Structured Text - TONR

How do you make a user defined tag which has multiple attributes like the TONR timer? Can you make your own tag which has the same functionality as a TONR? Can anyone share how they used TONR in a fail to start/stop sequence.. Thank you in advance..

I'm assuming it has to do with "data type"... reguarding functionality..

This is what I need to do. I want to control a fail to start/stop output with the TONR timer. when a local or remote start signal is generated and the pump is not running I need the TONR timer to start. If the pump starts before my TONR PRE, I need the ACC or accuulated time to reset to zero. If pump does not start I need the timer DN to go high. How do I acheive this in structured text using RSlogix5000? Any tips.. anything will be greatly appreciated..

This is what I have so far..

//Once start command is issued, start time delay for timer timing
if Pump.StrtCmd AND NOT Pump.Running then
Pump.FailToStrtTMR.TimerEnable := 1;
Pump.FailToStrtTMR.PRE := 50;
end_if;
//Generate fail to start alarm if pump start fails.
if Pump.FailToStrtTMR.DN then
Pump.FailToStrtALM := 1;
Pump.FailToStrtTMR.TimerEnable := 0;
end_if;

Think about how you could do it in ladder or FBD. Conceptually, that's easier to visualize. Then, convert it to ST.

Sounds like a plan.. Thanks.. Does what I have look like something going in the right direction?

Thank you..

Anyone know of some documentation on the Rslogix5000 emulator?.. Not sure how to use it and I need to check some code out.
