Cross Cutter
Features of the "Cross Cutter" prepared solution
 Prepared Solution Servo PLC / ECSxA 1.1 EN 2-69
Variable names
Inputs
Global variables (Variable type: VAR_GLOBAL)
Name Data type Value/Meaning
Variable to reset the counter for mark signals located outside the mark window.
TRUE Reset counter.
g_bResetCounterTPOutOfWindow BOOL
FALSE Do not reset counter.
g_DFIN_bTPReceived_b BOOL Trigger input for calculating position deviation.
This signal is use for incoming print-mark-sensor signals.
This global variable is linked directly to SB DFIN_IO_DigitalFrequency. Digital
input I5 is assigned to the mark sensor!
g_DFIN_dnIncLastScan_p DINT
Δ incr between mark sensor signal and start of task. This global variable is linked
directly to SB DFIN_IO_DigitalFrequency.
g_dnTPPositionWindow DINT Size of mark window in 0.0001[m_units].
This value is displayed in code C3669/000; this variable can be written to this code.
The value is converted into increments internally. If you use this variable, to avoid
inconsistencies, do not write variable g_dnTPPositionWindow_p!
g_dnTPPositionWindow_p DINT Size of mark window in [incr.].
If you use this variable, to avoid inconsistencies, do not write variable
g_dnTPPositionWindow!
g_wMaxNumberOfTpOutOfWindow WORD Number of cycles permitted with no mark signals appearing in the mark window. If
this number is exceeded, a warning signal will be generated. This value is displayed
in code C3670/000; this variable can be written to this code.
Outputs (Variable type: VAR_GLOBAL)
Name Data type Value/Meaning
g_bXTpReceived BOOL Output signal for mark correction. This output signal outputs all print-mark signals
located inside the defined mark window. All other print-mark signals are not output.
This output indicates the time at which the window is open.
TRUE The mark window is open. Incoming mark signals are output at
g_bXTpReceived.
g_bTpWindowOpen BOOL
FALSE The mark window is closed. Incoming mark signals are not
output at g_bXTpReceived.
This output indicates that the mark window is active and the first print-mark signal
has been received.
TRUE The mark window is active.
g_bTPWindowActive BOOL
FALSE The mark window is not active. The first print mark has not yet
been detected.
g_dnTPDistance_p DINT This output signal indicates the distance between two print marks in increments.
