EMG NET16 Series Technical Notes

The NET16 platform is widely integrated into legacy DCS and SCADA architectures across Europe, the Middle East, and Asia-Pacific. Its continued presence in operational plants — many with 20+ year design lifetimes — creates sustained demand for spare parts, replacement boards, and lifecycle extension services.

The Evolution of NET16 Architecture

The NET16 series was introduced as part of EMG's second-generation distributed I/O strategy, succeeding earlier single-board relay interface modules. The platform standardized on a 16-channel network node architecture, allowing scalable expansion through daisy-chained backplane segments. Early revisions (NET16-1.0, NET16-1.1) used parallel bus communication with proprietary EMG protocol framing. Version 1.2 — the most widely deployed revision — introduced improved noise immunity, revised firmware addressing, and compatibility with EMG's NET-BUS fieldbus standard.

Quality Control for the NET16 Range

NET16 modules present specific testing challenges due to their integrated backplane bus transceivers and proprietary NET-BUS communication protocol. DriveKNMS applies the following test protocol to all NET16 units:

Visual inspection: PCB trace integrity, capacitor condition, connector pin alignment
Power-on test: Supply rail verification (3.3 V, 5 V, 24 V) under load
Bus communication test: NET-BUS frame transmission and acknowledgment verification using EMG-compatible test master
Channel-level functional test: Each I/O channel exercised at rated signal levels
Burn-in: 48-hour continuous operation at 40°C ambient prior to shipment
Firmware version verification: Confirmed against known-good NET16 firmware image library
