TL;DR

The real-world headache: Mitsubishi, Siemens, Modbus and Fanuc CNC protocols mixed on one line. The TSingley DAQ engine turns 'protocol hell' into plug-and-play with 5-protocol simulation, register planning, live debugging and a clean data flow into MES-LINE.

The Real Pain: Protocol Hell

A single factory line often runs Mitsubishi PLCs, Siemens S7, Modbus devices, Mitsubishi CNCs and Fanuc CNCs side by side — each speaking a different language:

Worse, many CNC protocol documents are not public (Mitsubishi requires an application; Fanuc requires buying the SDK) — on-site debugging often means trial-and-error against docs and packet captures.

The TSingley DAQ Engine: One Engine, Many Protocol Drivers

MES-LINE's DAQ engine ships multi-protocol drivers and turns protocol hell into plug-and-play with four steps: simulation → planning → live → data flow:

5-protocol simulation → register planning → sim/live dual mode → DAQ polling → MES-LINE data flow
  (no hardware needed)  (offline verification)  (develop on sim, integrate live)  (4 data classes stored)

Step 1: Protocol Simulation (Develop Without Hardware)

The DAQ engine ships a 5-protocol simulation platform (Mitsubishi MC / Siemens S7 / Modbus TCP / Modbus RTU / generic serial), solving 'the equipment hasn't arrived, how do we write code?':

Developers tune the UI and logic in simulation, then switch to live in one click for integration — development never blocks on hardware.

Step 2: Register Planning (Verify Offline, Avoid Pitfalls)

The debug tool supports register scheme planning:

Key value: the register map is planned, verified and exported offline — no on-site trial-and-error against real devices.

Step 3: Live Debugging (Real Device Communication)

At integration time, switch to live mode with two link types:

Read, write, RUN/STOP and force ON/OFF are all supported; scheme ↔ monitor linkage (selecting a scheme auto-fills the address bar).

On-site tip: CNC protocols (Mitsubishi CNC MC / Fanuc FOCAS) differ from PLC protocols — Mitsubishi CNC reads machining state/alarms/program number/tool life/coordinates/override; Fanuc FOCAS additionally reads tool offsets and spindle load. Confirm the exact CNC model (Mitsubishi M70/M80/E80, Fanuc 0i-F/30i-B) and whether Ethernet is enabled.

Step 4: Data into MES-LINE (The Flow to Line Control)

Once verified, the register scheme attaches to a device instance; the DAQ engine manages instances by equipment UUID, polls the PLC and stores data in four classes:

DAQ Engine polls PLC
   ├─ Status    → equipment_status (snapshot) + machine_events (log)
   ├─ Process PV→ process_values (time series) — sensor readings (temp/pressure/level)
   ├─ Alarms    → alarm_records + alarm_engine (limit/fault events)
   └─ Process SV← recipe hub push (setpoints/specs, recipe activation writes sv_records)

The four data classes (local SQLite in MES-LINE) → scheduled report to ONLINE plant-wide management → OEE/CPK analytics. That is the complete path from 'PLC register' to 'HMI real-time monitoring + plant-wide reports'.

A Real Example: Mixed Mitsubishi + Fanuc CNC Line

A customer line mixes Mitsubishi CNCs and Fanuc CNCs:

Conclusion: the purpose of protocol conversion is not 'conversion' — it is making upper-layer applications blind to protocol differences. MES-LINE unifies devices of different protocols into one data model, and OEE, work-order and quality analytics all run on that model.

The Protocol Hell Can Be Walked Through

Multi-brand machines, multiple protocols, undocumented APIs — this is the reality for every manufacturer. The DAQ engine's four-step methodology (simulate → plan → connect → data flow) walks the path: development without hardware, registers verified offline, live connection tunes on the spot.
