SISNet Fiber Communication and Safety Network Integration
The VS6002 uses redundant optical communication paths to regenerate SISNet data frames between DeltaV SIS nodes. Therefore, the module maintains communication continuity across extended network distances while preserving SISNet deterministic update behavior.
The repeater architecture uses two repeater modules installed on a dedicated two-wide carrier. In addition, the module supports SISNet ring topology configurations with up to 32 nodes per ring.
For Emerson DeltaV SIS applications, the communication layer operates independently from standard DeltaV Ethernet networks. The VS6002 specifically processes SISNet safety communication traffic and does not function as a general-purpose Ethernet switch.
Frequently Asked Questions
Q: What communication medium does the Emerson VS6002 support?
A: The VS6002 supports multimode fiber optic SISNet communication using 62.5/125 um or 50/125 um fiber cables with ST optical connectors.
Q: Does the VS6002 provide network redundancy?
A: Yes. The module supports redundant SISNet communication through dual repeater architecture and redundant ring topology.
Q: Can the VS6002 be installed as a standard DeltaV network device?
A: No. The VS6002 is designed specifically for DeltaV SISNet safety communication and does not replace standard DeltaV Ethernet network components.
Field Installation Guidelines
- Install the VS6002 on the specified DeltaV SIS carrier assembly inside an approved control cabinet.
- Verify the 24 VDC supply polarity and power distribution before energizing the module.
- Route fiber optic cables according to SISNet ring topology requirements.
- Inspect ST optical connectors for contamination before connection.
- Maintain proper separation between fiber cables and high-voltage power wiring.
- Verify repeater status indicators and SISNet communication diagnostics after installation.
- Confirm redundant communication paths operate correctly before placing the SIS network into service.
