This example uses variables. You may also use constants for the input variables.

Example
In this example, the same POU header is used for all programming languages. For an example
using IL (instruction list), please refer to the online help.
POU header
All input and output variables which are used for programming the function block TM_1ms_FB are
declared in the POU header. This also includes the function block (FB) itself. By declaring the FB
you create a copy of the original FB. This copy is saved under
Alarm_Control
, and a separate
data area is reserved.
Body
As soon the variable
Start_contact
becomes TRUE, the timer
Alarm_control
will be started. The
variable
EV
of the timer is set to the value of
SV
. As long as
Start_contact
is TRUE, the value 1 is
subtracted from
EV
every 1ms. When
EV
reaches the value 0 (after 1 second as SV = 1000 with
the timer type TM_1ms_FB), the variable
Alarm_Relay_2
becomes TRUE.
As soon as the value of the variable
EV
of the timer is smaller than or equal to 500 (after 0.5s) and
EV
is unequal 0,
Alarm_Relay_1
is set to TRUE.
