Not working TON function block

Hi all,

I have an strange problem in my FX2 PLC.

It`s about an program created in FBD language, in the GX works2 software. (FX2-32MR-ES)
I have an regulair TON block, created an input signal and an PT value.

But when the PT value is larger then 3276 seconds, the TON timer will not run.

See attachments....
An PT value of 3276 s (T#54m36s) and lower, then the TON timer runs, and you can see the ET value increase.
An PT value of 3277 s (T#54m37s) and higher, then the timer will not run, and the ET value remains "0".

Have searched in the PLC parameter settings if there is some limitation, but can`t find something like this.

Does anyone knows what i`am doing wrong?

Sorry, I was to early with my question...
When searching further in the manual i`ll see the answer!

But are there only 100ms, 10ms and 1 ms based timers?
Is it possible to create an low speed 1 second timers and have an bigger range 32767s?

You can always use the one second clock pulse and increment a register value.
