Processor Module (Yokogawa CP401)

Figure 5 shows the dual redundant configuration of the processor module. The dual-redundant processor module uses a field-proven "pairing and standby" method. Each processor module contains two MPUs, where the MPU performs the same control calculations, and the verifier cross-checks the calculation results to detect transient errors. With the dual redundancy of the processor module, the transfer of control rights and the continuation of control can be carried out when the system fails without any instantaneous shutdown, thus achieving high system availability.

Figure 6 shows the appearance of the processor module. The shape of the module has changed from a traditional card-like form to a modular form in which internal components are encapsulated in a molded case. For the internal hardware configuration, we reused the hardware assets, namely the industry-proven CENTUM CS3000 processor card (CP345) and SB bus interface card (SB301), and merged them into one module while maintaining software compatibility . As much as possible. Equipped with an industry-proven CP345 processor card using a microprocessor-verified microprocessor, this processor module can build a scalable system by using the same system software used in small and medium-sized factories and large factories. plant.

In order to install CP345 and SB301 on a single module (ie to achieve miniaturization), we are actively adopting programmable devices as large-scale integrated components in fine-pitch multi-pin ball grid arrays (BGA), chip capacitors and resistors in 1005 size Small components, and new basic technologies, including laminates for dense mounting of such components.

The processor module contains a battery pack to back up the main memory in the event of a power failure. However, considering environmental protection, the traditional nickel-cadmium batteries have been discarded and replaced by nickel-hydrogen batteries.
