Product Introduction

hardware configuration

Application processor: SX processor is Motorola MPC860, 32-bit, 50MHz; The flash PROM is 6MB, used for SX, IOX, and control application

storage, with CRC protection; DRAM is 16MB, used for SX control application execution and program, as well as SOE data byte parity check;

The NVRAM is 8KB and is used as a holding variable for CRC protection.

Input/output processor: IOX processor is Motorola MPC860, 32-bit, 50MHz; DRAM is 16MB, used for IOX byte parity check; The shared memory

is 128KB, used for communication with SX byte parity check; The diagnostic bus is 2Mbps HDLC, used to transmit I/O module diagnostic

information between MP channels.

Functional Features

High redundancy design: Adopting triple redundancy (TMR) structure, there are three identical sub circuits, each of which is independently

controlled. There is also a dedicated hardware/software architecture to "vote" on inputs and outputs, ensuring that the system can still

operate stably and safely in the event of partial module failures.

Real time processing capability: supports high-speed, real-time data processing and decision-making, and can adapt to high complexity and

high demand control tasks.

High Security: Compliant with SIL3 security standards, suitable for critical applications that require high security.

Multiple communication interfaces: Supports multiple communication protocols such as Modbus and Ethernet, and can seamlessly integrate

with other control systems or devices.

application area

Safety Instrumented System (SIS): Used to ensure process safety, equipment protection, and emergency shutdown.

Process control: widely used in industries such as petroleum, natural gas, chemical, and power, providing reliable automation control and

monitoring.

Emergency Shutdown System (ESD): Perform emergency shutdown operations in critical situations to prevent catastrophic events from

occurring.

Distributed Control System (DCS): Provides efficient distributed control and management to ensure the safe operation of critical equipment.
