Machine states
Map the available running, stopped, or alarm signals. Agree what each state means with the operator.
PLC data collection for existing machines
Read configured machine states, counts, and measurements with Orenda Box. Use them in MES, SCADA, and maintenance investigations.
Give each signal a clear meaning
A programmable logic controller (PLC) value needs context. Define its address, data type, unit, and machine before using it in a report. Orenda Box reads configured tags through its PLC collector. Installed applications use the permitted signals for their own tasks.
What can you collect?
Production counts
Read available part or cycle counts. Check when the counter resets and whether it counts total or accepted production.
Process measurements
Collect available temperature, current, pressure, or other values. Confirm the sensor, unit, scaling, and reading interval.
Validate a small tag list first
The collector includes Siemens S7 and selected Modbus TCP/RTU drivers, including Panasonic, Delta, and INVT IVC. Driver support does not confirm every controller model or memory area. Check the exact PLC, firmware, address map, and network during setup.
- List the PLC model, connection, and required tags.
- Configure addresses, types, units, and reading intervals.
- Compare readings with the machine’s local display.
- Test counter resets, connection loss, and restart before adding more machines.
Use the signals where they matter
Production monitoring
Map states and counts into the workcenter. Add the product, shift, and stop reason in MES.
SCADA screens
Bind approved values to an operator screen. Show trends with the relevant process context.
Maintenance evidence
Retain relevant measurements and compare suitable operating periods. Check storage and history requirements during setup.
PLC data collection questions
Can we connect an older machine?
Often the first step is to inspect its controller and available interface. A readable PLC, suitable gateway, or additional sensor may be needed. Confirm the exact connection before selecting the installation.
Does data collection change the PLC program?
Reading configured values does not require the collector to rewrite PLC logic. Making a missing signal available may require work by your automation team. Agree any program changes separately.
Is PLC data collection the same as remote programming?
No. Collection reads selected data for applications. Remote engineering access is a separate task with its own tools, permissions, and commissioning checks.
Start with one machine and one tag list
Bring the PLC model, connection details, and the values your team needs. We can scope the first reading test.
