How to check the version of Allen Bradley PLC *.ACD Software Version without using RSLogix 5000

 Ok.. here is my situation.. 

I need to know the project database backup file version (ACD file) of my Allen Bradley PLC..

Reason is.. if you want to open it using RSLogix5000 or now called Studio 5000.. you need to know what version of your PLC file.. 

Since i only have the *.ACD file - what i did was.. try open via Notepad..

It will show up as below..

In below example... the PLC database version is v20.01.00

Calculate Natural Gas Compressibility Factor (Z) using Gas Composition Value

This time.. i have to do some analysis to see how much is the impact of natural gas composition towards Compressibility Factor (Z value)..

You see.. not every company can invest on Gas Chromatography (GC).. (expensive to own and maintain)..

So.. in our plant.. the natural gas is only corrected to actual Pressure and Temperature.. the Z-correction cannot be done due to unavailability of GC machine..

So i found this free software which is very coool.
You key-in gas compo - and it will calculate for you the Z-Value..
