Detector control MK is triggered on the flag’s falling edge (dashed line).
PLC-ANALYZER pro 5 makes the problem clear. There is something wrong at the end switch SR01 (see trigger), because it is active at the same time as SA01.
For clear documentation, every signal can be given free text as comment.
This type of data acquisition can be done within any desired recording time interval.
Cycle time optimization
Determination of dead time in a production facility in order to optimize run time
The acknowledgement signals READY_1 to READY_7 signal the end of certain subprocesses that have all been started together with INIT.
With PLC-ANALYZER pro 5, you can see that station 3 (READY_3) was the last station to finish.
The time measurement function determines the working time of station 3 to be 46,8 seconds.
The measurement results show the design engi-neer that station 3 must be investigated further in order to increase system speed.
PLC-ANALYZER pro creates a general overview of PLC signals and their time behaviour
You as a service technician are called because of a plant breakdown.
PLC-ANALYZER pro 5 creates for you immediately a general overview of important PLC signals and their time behaviour.
Displaying the cursor position you can read the current measured values at once. Thereby you are able to combine analogue and digital signals in the display. The analysis is made easy by time measurement and search functions for bit patterns and flanks.
Differnet numeric interpretations (bit, byte, word, double-word, decimal, binary, Hex, ASCII ...) and an arbitrary measured value scaling is possible without any problems.
So the PLC-ANALYZER pro 5 helps you solving different assignments in the field of plant maintenance.
Comparison of two signal files for a rolling mill
For the analysis the current recording from 17. April, 2009 is compared with an older recording from 17. February, 2009.
Visual comparison takes place by overlapping the signal files. Input bit E 32.2 serves as common reference point.
The time measurement function determines that the timer T1 started 5,100 s later. This strongly indicates slower running times in the system.
PLC-ANALYZER pro 5 can be used in this way to analyse differences in signal files (runtime slow-downs, wear and tear ...).
