It supports VLAN, LLDP, port mirroring and other network functions. Speed, flow control and broadcast storm suppression can be set individually for each port.
Fieldbus Interface (2 × 9-pin D-Sub, optional)
The standard X-COM 01 has no built-in sub-modules. Protocols can be enabled by installing original sub-modules, including RS485 (Modbus Master/Slave), PROFIBUS DP Master/Slave, RS232/RS422 and SSI. The maximum baud rate of FB1 for PROFIBUS is 12 Mbit/s, and 1.5 Mbit/s for FB2. Only one protocol is allowed per single interface.
System Bus
Dual redundant system buses realize data communication with HiMax processor modules and ensure fault tolerance of communication links.
3. Status Indication System
Multiple LED indicators are arranged on the front panel. A full lamp self-test is performed automatically after power-on. Four groups of indicators with fixed flashing frequencies are adopted for status identification.
- Module Status LEDs (Run/Error/Stop/Init): Green Run LED indicates normal operation; red Error LED alerts hardware or voltage faults; yellow Stop/Init LED indicates stop status, initialization and configuration errors.
- Redundancy LEDs (Ess/Red): Indicate fieldbus redundancy operation, synchronization errors and missing redundant partners.
- System Bus LEDs (Sys Bus A/B): Show physical and logical connection status of the buses.
- Fieldbus & Ethernet LEDs: Yellow LEDs display normal bus operation; red Fault LEDs trigger alarms for bus failures. Ethernet LEDs flash along with data transmission, and can identify IP address conflict, duplex mode abnormality and data collision.
4. Software & Functional Features
Configuration Software
Compatible with SILworX V4 and V5. Network parameters including IP address, routing, ARP aging time, MAC address learning rules and ICMP mode are configurable, with a maximum of 8 routing entries supported.
Port Classification
Dedicated UDP/TCP communication ports are defined for different services, such as SNTP time synchronization, Modbus, SafeEthernet, PROFINET and SILworX programming & debugging.
Fault Handling
The module enters ERROR STOP mode immediately once a fault is detected during self-test, cutting off data exchange with external devices and local process modules, and then restarts automatically to prevent fault propagation.
Storage & Diagnostics
Non-volatile memory stores the operating system and fault logs. Historical diagnostic data can be retrieved via SILworX.
Periodic Testing
A Proof Test for integrity verification is required every 10 years in accordance with relevant standards to guarantee long-term operational reliability.
5. Accessories & Model Coding Rules
This module must be used together with the separately purchased X-CB 001 02 adapter board. When fieldbus sub-modules are installed, the model will be updated to X-COM 010 XY (X = Protocol code of FB1, Y = Protocol code of FB2). Fieldbus sub-modules can only be installed by the original manufacturer. Unauthorized disassembly and modification by users are prohibited.
