Concept for HIQuad X

HIQuad X is an innovative, high-performance automation system that is based on the existing HIQuad system. SILworX, HIMA's tried and tested programming tool, is used for programming, configuring, monitoring, operating and documenting HIQuad X. All HIMA programmable systems are thus future-proof and operated with just one programming tool. Additionally, HIQuad X supports already existing HIQuad I/O modules.

The H51X Mono System

Thanks to the use of safety-related modules (I/O modules, the I/O processing module and a processor module), the HIQuad H51X system can ensure safety-related signal processing in accordance with SIL 3 already when operating in a mono structure

The input modules of the HIQuad H51X system safely record the values measured by sensors. Data is exchanged with the processor module via the I/O processing module. The measured values are cyclically queried by the processor module and processed by the user program. The user program's results are sent to the I/O processing module, which writes them to the output modules. The output modules thus control the field level, e.g., the actuators. During mono operation, the signal is forwarded by the processor module in slot 8 via system bus A.

Shows the example of an H51X mono system with system bus A. Up to 16 extension racks can be connected to the system bus in any UP loop, DOWN loop, or UP and DOWN loop. The extension racks are interconnected with system bus A via the I/O processing module, see the F-IOP 01 manual (HI 803 219 E).

If the system bus connection is interrupted in a mono system, all I/O modules located after the interruption point are no longer available. After the interruption point, all output modules enter the safety-related, de-energized state. As for the input modules, the failsafe initial values are processed in the respective processor module.
