It is not possible to use this function in a function block POU.
For correct results, timer functions and timer function blocks
must be executed exactly one time in each scan. Thus it is not
allowed to use timer function or timer function blocks in
interrupt programs or in loops.
Every used timer must have a separate constant Num*.
Available Num* addresses depend on system registers 5 and
6.
Timer of type TM_1s, TM_100ms, TM_10ms, TM_1ms use the
same Num* address range.
The system timer functions (TM_1s, TM_100ms, TM_10ms,
and TM_1s) use the same NUM* address area as the system
timer function blocks (TM_1s_FB, TM_100ms_FB,
TM_10ms_FB, and TM_1s_FB). For the timer function blocks
the compiler automatically assigns a NUM* address to every
timer instance. The addresses are assigned counting
downwards, starting at the highest possible address. In order
to avoid errors (address conflicts), these timer functions and
function blocks should not be used together in a project.
This function does not require a variable at the output "T".
