FAQs
Q1: What is the primary function of the FC-USI-0001?
It is a Universal Safety Interface (USI) module that acts as a secure communication gateway between the Safety Manager/FSC controller and external devices (DCS, PLC, HMI). It handles non-safety communication tasks such as reporting alarms, diagnostics, and process variables to supervisory systems, while maintaining galvanic isolation to protect the safety-critical controller.
Q2: Is the FC-USI-0001 still in production?
No. The FC-USI-0001 has been withdrawn by Honeywell. It was succeeded by the FE-USI-0002, and later by the FX-USI-0002, which is the current recommended replacement . The FX-USI-0002 is pin-compatible and functionally compatible, but requires Safety Manager software R140.1 or higher.
Q3: What communication protocols does the FC-USI-0001 support?
The module supports Modbus RTU (both Master and Slave) on its serial channels, and CANopen protocol. It features 2 x 10/100 Mbps Ethernet ports and 2 x configurable serial channels (RS232/RS422/RS485) .
Q4: What is the FC-USI-0001 used for in a Safety Manager system?
It is used for non-safety communication tasks, including connecting the Safety Manager to HMIs or DCS for monitoring, reporting alarm and diagnostic data, and transmitting process variables. It does not participate in the safety instrumented function (SIF) execution itself.
Q5: Can the FC-USI-0001 be hot-swapped?
Yes, provided the Safety Manager rack configuration supports redundant modules and firmware synchronization is fully complete before removal . The module is designed for high-reliability SIL-rated environments and supports online replacement in properly configured redundant systems.
