Selection Guide
Use the following criteria to determine whether the IC693NIU004 is the right module for your application:
- Need Ethernet on an existing Series 90-30 rack? → IC693NIU004 is the direct fit
- Upgrading CPU and want embedded Ethernet? → Consider IC693CPU374 or IC693CPU375
- Require Modbus TCP only? → IC693NIU004 supports Modbus TCP; confirm firmware version ≥ 2.10
- Need EGD peer-to-peer? → IC693NIU004 is the recommended solution
- Budget-constrained retrofit? → Contact Konmask.com for refurbished/tested units
- Multi-protocol requirement? → Evaluate IC693CMM321 or third-party gateway

Replacement & Compatibility FAQ
Q: Is the IC693NIU004 compatible with Series 90-70 PLCs?
A: No. The IC693NIU004 is designed exclusively for the Series 90-30 backplane. For Series 90-70, refer to the IC697CMM742 or IC697CMM711.
Q: Can the IC693NIU004 replace the IC693CMM321?
A: They serve different roles. The NIU004 is Ethernet-only; the CMM321 supports multiple serial protocols. They are not direct drop-in replacements.
Q: What firmware version does the IC693NIU004 require?
A: Minimum CPU firmware v9.0 or later is recommended for full EGD and Modbus TCP support. Verify with GE Proficy Machine Edition.
Q: Does Konmask.com offer tested/refurbished IC693NIU004 units?
A: Yes. Contact support@konmask.com for availability and pricing on refurbished units with warranty.
Q: Can I use a third-party Ethernet gateway instead?
A: Yes, in some cases. However, native GE modules offer better integration, deterministic performance, and full software support. We recommend the original where possible.
