OPC on Remote PC

[Mikhail]

Hi,
Good! Does the whole system run well for now?

Hi Mikhail,

I can browse the remote OPC server now. I have’t checked the point values yet. I will update here. Thanks.

Hi Mikhail/scadakid,

Could you please make an instruction how to integrate OPC DA/UA remotely?
Also how to add a new instance?

Thank you very much!

Hi,

Please provide more details of you task.
OPC DA and OPC UA are supported by different Rapid SCADA drivers, and they are configured differently.

You also could watch this video about OPC UA configuring.

Hello Mikhail,

1. A computer, IP: 192.168.10.111,
installed: MatrikonOPC Server; ScadaAgent and ScadaComm(of RapidSCADA)
2. B computer, IP: 192.169.10.106,
installed: RapidScada (except of ScadaComm)
Configure:
Common Parameters: server: 192.168.10.111(A computer IP address)
Connection Settings Server: 192.168.10.111
Upload: got “Unable to login – Error validating user

3. copy BaseDat from B computer to A computer
Upload: “Upload competed successfully. Duration:0 Sec. Data size 230383 bytes”

4. A computer: stop ScadaCommservice, then start ScadaCommservice
5. B computer:
Instance–>Default–>Server–>Stats got “File not found”
Instance–>Default–>Communicator–>Communication Lines–>Stats got
connect to SCADA-Server “192.168.10.111”
Error Connecting to SCADA-server: No connection could be made because the target machine actively refused it 192.168.10.111:10000
Disconnect from SCADA-Server
Unable to start operation due to SCADA-Server communication Error

Both A and B computer’s fire wall are off
Port 10000, 10001, 10002, 10010 are opened

What’s wrong?

thanks in advance

On A computer, IP: 192.168.10.111
Edit ScadaCommSvcConfig.xml in the fold: c:\SCADA\ScadaComm\Config

<CommonParams>
<Param Name = “ServerHost” value = “192.168.10.106” (was 192.168.10.111)

Keep all the other the same

stop ScadaCommservice, start ScadaCommservice

On B computer, IP: 192.168.10.106
Instance–>Default–>communicator–>[2]OPC–>[21]OPC Demo
three tags are there, and updating
Instance–>Default–>communicator–>[2]OPC–>Line Stats–>Active Device 1. Device 21 “OPC Demo”: Normal

However:

Instance–>Default–>Communicator–>[2]OPC–>Line Parameters–>Request Sequence–>Properties–>OPC server got “<No available servers>

Should Call Number or host name be 192.168.10.111?

Best Regards

Steven

Workaround solution:

1. Install RapidSCADA fully on both A and B computer

2. On A computer(on which there is OPC server),
a. Create a new communicaiton line
b. Create a new devie
c. Create new Input channels and output channels
d. Create new communication line in Instance

all above can do them according training videos

Local OPC on local server( A computer should work now)

3. repeat the save steps on B computer
or copy all files from A to B (did not test, but must work)

4. copy all the files in the fold SCADA\ScadaComm\Config
from A computer to B computer

5. Stop ScadaServerService on A computer
6. Stop ScadaCommservice on B computer

7. Change Common Parameters (server) to B computer IP address
8. Change Connection Settings (server) to A computer IP address
9. Upload

Done

Hello Steven,

Error Connecting to SCADA-server: No connection could be made because the target machine actively refused it 192.168.10.111:10000

This error is usually caused when firewall of the server machine blocks incoming connections to the port 10000.

I strongly suggest to move from classic OPC DA to modern OPC UA. It works much better in network environment.

[Mikhail]

Both A and B computer’s fire wall are off
Port 10000, 10001, 10002, 10010 are opened

Please check the connection using telnet or any other utility (e.g. Hercules).
Just try to connect via port 10000.

Hello Mikhail,

Thanks for the reply.
I got it work as the posts #8942 and/or #8943….(it’s not TCP/IP ports, it’s IP address)

(It has been notised that there are a lot of posts about TCP/IP ports, would be better the installation execution file can check if those ports are free.)

Thanks again!

Steven
