9.10.3 Execute trace
Once the desired variables and trigger conditions have been selected, press the "EXECUTE
TRACE" softkey so the CNC starts capturing data.
When the selected trigger condition is met, the trigger line shown in the information window changes
colors.
While the trace is being executed, the information window shows the text "Trace status:
CAPTURING".
The trace will end when the internal memory buffer dedicated to it is full or if it is interrupted by
pressing the "STOP TRACE" softkey. While the trace is being executed, the information window
shows the text "Trace status: COMPLETE".
Data capture
The data capture takes place at the beginning of each cycle (PRG and PE) after reading the physical
inputs and updating the marks corresponding to the CNC logic outputs and just before starting the
program execution.
Use this instruction to carry out another data capture while executing the PLC cycle.
With this instruction, it is possible to capture the data of the signals that vary with frequencies higher
than the cycle time and data of signals whose status changes while executing the cycle, but have
the same status at the beginning and at the end of the cycle.
Example of how to use the "TRACE" instruction:
PRG
-----------
TRACE Data capture
-----------
TRACE Data capture
-----------
TRACE Data capture
-----------
END
PE 5
-----------
TRACE Data capture
-----------
END
The data capture in the execution of the trace in this program takes place:
At the beginning of each PRG cycle.
Every time the periodic cycle is executed (every 5 milliseconds).
3 times while executing the PRG module.
Once while executing the PE module.
This way, by means of the "TRACE" instruction the data capture can be done any time, especially
at those program points considered more critical.
This instruction must only be used when debugging the PLC program and it should be avoided once
the PLC program is fully debugged.
