Hi,

I am using TCP driver communication in ignition.

Following are the procedures i have gone through for creating the connection and writing to a device using TCP driver.

- Created new TCP Driver device as per inductive automation tutorial and connected the TCP driver as per the image attached 

- After i opened OPC quick client, try to write a message its not writing a message, its showing error.for your reference kindly check the image

- Then i browsed the tag from OPC browser and made the tag writable but it’s not sending the text to the device

- If any port open close condition script is there in ignition?

please help me
