    Top Questions from OKmarts Buyers

    • Q: Are software licenses, firmware updates, and configuration files included with hardware like HMIs and PLCs?

      A: Hardware units ship with standard factory-default firmware. For proprietary programming software or specific firmware flashes required for legacy system compatibility, buyers must consult our technical support team during procurement to confirm licensing terms.

    • Q: Can OKmarts provide specialized industrial packaging for sea freight or long-term tropical storage?

      A: Yes. For international shipping or extended warehouse storage in high-humidity regions, we offer upgraded industrial packaging options. This includes vacuum-sealed anti-static (ESD) barriers, desiccant packs, heavy-duty wooden crates, and shock-absorbent padding tailored to withstand harsh maritime transit conditions.

    • Q: Can OKmarts assist in verifying technical compatibility before I place a high-value order?

      A: Yes. Buyers can upload existing equipment nameplates, system schematics, or parameter requirements. Our applications engineers will cross-verify physical dimensions, electrical ratings, and communication protocols (e.g., Profinet, EtherCAT) before finalizing the order.
