Dear Experts,

I have connected my all PAC 3200 meters on Modbus TCP/IP communication.

I have to turn on PAC 3200's digital output from SCADA.

I have used 60008 address to turn on digital output but it is not working.

Need help in it!

Thanks & Regards,

60008

In your SCADA, can you specify the function code that is used for the telegram?

Can you read different data from the PAC3200?

Dear Gwawl,

Yes, I can read different data from PAC 3200.

The only problem is i am not able to turn on my output through scada.

I have used 60008 offset which is given in manual page no. 61

Thanks & Regards,

Dhaval Abotiyawala.

Are you using function code 6?

Does the SCADA return an error code when you try to write the output?

Dear Gwawi,

Yes I use function code 6. I used 6x60008 address for digital output. I have attached screen shot.

SCADA is not returning error code.

It shows me it is not connected when i observe this tag in I/O field (i.e yellow triangle with exclamation mark)

All other data is coming from PAC 3200 .

Thanks & Regards,

Dear Dhaval Abotiyawala,

have you tried it with a different data type? Normaly with function code 6 you write one holding register. You specified it as Binary Tag. I don't know if that makes a difference.

Dear Gwawl,

Yes I tried it with different data types. Still not able to turn on output.

Are I using wrong address of register or function code?

Thanks & Regards,

Dear Dhaval Abotiyawala

I think you are using the correct address and function code.  And I don't know why it does not work. Perhaps you should open a service request about that issue.
