Selection Guide
Use the following criteria to determine whether the NFCP501-W05 S2 is the right module for your application:
- Step 1 — Identify your controller platform: Confirm your rack is FCN-100 or FCN-500 series
- Step 2 — Check revision requirements: S2 revision is required for firmware v3.x and above
- Step 3 — Assess memory needs: W05 = 5 MB application memory; upgrade to W10 if project size exceeds this
- Step 4 — Verify slot position: CPU module must occupy Slot 1 of the FCN base unit
- Step 5 — Confirm communication requirements: Ensure Ethernet port count and protocol support match your network design
- Step 6 — Contact Konmask: Our engineers can validate your BOM and recommend the optimal configuration
