How weighbridge software integrates with FCI Hafed

A technical walk-through written for IT teams + procurement officers

Of all the "the weighbridge talks to a government portal" questions, FCI Hafed integration is the one with the highest stakes. A misconfigured sync at a wheat procurement yard during peak season means tens of trucks waiting, manual fallback slip-writing, and reconciliation work that can run for weeks. We have integrated EagleOS with the FCI Hafed workflow at multiple state procurement yards. This is what the integration actually involves, written for the IT manager who has to approve it and the procurement officer who has to operate it.

What FCI Hafed integration actually means

In plain language: when a truck weighing wheat or paddy completes a weighment at your yard, the data must arrive at the FCI Hafed central system without manual data entry. If it doesn't, the farmer cannot get paid, the truck cannot be dispatched, and the procurement officer has to re-key everything later. Integration eliminates that lag — and the data-entry errors that come with it.

The end-to-end workflow, step by step

At a procurement yard with EagleOS + FCI Hafed integration enabled, here is what happens between a truck arriving and the farmer's bank account being credited.

1. Pre-procurement: party master sync. Before the season starts, EagleOS pulls the FCI Hafed party master — the list of registered farmers, traders, and cooperative societies eligible to procure through that yard. This happens once and is refreshed daily. The operator selects from this list at weighment time; no free-text entry.
2. Truck arrives → weighment. The operator enters truck registration, selects the party from the master, selects the grain grade (wheat-FAQ, paddy-A, etc.) from the FCI-validated dropdown, captures gross weight on the indicator.
3. Tare lookup. If the truck has a registered tare in the FCI system, EagleOS pulls it. Otherwise the truck is sent for a tare weighment.
4. Slip generation. Net weight is calculated. EagleOS auto-generates the FCI-format slip with a unique slip number, prints it on the dot-matrix printer, and saves a local PDF copy.
5. Real-time push to FCI Hafed. The slip data is pushed to the portal API immediately. The portal acknowledges with a server-side reference number, which EagleOS prints on the slip.
6. Dispatch routing. The portal returns the destination godown for the truck. EagleOS prints the routing on the slip + sends an SMS to the farmer's registered phone.
7. End-of-day reconciliation. A summary push at end of shift confirms every slip was received and acknowledged. Any failed push is queued and retried until the portal accepts it.

What you need before integration starts

The integration cannot begin until five things are in place. Get all five lined up before the EagleOS team arrives, and live-sync is achievable in a single day.

1. FCI Hafed portal credentials. Your yard's registered user account on the procurement portal, with API-access permissions. This is requested through the FCI district office; takes 2–3 weeks.
2. Internet at the yard. Wired broadband ideally; 4G with a backup plan acceptable. Bandwidth needed is small (under 1 Mbps), but reliability matters because queued slips eat memory.
3. Windows PC + indicator + printer. EagleOS runs on Windows 7/8/10/11. The indicator (an Eagle CFR-02 or compatible third-party 24-bit board) connects via RS-232 or USB-Serial. The printer is dot-matrix (standard FCI requirement) — Epson LX-310 is the typical choice.
4. Operator + supervisor trained on the FCI workflow. Not on EagleOS — on the FCI side: how to handle a rejection, how to handle a late dispatch routing response, how to handle a tare-not-found case. EagleOS shows the right buttons, but the operator has to know the procurement logic.
5. A test party + test grade in the FCI sandbox. The integration is verified end-to-end in sandbox mode before going live. The FCI district IT desk provisions this.

The data fields that flow over the wire

For a single weighment, EagleOS pushes ~25 fields to the FCI Hafed portal. The schema is broadly stable across seasons but minor field changes happen most years.

The portal validates every field. Common rejections: grade_code not in the season's allowed list, net_weight_kg outside the FCI per-truck min/max for that grain, party_id not in the daily-refreshed master.

How sandbox testing works

Every FCI Hafed integration starts in sandbox. The sandbox is a parallel environment with a copy of the production schema but with dummy data, dummy parties, and no real procurement effect. The point is to verify your software can complete the round-trip — submit, get the portal reference, print the slip, handle a rejection — before you let real wheat trucks through.

EagleOS supports a sandbox toggle in Settings → Integrations → FCI Hafed. With sandbox enabled, the portal acknowledges in the same shape as production but every transaction is logged with a SANDBOX flag and the portal's response includes a "TEST MODE" header. The slip prints with a clear "SANDBOX" watermark.

A complete sandbox test cycle takes 2–4 hours and validates these scenarios:

• Happy path: truck in → weighment → portal accepts → slip prints with reference
• Reject path: truck with grade not in season → portal returns error → operator sees the rejection message → corrects the grade → resubmits
• Connectivity loss: network drops mid-submit → slip queues locally → reconnects → queued slip pushes → acknowledgement received
• Tare-not-found: first-time truck → no registered tare → empty-truck second weighment → tare recorded → net calculated → portal accepts
• End-of-day: shift summary push → portal acknowledges total slips for the shift → any discrepancy flagged for the supervisor

Four pitfalls we have seen at live yards

1. Party master goes stale. If the daily-refresh fails (usually because the yard's internet dropped overnight), the operator works with yesterday's party list. A farmer who registered today is rejected at the gate. Fix: EagleOS shows a "Party master last refreshed: 14 hours ago" indicator on the operator screen — when it goes red (>24h), the operator knows to chase IT before procurement starts.
2. Time-zone clock drift. FCI's portal expects timestamps in IST. If the Windows PC clock drifts (common on yards with intermittent power), the portal rejects slips. Fix: NTP sync to time.nplindia.org on the yard PC; EagleOS shows a clock-sync indicator.
3. Indicator output format mismatch. Third-party indicators that don't follow the standard weighbridge protocol need a custom parser. We have shipped 8 custom protocol adapters over the last two seasons. Fix: confirm the indicator's RS-232 output format with EagleOS support BEFORE the procurement season starts.
4. Dispatch routing arrives slow. Some seasons the FCI portal takes 5–10 seconds to return the destination godown after a slip submit. If you print before routing arrives, the slip is missing the routing field. Fix: EagleOS waits up to 15 seconds for the routing response before printing, with a manual override for the operator if it doesn't arrive.

Realistic timeline from PO to live sync

Total: 4–6 weeks from purchase order to first live truck. The bottleneck is consistently the credential request; everything else takes hours or days. We have done first-truck-through in as little as 18 days when the procurement officer pre-requested credentials.

What maintenance looks like, year on year

FCI updates its portal API between seasons — sometimes minor field tweaks, sometimes structural changes (a new grade code, a new dispatch-routing field, a new audit signature requirement). Eagle's annual support contract covers all these protocol updates. We typically push two updates per year: one before the wheat season (April), one before the paddy season (October).

Outside of API changes, the integration is maintenance-free for the customer. Logs go into C:\EagleOS\logs\; the operator sees a sync-status pill in the corner of every weighment screen; any failed push triggers a WhatsApp alert to the supervisor.

If you have an active or planned FCI Hafed procurement yard and you are evaluating software, the EagleOS team handles FCI integrations as a standard scope. The FCI Hafed page covers the deployment specifics; the Security page covers data residency and audit posture for your IT review.
