Siemens SIMATIC S7-400 S7-400 PLC is used in high-end performance range of programmable controllers. SIMATIC S7-400PLC main features are: high processing speed, powerful performance and excellent communication CPU resource margin. Powerful PLC, applicable to the field of high-performance control solutions to meet the most complex tasks require functional classification of the CPU as well as the full range of templates, can always find the best solution for distributed systems and expand their communications capabilities automate tasks very simple, consisting of the system flexible and comfortable user-friendly, simple operation, fan-free design with the expansion of applications, system expansion without any problems S7-400 PLC modular product features fanless design, durable and reliable, and can choose more species level (functional escalation) of the CPU, and with a variety of common functions of a template, which enables the user to a different combination of proprietary systems as needed. When the control system, scale, or upgrade, as long as appropriate to add some templates, it will cause the system to upgrade and fully meet their needs. Applications SIMATIC S7-400 is used in high-end performance range of programmable controllers. The modular and fanless design, rugged, easy to expand and extensive communications capabilities, distributed architecture and user-friendly operation makes SIMATIC S7-400 easy to become middle and high performance control field preferred ideal solution. SIMATIC S7-400 applications include: general mechanical engineering, automotive, warehouse, machine tool, process control and instrumentation control technology, textile machinery, packaging machinery, control equipment, special machinery features multiple levels of escalation CPU, with various types of user-friendly features of the full-function modules, allowing users to constitute the best solution to meet the requirements of automated tasks. When the control task becomes more complex, the control system at any time can escalate, rather than too much to add additional templates. Product Features High-speed instruction processing, user-friendly set of parameters, password protection, system functions, user-friendly operator control and monitoring functions (HMI) has been integrated in SIMATIC operating system, CPU and self-diagnostic function testing intelligent diagnostic system continuously monitoring system functions and record special events and system errors, the mode selection switch technology highlights computing and communications by improving performance, increase your productivity by improving working memory, such as built-in load memory, FC, FB, DB number of blocks, you can make its wider application data block function block unified digital numbers can easily restore the factory settings of the serial number of the card reading function through the factory reset function (Factory Reset function), to better protect your proprietary technology SFC 109 "PROTECT" additional write-protect selected for firmware upgrades via the network, maintenance is very simple for the content loaded via SFC78 monitor can be made dynamically in response to the information source bottleneck by CP443-1 Adv.EX41 (Entry ID: 24020919) open Ethernet communication (Iso-on-TCP), it has a flexible integration options to optimize the PROFINET-IO CP connection Entry ID: 24020919 compared with V4 CPU, reducing the backup current
