HIMA HIMax X-SB 01 System Bus Module

HIMA HIMax X-SB 01 System Bus Module

Safety regulations and environmental requirements

（1） Core security requirements

Expected use and protective measures

The module is used to assemble safety related controller systems and must comply with SELV/PELV safety ultra-low voltage standards. Additional explosion-proof measures must be taken for use in Ex areas;

ESD protection: Only personnel with knowledge of electrostatic protection are allowed to operate. ESD wristbands should be worn during work, and when idle, they should be stored in anti-static packaging to avoid damage to the module caused by static electricity.

Residual risk and emergency response

Residual risk sources: engineering design defects, user program errors, wiring faults, which need to be avoided through compliant configuration and regular testing;

Emergency principle: The module is a component of the safety system, and in the event of a malfunction, the system must enter a safe state (such as emergency shutdown). It is prohibited to perform operations that obstruct the safe operation of the system in emergency situations.

（2） Environment and installation conditions

Specific parameter specifications for the required type

The protection level IP20 (IEC 60529) needs to be installed inside the control cabinet to prevent dust and condensation water

If the working temperature exceeds 0...+60 ° C, it needs to be downgraded to avoid module overheating

Storage temperature -40...+85 ° C must meet this range during transportation or idle use

Pollution level II (IEC/EN 61131-2) is applicable to non-conductive dust environments

Evaluation of heat dissipation and insulation performance is required in high-altitude areas with an altitude of less than 2000 meters

Supply voltage 24 VDC (-15%...+20%) ripple factor ≤ 5%, requires independent power supply

Product Description and Core Features

（1） Basic characteristics of module

Functional positioning and compatibility

Slot 1 and Slot 2 can only be inserted into the HIMax motherboard, supporting two operating modes:

Single module (Mono mode): Only one system bus works;

Dual module (Redundancy mode, recommended default): 2 redundant system buses to improve availability;

Safety certification: certified by T Ü V, supporting SIL 3（IEC 61508/61511/62061）、Cat. 4（EN 954-1）、PL e（EN ISO 13849-1）， Data transmission adopts security related protocols.

Fault response mechanism

If a system bus fails, the redundant bus will automatically take over communication (dual modules need to be pre configured) to ensure uninterrupted data transmission; The module has built-in self detection function, which can identify hardware/software faults and power supply abnormalities. Fault information is displayed through LED indicator lights and SILworX diagnostic interface.

（2） Hardware Structure and Interface

core component

Security related processor system: 1oo2 architecture (1 out of 2), controls and monitors a single system bus (Slot 1 corresponds to bus A, Slot 2 corresponds to bus B), the operating system and fault logs are stored in non-volatile memory and can be read through SILworX;

Interface configuration:

Number of Interface Types, Functions, and Parameters

PADT service interface 1 connects to programming and debugging tools (10/100 Base-T, does not support automatic crossover, point-to-point requires crossover, IP address can be configured)

System bus interface (Up/Down) 2 connects to other baseboards (supports automatic crossover, requires CAT 5e or above Ethernet cable, RJ-45 interface)

Diagnostic interface (Diag) 1 reserved for future expansion use

Grouping and meaning of LED indicator lights

There are a total of 6 sets of LEDs on the front end of the module, and a full light test will be conducted when powered on. The status meanings of each indicator light are as follows:

Module status indicator lights (Run/Error/Stop/Init):

Run (green): Constant light indicates normal operation (RUN state), slow flashing (600ms on/600ms off) indicates STOP/OS_SOWNLOAD state;

Error (red): Constant light/slow flashing indicates detection of internal faults (such as hardware failure, power supply abnormality);

Stop (yellow): Constant light indicates STOP/valid configuration, slow flashing indicates STOP/invalid configuration;

Init (yellow): Constant light indicates Initiate initialization, slow flashing indicates LOCKED locked state.

Redundant indicator lights (Ess/Red):

Ess (yellow): Always on indicates single bus operation (removing modules can cause system failure), slow flashing indicates redundant configuration but backup modules are unavailable;

Red (yellow): Always on indicates redundant operation (bus ID synchronization successful), off indicates no redundancy.

Other indicator lights: Rack connection light (Up/Down, green/yellow indicates physical/logical connection status), Slot light (3-18, green indicates slot has module and connection is normal), Ethernet light (PADT/Up/Down/Diag, green flashing indicates data transmission, yellow indicates speed/duplex mode).
