HIMA X-COM 01 Communication Module
The HIMA X-COM 01 is a communication processor module designed for the HIMax Safety Instrumented System (SIS). Its primary function is to handle data exchange between the HIMax system and external networks, control systems, and monitoring stations, while maintaining the integrity and safety certification of the overall system.
Key Technical Specifications
Module Type
Communication Processor
Manages communication protocols and data transfer.
System
HIMax PES
High-availability, fault-tolerant platform for safety applications.
Safety Integrity Level (SIL)
SIL 3
While not directly part of the safety control loop, the module is certified to maintain the overall system integrity and diagnostics required for SIL 3 environments.
Ports/Interfaces
Ethernet (typically 2 ports)
Provides redundant or separated network connections.
Supported Protocols
FDT/DTM, Modbus TCP, OPC, HIMA proprietary protocols (e.g., safe etherCAT, HINET)
Enables integration with various industrial networks and supervisory control systems (SCADA/DCS).
Function
Data Exchange and Diagnostics
Facilitates configuration, monitoring, remote diagnostics, and data logging.
Data Synchronization
Yes
Ensures time synchronization and data consistency across redundant CPUs and communication paths.
Configuration
Via HIMax Engineering Tool
Configurable through the standard HIMA software suite.
System Connection
HIMax System Connector
Connects to the HIMax backplane.
Function and Application
The X-COM 01 module acts as the secure gateway between the high-speed safety-critical bus of the HIMax backplane and external non-safety networks. Its key roles include:
Process Visualization: Transmitting process data and system status to Human-Machine Interfaces (HMI) and Supervisory Control and Data Acquisition (SCADA) systems.
Maintenance & Diagnostics: Allowing technicians to perform remote diagnostics, monitor module health, and access event logs without interfering with the active safety functions.
System Integration: Providing the interface for communication with Distributed Control Systems (DCS) for process control coordination.
Configuration Download: Facilitating the secure download of application programs and configurations from the engineering workstation to the HIMax CPU.
Key Advantages of the X-COM 01
Isolation: Provides a clear boundary between the safety-critical domain (HIMax backplane) and the non-safety external networks, preserving the functional safety of the SIS.
Flexibility: Supports a wide range of standard industrial communication protocols, making integration into existing plant architectures straightforward.
High Data Integrity: Implements mechanisms to ensure data transmitted externally accurately reflects the safety PLC state and vice versa.
Installation Notes
The X-COM 01 is typically installed alongside the Central Processing Unit (CPU) modules in the HIMax rack, and its performance is scalable with the system's overall communication demands.
