.

PLC typical boot process
input Refreshrerun user programsand then output refreshthen enter refresh then run user programs and then output the brush never stop the cycle repeated manner. With PLC control is clearly possible. Because: With input refresh, enter information analog input plc can be obtained by monitoring the input circuit stores the PLC input mapping area; by running the user program, the output mapping area will get the information transformed; then by the output refresh, the output latch will reflect the state of the output mapping area, and generates a corresponding output via the output circuit. Also, because this process is never-ending cycle of repeatedly plc ethernet module engaged in ground, so the output always reflects the change in input. The only response time, a slight lag. Of course, this lag should not be too large, otherwise, control achieved not so timely, it lost control of meaning. To this end, the working speed of the PLC to be fast. Fast instruction execution time is short, is the basis for control of the PLC. In fact, its speed is very fast, execute a command, and more a few microseconds, tens of microseconds, only a few tenths less, or 0.0 microseconds. And this rate still increasing in.
