The Unitronics Model V100-17-ET2 Ethernet Communication Interface Module, engineered and manufactured by Unitronics Ltd. in Airport City, Israel, is a specialized add-on communication card designed to equip Unitronics Vision Series (Vision130™, Vision350™, Vision430™) and Samba™ Series All-in-One OPLCs with high-speed industrial TCP/IP networking.

Streamlined Embedded Enclosure Architecture:
Standard Vision and Samba controllers are supplied with basic serial or USB communication interfaces. To integrate the controllers into plant-wide Ethernet backbones, the V100-17-ET2 card snaps directly into a dedicated motherboard expansion header inside the controller's rear housing:
- Zero Cabinet Footprint Penalty: Mounts completely within the physical envelope of the OPLC chassis, exposing a standard RJ45 port through the rear casing without increasing enclosure depth or demanding DIN-rail allocation.
- Auto-Negotiating 10/100 Mbps Performance: Automatically detects network transmission speeds across standard industrial Star topology architectures driven by external industrial switches or hubs.
- Dual Diagnostic Status LEDs: Features an integrated green Link LED (LNK) indicating an established physical carrier connection and an amber Activity LED (ACT) flashing in proportion to real-time data transmission/reception packets (TX/RX).

Multi-Protocol Industrial Telemetry & Remote Management:
- Industrial Modbus TCP Protocol (Master / Slave): Seamlessly links PLC registers, memory coils, and structured data tables with enterprise SCADA nodes, secondary HMIs, variable frequency drives, and smart energy meters over standard Ethernet infrastructure.
- Virtual Network Computing (VNC) Remote Desktop Access: Authorizes control engineers and maintenance supervisors to view and manipulate the controller's active HMI display in real time using free VNC viewer utilities on PCs, laptops, Android, or iOS devices.
- Embedded HTML Web Server: Hosts custom web pages generated within the PLC application, enabling browser-based process parameter inspection and machine telemetry without proprietary client software.
- Automated Email Dispatch (SMTP): Continuously monitors critical alarms and triggers automated notification emails complete with fault descriptions, real-time timestamps, and process variable values.
- EtherNet/IP & Multi-Socket Networking: Integrates easily into multi-vendor industrial networks, supporting up to 8 concurrent TCP/IP sockets for simultaneous programming, SCADA polling, and peer controller communications.
- Rapid Ethernet Program Transfers: Cuts application download, OS upgrades, and graphic element upload times from minutes down to seconds compared to legacy serial connections.

Target Industrial Sectors & Applications:
- Water & Municipal Wastewater Infrastructure: Networking distributed lift stations, water treatment aeration skids, and reverse osmosis skids to central municipal SCADA servers over fiber/Ethernet links.
- Food, Beverage & Pharmaceutical Processing: Batch recipe tracking, clean-in-place (CIP) logging, and automated packaging lines requiring central data archiving for FDA 21 CFR Part 11 compliance.
- Commercial Building Automation & Energy (BMS / HVAC): Central chiller sequencing, cooling tower variable fan control, and electrical sub-metering telemetry integration over Modbus TCP.
- Original Equipment Manufacturers (OEM Machinery): Enables remote diagnostics, machine commissioning, and software updates over secure VPNs without requiring on-site service trips.
- Cold Chain Logistics & Environmental Warehouses: Real-time temperature/humidity logging with automated email alerting to protect temperature-critical stock.
