F-PWR 02 buffer module compensates for voltage drop (up to 20ms)

（3） Power Supply and Bus

Power configuration:

Input voltage: 24VDC (-15%~+20%), ripple ≤ 5%, in compliance with SELV/PELV standards;

Redundant power supply: supports dual power input and distributes power through modules such as K 7205/K 7212;

5V power supply: H51X can accommodate up to 5 parallel F-PWRs 01, with a maximum current of 40A; H41X up to 2, maximum 10A current.

Bus design:

System bus: Dual bus (A/B), controlled by processor modules, supporting redundant communication;

I/O bus: connects I/O processing modules and I/O modules to transmit process data;

Connection requirements: The system bus should use Cat. 5e or above industrial network cables, with a minimum wire diameter of 0.2mm ² inside the cabinet and 0.5mm ² outside the cabinet.

Software and core functions

Programming tool: SILworX

Programming method: Supports IEC 61131-3 standards such as Function Block Diagram (FBD);

Variable management: supports global/local/system variables, with initial values that can be set to safe values to avoid risks during failures;

Multi tasking: Up to 32 user programs can run in parallel, supporting priority configuration.

Core functions:

Noise Blanking: The suppression time is calculated based on the safe time and watchdog time, with the maximum suppression time being equal to the safe time minus 2 times the watchdog time;

Event recording: Non volatile cache of 1000 events, distinguishing between short-term (fault) and long-term (user operation) logs;

Online diagnosis: Check module status and fault codes through LED indicator lights (3 flashing frequencies) and SILworX software;

Forcing: Supports global/local forcing, can set time limits, and requires authorization before use.

Redundancy and Communication

redundant configuration

|Redundancy level | Configuration method | Core advantages|

|Processor redundancy | 1-2 F-CPU 01 modules | Seamless takeover of redundant modules in case of single point failure|

|Redundancy of I/O modules | Grouping of 2 I/O modules of the same type | Automatic switching of channel level faults, requiring installation in different racks|

|System bus redundancy | Dual system bus (A/B) parallel | When a single bus fails, the other bus maintains communication|

|Power redundancy | Dual 24VDC power input | Single power failure does not affect system operation|

Communication ability:

Secure communication: SafeEthernet (supporting dual physical path redundancy);

Standard communication: Modbus, PROFIBUS DP (some require authorization code);

Connectivity: Up to 5 PADTs can be connected simultaneously, with 1 write permission and 4 read permissions.

Lifecycle and Maintenance

Installation requirements:

Protection level: default IP20, can be upgraded to IP54 as needed (compliant with EN 60204);

Grounding and shielding: Functional grounding enhances EMC performance, cable shielding is connected at both ends to avoid parallel connection with power lines;

Surge/lightning protection: Data lines need to be shielded, and lightning protection devices should be installed in outdoor scenarios.

Start process:

Step: Connect power → Configure rack ID/IP → Load project → Set module mode (Stop → Run) → System startup;

Troubleshooting: When the hardware and configuration do not match, the system enters the STOP/INVALID CONFIGURATION state.

Maintenance points:

Regular verification: Security related applications need to undergo regular verification testing according to the manual;

Component replacement: Fans need to be replaced regularly, and module replacement must comply with ESD protection;

Operating System Upgrade: Supports loading new versions of the operating system through SILworX.
