Getting the Controller Firmware Revision Programmatically Studio 5000

[Paul_Pereira]

Hi guys. I'm trying to display the controller firmware revision number OR the logix designer version number on my panelview plus 6 HMI. So I think I need to get this value into a tag in studio 5000 so that I can display it. I've tried GSV but it doesn't seem to have the option for firmware revision of the controller. Is there a way to do this? I'm using a AB L33ER with logix designer 33.

Use Class ControllerDevice and Attribute ProductRev. Return value is an INT value in HEX with the low byte the major rev and the high byte the minor rev.


I ran it on my test bench and the decimal return is 2850. Going to the tag monitor window and switching to HEX shows 16#0b22. Low byte 0x22 is 34 decimal and high byte 0x0b is 11 decimal, which corresponds to my v34.11 processor.


To find this in the help file, highlight the GSV instruction and press "F1". Scroll to the end and click the link "GSV/SSV Objects". Click the link "ControllerDevice" for a list of attributes. There are others there that you might find useful, like Status and ProductCode (returns an integer corresponding to the model name).

Hexadecimal Help

Hi Joseph,

Thanks for replying. With your instruction I managed to get a decimal of 3105 and the hex style gave me a value of 16#0c21. I'm not entirely sure how to convert this value into plaint text though? What is 16#0c21? I tried hexadecimal converters but they just claim that 16#0c21 is not a hex value.

0C in HEX is 12 in DEC
21 in HEX is 33 in DEC
which corresponds to V 33.12

Almost there

Thanks Tarik,

Ok so now I understand that this means I should take the last four characters to get my version number. starting with 21 to get 33 and 0C to get 12. Is there a way to programmatically convert this directly. At the moment I am copying the value out and pasting it in an online converter. Is there a way the PLC can do this itself?

You can use Move with Mask instruction (MVM)

Mvm

Thanks for the help Tarik. So I should use my value of 16#0C21 as the source? And what do I put in as the mask?

Here is an example. The BTD instructions isolate the major and minor versions into their own tags. Then if you want to combine them, the CPT is used to add them and store the result in a REAL tag. Note that the GSV_ControllerRev tag is configured to display as HEX. That's why we see HEX in the GSV destination.

OG

2 MVM instructions, one with Mask 16#00FF and the other with 16#FF00

It's done!

Thank you all! I tried the bit with the BTD and it worked perfectly!

I used a COP instruction to get the INT tag returned by the GSV instruction into a SINT[2] array. Element [0] of the destination array got "34" decimal and element [1] got "11" decimal, which corresponds to v34.11. You could then use OG's CPT instruction to get a REAL that's the major.minor version.
