Industrial IT - PLC and machine integration with Nexa Edge

Workstream 03 — Industrial IT Specialist Goal: Study and validate a safe, repeatable way to collect useful machine data for Nexa and document customer‑side prerequisites for commissioning.

Your project

• Survey the machine, PLC, SCADA, historian, and available customer‑approved interfaces; recommend a connection route based on site constraints.
• Configure and test read‑only collection through Nexa Edge using OPC UA and, where supported and authorized, Siemens S7 or Modbus TCP.
• Prepare a tag inventory covering signal name, source, meaning, unit, operating range, update behavior, and known limitations.
• Validate timestamps, units, signal changes, buffering, reconnect behavior, and data availability using a test bench or authorized machine connection.
• Document responsibilities and steps for Nexa and customer IT/OT teams, including network access, accounts, firewall rules, and acceptance checks.

Expected deliverables

• Connection proof of concept to an agreed test setup or authorized machine using Nexa Edge (read‑only).
• Tag inventory and mapping proposal for the Data Engineer (source, meaning, units, behavior, quality notes).
• Commissioning and network guide with prerequisites, sequence, and a network/data‑flow diagram for customer IT/OT and Nexa teams.
• Test report covering normal operation, disconnection/reconnection, buffering (where supported), and known limitations.

Profile and skills

• Final‑year student in industrial IT, automation, electrical engineering, mechatronics, or computer engineering.
• Familiar with PLCs, industrial networks, SCADA, and troubleshooting; able to document and coordinate technical work across teams.

Useful experience

• Siemens PLCs, OPC UA, Modbus TCP, Industrial Ethernet, Python, factory commissioning.
