Adding an operator station

Hello!

I've been running PV 6.1 on single computer setup on Ubuntu 22.04. Meaning that engineering station, operator station and storage are all in one. System is expanding and I'm looking for a way to add one or several operator stations. If new Ubuntu machine is placed on same subnet and should be used as operator station, how I should proceed?

Hi Mika,

Install the pwrrt package on the new operator station.

In the development configuration:

- Register a new volume for the operator station in the global volume list.
- Enter the directory volume and create a RootVolumeConfig object with the same name as the registered volume.
- Also create a NodeConfig object under the production BusConfig object and set node name and IP address.
- Create a RootVolumeLoad object under the NodeConfig object with the same name as the new volume.
- Save the directory volume and open the new volume.
- Configure the volume, and create a MountObject in the plant hierarchy that mounts the object tree in the process station. Don’t forget to configure the OpPlace object and add XttGraph objects.
- Build and distribute to the new operator stations.

You also have to distribute to and restart the process station.

Thank you Claes for detailed instructions!

I'll start working on it.

Now I've done some tests. New operator station is setup with pwrrt package. Also the steps on development station supposed to be done. MountObject, that step I'm not sure if I got it right.

Anyway I tried to distribute but it fails:
Distribute error for node opas2: Distribute command failed!

From development station I can ping operator station (opas2) with IP address. But not with the name, can that be a problem?

Mika,
as you mentionned the nodename isn't in any dns record and the distributor tries to distribute to its dns name. I always create on every node the hosts file (/etc/hosts) so that all the stations are know by every node. With a few nodes this is managable, when having more nodes you 'll have to look out for a dns server.
Also a tip: try to to work with public/private (ssh) keys. This makes the distribution a lot easier. Otherwise you always have to enter the password (twice) by every distribution.

Now I did add records on hosts files and both stations can ping each other with name or IP. But error remains the same.

Designers guide tells about bus identifier (page 148). My new operator station has id 517 but I cannot this identifier anywhere from configuration? They should match, right?
