- Dual‑Ethernet and dual‑serial port design support redundant communication link deployment
- Realizes safety‑system data publishing to HMI and third‑party host systems
- Supports read‑only access for external host, prevents unsafe write command to safety logic
- Per‑port communication link fault diagnosis and status LED indication
- Hot‑swap operable under valid Trusted system configuration
- Data filtering function, blocks invalid external data packets from disturbing safety controller operation
Application Scenarios: Safety instrumented system data uploading to DCS and HMI, petrochemical plant safety system host communication, power plant safety system monitoring data transmission, offshore platform safety system external data interaction, third‑party industrial equipment Modbus data interconnection.
Material Composition:
- Module housing: Flame‑retardant metal‑plastic composite frame
- Circuit substrate: Conformal coated multi‑layer industrial PCB, industrial communication processor chips
- External interfaces: RJ45 Ethernet sockets, screw‑type RS‑485 terminal blocks
- Backplane connector: Gold‑plated 96‑pin industrial backplane connector
- Fastening hardware: Anti‑corrosion stainless steel locking components
Structural Characteristics: Standard Trusted rack‑mount module form factor. Front‑panel contains Ethernet RJ45 jacks, RS‑485 terminals and communication status LED indicators. Rear‑side 96‑pin backplane connector completes data interaction with TMR main processor. Internal isolation barrier separates external communication circuits and safety logic circuits. Dual side spring latches achieve mechanical locking inside rack slots.
Working Principle: T9100 obtains safety system process data and diagnostic information from Trusted main controller via rack backplane. The module packs data frames according to Modbus protocol standard, transmits data out through serial or Ethernet ports. Incoming external host requests pass protocol parsing and safety filtering. Only permitted read‑type instructions are forwarded to safety controller. All communication channel faults are detected internally and reported to main processor.
Installation Requirements:
- Insert T9100 module into suitable slot of Trusted controller rack.
- Lock side latches completely to ensure reliable backplane connection.
- Deploy shielded twisted‑pair cables for RS‑485 serial communication wiring. Follow Modbus RTU termination resistor specification.
- Use industrial‑grade Ethernet cables for Ethernet connection. Complete network topology planning before commissioning.
- Connect rack protective earth to site safety grounding busbar. Strictly separate safety control network and office IT network.
Usage Notes:
- Do not connect T9100 communication ports directly to untrusted public‑level IT network. Network isolation measures must be implemented.
- Configure communication access permission parameters. Disable write access from external hosts for safety‑critical projects.
- Set proper Modbus communication baud rate, station address and network parameters, parameter mismatch triggers total communication interruption.
- Check communication cable shielding and grounding condition periodically for high‑electromagnetic‑interference sites.
- Execute hot‑swap operation strictly according to official Trusted operation procedure.
