19.1.5 Timer...
TP
Provided by standard.lib.
The function block Timer is a trigger. TP(IN, PT, Q, ET) means:
IN and PT are input variables of the BOOL and TIME types respectively. Q and ET are
output variables of the BOOL and TIME types respectively. If IN is FALSE, Q is FALSE and
ET is 0.
As soon as IN becomes TRUE, the time will begin to be counted in milliseconds in ET
until its value is equal to PT. It will then remain constant.
Q is TRUE as from IN has got TRUE and ET is less than or equal to PT. Otherwise it is
FALSE.
Q returns a signal for the time period given in PT.
