4-20 mA HART Loop Protocol
The FS-DCOM-232/485 integrates with Honeywell distributed control systems, supporting deterministic communication. While designed for RS232 and RS485/422, the module maintains compatibility with instrumentation networks utilizing 4-20 mA HART loop protocol, ensuring channel isolation and stable data exchange across redundant paths.
Frequently Asked Questions (FAQ)
Q: Can the FS-DCOM-232/485 be hot-swapped during operation? A: No, the module requires system shutdown before insertion or removal to avoid bus disruption.
Q: What baudrate ranges are supported for RS485 communication? A: The module supports baudrates from 0 up to 2 MBaud, including transparent, FM0, FM1, and Manchester coding.
Q: How is input power supplied to the module? A: Input voltage is 5 Vdc ±5%, with a maximum current of 500 mA provided by the control processor(s).
Field Installation Guidelines
- Mount the FS-DCOM-232/485 securely on TS32 or TS35 rails with full mechanical engagement.
- Maintain separation between communication cabling and high-voltage wiring to reduce electromagnetic interference.
- Apply shielded cabling with proper grounding to maintain compliance with CE/TUV/UL/FM standards.
- Verify connector seating and locking before energizing the system.
- Confirm baudrate settings during commissioning to ensure proper communication.
