- The value 27648 has simply been selected as the maximum normal range value of any analog signal transfered to the CPU by a Siemens analog module.This numerical value is independant of the resolution of the particular analog module used (this is a way to standardize all scaling of analog readingsin the processor)
For unipolar data, this would mean 0 to 27648 represents full range; above 27648, overrange, below 0, underrange.See the attached illustration for the equivalent numeric values iof a 4-20 mA or 0-20 mA signal.
The basic configuration of the analog modules is best explained in the S7-300 module Data manual:

Look at the chapters on Principles of Analog value processing and Representation of the analog values of analog modules.

This is a great explanation as well depiction for someone new or refreshing and well explained. I do believe the raw value limit changes depending on the type of PLC System. I mostly only work with RA-Rockwell Automations products here in the U.S. working with my Senoir Automations Engineer. My background into my current job was from a Mechanic/Plant Operator job into Field Service Engineer/Automations. I would Major Plant PLC Upgrades helping my Senoir Engineer and so much questions I’d ask because at best I just didn’t understand how a PLC operated under the hood. Scaling would confuse the hell out of me. Because sometime we be upgrading a PLC-5 system, other times a SLC system or upgrading them all to ControlLogix system and in the setting of the Analog Scaling, they are all different in their value for each the different PLCs. This confused the hell out of me for quite a while. And I do believe it can confuse others as well in not being aware of the different PLC systems or generation type of PLCs. And I think it is something to point out.
100 % agree .
No doubt this is the best explanation ever
Very well described the concept of analog system scaling with practicality in very easy terms masha'allah
❤ Mashallah may Allah increase your knowledge
Ameen
Very good tutorial man You are making Pakistan Proud !!!!
Thank you very much for easy and excellent explanation
Wonderful !! Clear Sound and great explaining mashallah .. Thanks for everything
Well done sir, Even a fresher can able to understand " what actually analog process" in industry sectors..!
It will be very benefit, if we get PID Process Concepts in any PLC with Real Time Example...! Such as value assigning for (PID Controller)
Hi thank you for the video.. can you explain how a short circuit or a circuit overload affects the raw values that go into the plc so I can better understand the value range in plc
How if you use 0-20mA analog input module for 4-20mA sensors..?
Well explained concept prof....,thanks!
mbonu chukwudi thanks dear
Why we use int data type for analog input. Please clear
Thanks sir for your good lectures. Please give more exercises to practice programming or if you can guide us for tutorials to read.
Mohamad Sadek Bahrini my pleasure
U did good work sir
Thankyou somuch
Why you square the 15?
Thanks a lot for making it easier to understand
u r welcome who training series is uploaded
u can have a look at other lectures
Clear voice plays a key role for the videos
More plc automation lectures there here.voice clearance not good.
Is this related to signal mapping? If not can u please tell me more about signal mapping?
Hello sir, waiting for scaling videos in detail in siemens. Love from 🇮🇳
That's posted already check 18 lecture
If we have multiple volume in tank as non linear values, how can we do scaling in that case
I have a 20,000-liter fuel tank how do I scale the analog input?
Thank you so much Sir
I'm going to use these videos to take over the world
Great Video
How to do percentage analogue scaling please upload video
Nicely explained. Thank you.
the beginner will not understand until they see in the ladder.
thankx
Thank you for these amazing videos
Very nice explain
thank you. vey helpfull sir.
where is lecture 18
Very good
Sir can u explain scaling on delta plc?
Good explanation.
Toturials thanks bro
wa alaikum salaam!!!! Masha Allah easy to concept understand!!!!!
Truly appreciated
excuse me. which block funtion we use in Step 7 Program to convert 4-20mA or 0-10V to 0-27648. ???
plz check second part of this video
AI module convert 4-20mA analog signal to 0-27648 for us, Right ?. and we using Scale block to convert it again to real value ?
Dear Brother please upload details about counter and comparators
thanks dear
Thanks Sir
Nouman Ali my pleasure
fantastic
ممكن شرح بالعربية
Sir provide me an video over pid controller for full control over hearter
Sahil Shukla stay connected we will surely bring more videos on it in future
Good explanation.
Thanks prof
Waseem Omran my pleasure
