TCP Device Bad_ReadOnly: User does not have permission to perform the requested operation

[hulla]

I am trying to test TCP device. Plan is to connect various scales via TCP to RC232 converter. I have Moxa nPort connected to a loop on RS232 side. When I connect via telnet I say Hello and I recieve Hello.

I created TCP device set IP and port and 1/1 CONNECTED

From now on, not much seems to work. I have set the device to be writable but the tag

[default]Devices/TCPTest1/4001/Writable

is empty. I do not know why.

[default]Devices/TCPTest1/4001/Message

Error writing to Message: Bad_ReadOnly: User does not have permission to perform the requested operation.

But all the permissions seems OK, I have only one opcuauser who has all the permissions.

I wanted to test how can I control the communication flow etc, but I cannot get to the basic operation.

is there any more detailed doc than UDP and TCP Driver | Ignition User Manual

Writable is empty. I do not know why.

Because you need to write to it. Incoming data arrives in Message (readonly). You respond to the Writable tag with your outgoing data.

(Or use the *Bytes tags if your messages aren't ASCII.)

Thank you!
