ð Inputs (Variable type: VAR_INPUT)
Identifiers Data type Signal type Info/possible settings
bEnable Bool binary Activating the signal generator
FALSE Signal generator deactivated, bOut = FALSE
TRUE Signal generator activated
wTimeHigh Word − High time in [ms]
wTimeLow Word − Low time in [ms]
Outputs ð (Variable type: VAR_OUTPUT)
Identifiers Data type Signal type Info
bOut Bool binary Boolean square wave signal
If the FB is activated by setting
bEnable to TRUE, the set square wave signal is output at bOut
starting with the state HIGH:
bEnable
bOut
wTimeHigh
wTimeLow
·
If
bEnable is reset to FALSE, the bOut output is also immediately reset to FALSE.
