S7-400H

As a professional manufacturer, Yueyang Tongtu offers you Siemens S7-400H. This is an "automated control system composed of two completely independent central processing units (cpus), power supplies and communication modules, which are connected through synchronous optical fibers to achieve hot standby redundancy." Its core value lies in the fact that it has completely solved the major problem of "single point of failure" in industrial control. During operation, two sets of cpus work simultaneously, one as the Master and the other as the Slave, with real-time data synchronization. Once any failure occurs in the main CPU (power supply, module, software), the backup CPU will seamlessly take over all control tasks within milliseconds. The entire process is completely imperceptible to external devices without any interruption.

Feature

The first impression that this Siemens S7-400H system gives is "redundancy" and "robustness". Its racks usually come in pairs, and the module configurations inside are almost mirror images, giving people a sense of double insurance. Each module is a plug-and-pull design, featuring sturdy metal rails and locking mechanisms. Several special optical fiber synchronization cables are connected between the racks, which is the "lifeline" for it to achieve heartbeat synchronization. This "fault-tolerant design" that is reflected from the hardware architecture is a direct manifestation of it as a highly reliable controller.

Specification

Freight transportation advantages

For this core control system that is extremely sensitive to static electricity and shock and is very expensive, our packaging standard is "military-grade anti-static and anti-shock packaging". Our Yueyang Tongtu Company will first seal each module in an original factory anti-static bag, and then place it in a customized, high-density foam model to ensure that the module is firmly fixed inside the box. The entire rack or complete system will be packed in wooden crates and may be transported by air to shorten the transportation time, ensuring that this "guardian of safety" can reach your control room in the best condition.
