INT to S5T in LADDER

Really struggling to convert a variable INT to a TYPE accepted by an S7 timer.

Int is 0-255
Variable on -(SE)-
S5T#5s

Is there a simple way to convert the incoming INT to a TYPE acceptable to the above timer?
The -(SE)- wont accept MD MW or INT in LADDER.
DO I have to use a different extended pulse timer
What is the TYPE to use
This should be a really simple thing to do but am struggling in S7

Forget old S5 timers and go to IEC timers (SFB3, SFB4 and SFB5), time is esier to adjust with them and timers are not limited by plc type.
(You only need to know, that siemens IEC timers don't like of timesetting 0ms, timer never times/ output never goes to "1" state with timesetting 0ms)

But if you wan't to use s5timers, then you need to keep in mind, that s5time is two parts, timebase and number

bits 12-15 are timebase and number 0-999 is time setting.

You can use also FC40 to convert to s5time, but input is dint

100% agree with this statement.

Thanks for the feedback, I need to use the S7Timers for consistency my problem was finding the correct data types to use as they were global variables.
Gonna try with using local in the block so I can use TIME, and an FC40 but twitchy now about the updating the FB and DB live

Well that was a fail!
Tried, but had a problem with updating the FB and DB (probably the way in which I was uploading) but the main issue is creating the word in ladder to use on the timer.
I found a post on here where it had been done but was in German and I was unable to see the Variable types used or the Blocks used.
Any further posts I can look at that are coded in Ladder I am struggling to translate the mnemonic posts

Cheers

Since you are programming an FB with associated DB (instance DB), I am guessing you are programming a reusable block.
Basically, S5Timers are not suited to reusable programming. Forget going that way !

No, you must either drop programming reusable code, or drop using the S5Timers.
NB. "I need xxxx for consistency". That is a handy phrase. I have to write that down. Useful in any situation. Scott Adams would be proud.

Not sure what you are doing with the TIM_S5TI block, but I think you are headed down a dead end.

Just adding an extra timer to an existing block, the Blocks are used for different locations

All the other timers used have been S5Timers, its just a variable pulse I need so not wanting to add a single IEC timer when all the others used in the Prog were S5

I think I have managed it with a couple of standard FBs (INT operations) and the FC40. Providing the INT comes through ok on OPC!!
Will prob need to bracket the incoming value for peace of mind though.

Thanks to everyone who took the trouble to respond, I learnt a far more than I expected.
