This is a quite a difficult task without any sort of help or training.

I would contact your local Siemens rep. Get him to come round with some demo equipment. If you're lucky he might even put the rig together and start the software by adding the correct hardware config etc. Especially if he thinks he's going to get your company to change from Allen Bradley to Siemens.

;-)

Thats quiet a big task for you to do if you have no experience of Siemens... I would ask your company to send you on a training cours... If you check the Siemens website for a S7 300 manual theres loads of info available on there...

Hello md.abdullah;
I would propose you study the S7-300 tutorial modules that you download from Siemens:
https://www.automation.siemens.com/...download_training_material/Pages/Default.aspx

They are designed for step-by-step learning, and cover most aspects of Step 7 configuring and programming, so they are an excellent way to prepare for the task you are given.
Hope this helps,
Daniel Chartier

A #start_stop
o #abilita
AN #ritardo
= #abilita

AN #start_stop
L S5T#100MS
SD #ritardo

Can any body tell me the meaning of this?

Hi jayasiri,

You should really start a new thread for this but, basically, your software will allow #abilita to come on when #start_stop is pressed.

It will then keep #abilita on for as long as #start_stop is held in.

If #start_stop is de-energised (released if its a push button) then #abilita will stay energised for a further 100ms (as determined by the timer #ritardo).

Thanks bkottaras and uptown47
