Hello
We have 2 CU's in one project .One CU gets the infeed ready signal through CU input and i want to transfer the signal to the second CU.
I was thinking to transfer the signal through PLC through PZD12. but how can we connect this signal to the parameter P864.
Can anyone guide me 

Regards

Anoop

Hi Anoop,

Use the CU Telegram CU_STW1 Bit 2 is normally free. 

Hope this helps
