Functional Safety & Triple Modular Redundancy Interconnect Attributes
The communication card maintains high-integrity serial data pathways to support fail-safe state execution across supervisory safety management platforms. Galvanic isolation across serial channels prevents ground loops and high-voltage industrial transients from compromising backplane bus communication velocity. The dual-port RS485 physical interface provides deterministic signal routing into redundant safety controller networks while preserving SIL3 certification parameters during active multi-node polling.
Frequently Asked Questions
Q: Does the card support hot-swapping inside a standard industrial IPC PCI slot?
A: Standard PCI bus architectures do not support hot-swapping; power down the industrial host computer before physically inserting or removing the interface card to prevent bus damage.
Q: How is terminal line impedance managed across the two RS485 ports?
A: External termination resistors (typically 120 ohms) must be configured at both physical ends of the RS485 network segment to prevent signal reflections at baud rates up to 115.2 kbps.
Field Installation Guidelines
Follow these technical procedures during card installation and field serial wiring:
- Power down the host computer system and discharge static electricity prior to handling the PCI card PCB.
- Insert the card firmly into a free standard PCI slot until the retention bracket sits flush against the industrial PC chassis.
- Secure the bracket screw to establish a solid physical ground connection between the card cover and the chassis frame.
- Connect shielded twisted-pair cables to the RS485 serial ports, ensuring correct polarity for differential signal lines (A and B).
- Ground cable shielding at a single point near the enclosure entry point to minimize high-frequency electromagnetic interference.
