It works perfectly changing to 1 second delay and restarting PC.

Thanks!

Mikhail, you told in post #187 “Data refresh frequency that equals 0 works within schemes but does not work within table views.”

I would like if the same problem occurs with events. I have set Event refresh frequency to 0, but when I run SCADA-Web, the events don´t refresh automatically. It only refresh if I refresh the entire page pressing F5 or similar.

I have tried to set the refreshing time to 1 and 2 seconds, but it still doesn´t work.

What is the problem?

[teleco]

Now it functions very well, I changed the value to 50 ms. The protocol is TCP/IP.

Sincronously and fluently.

[teleco]

Yes, the CPU load is 100% the whole time I am receiving data from OPC server. But, setting the delay to 50 ms, the result stais practically the same, however, the sincronization reduces significantly. I have to say, that my PC hardware is not very powerfull.

[teleco]

Full sincronization achieved!

Sincornization OPC Server and SCADA-Communicator:

– In SCADA-Communicator -> Line 2 “OPC” -> Communication Line Parameters tab -> Communication parameters -> Delay after request cycle,ms = 0
– In SCADA-Communicator -> Line 2 “OPC” -> Request Sequence tab -> Select the OPC device -> Delay = 0
– In SCADA-Communicator -> Line 2 “OPC” -> Right click on the device -> Properties -> Select the read data folder created which contains the signals -> Update rate, ms = 0

Sincronization SCADA-Web and SCADA-Server:

-In SCADA-Web Configurator -> Application tab -> Data refresh frequency, sec = 0

Doing the previos, I reached no delay between the OPC Server and SCADA-Web.

Perfect!!!! Sincronization OPC Server and SCADA-Communicator is totally solved.

It remains to solve the delay SCADA-Web with SCADA-Communicator. As I told before, the dinamyc pictures changes with delay respect to SCADA-Communicator signals.

[teleco]

I can’t find “Update rate field for a data group”. In Device popup menu there is not any kind of rate field. The only fields I see for read data in device configuration form are: name, path, active checkbox, is array checkbox, channel and signal.

I have noticed that the delay is composed by two delays: one between the server and SCADA-Communicator and the other between SCADA-Communicator and SCADA-Web.

Respect to SCADA-Web I have created a dinamyc picture that appears or desappears depending on the value of a boolean variable (1 or 0), so, when SCADA-Communicator changes in some variable, the respective picture changes its status but with some delay.

The server receive the signals from a simulation device software. Then I connect SCADA-Communicator to the server and finally I open a Quick client (server tool) connected to the server which shows me the signals from the simulation.

The quick client values changes simultaneously to the simulation software, but the values showed in SCADA-Communicator changes with delay. I have checked the options of the server and I select the scan mode: Respect client specified scan rate, so there should not be any kind of delay.

The server I use is Toolbox OPC Power Server 5.16.

I have defined an output channel and I have specified “Off – On” in “Command values” field. I need to send an 0 or 1 to the “Command number” indicated, but when I select Off or On in SCADA-Web, it doesn´t send any of these values.

Which kind of formula do I have to use in order to send an 1 selecting On and to send 0 selecting Off. How can I make the relationship 1-On and 0-Off?

In order to make some checking, when I send a command with the SCADA-Server Generator, the Stats log says:

Command 0x06 (command) is received from the client…

The answer is the same selecting either 0 or 1.

I don´t know how to proceed.

[teleco]

In automatic control module is available a trial period. Could you provide the same option to charting component?

[teleco]

Perfect, tow more questions:

1.- Why KpOpc.dll or KpSms.dll have not any template associated? Button “Properties” in SCADA-Communicator -> Device Libraries does not fucntion.

2.- If I open KpOPC_021.xml it shows the next:

<?xml version=”1.0″ encoding=”utf-8″?>
<KpOpcConfig>
<Params>
<Param name=”ServerPath” value=”Matrikon.OPC.Simulation/{f8582cf2-88fb-11d0-b850-00c0f0104305}” />
<Param name=”DaSpecification” value=”Data Access 3.00″ />
</Params>
<DataGroups>
<DataGroup name=”Demo” active=”true” updateRate=”1000″ deadband=”0″>
<DataItem name=”Saw-toothed Waves.Real8″ path=”” active=”true” isArray=”false” arrayLen=”1″ cnlNum=”0″ />
<DataItem name=”Triangle Waves.Real4″ path=”” active=”true” isArray=”false” arrayLen=”1″ cnlNum=”0″ />
<DataItem name=”Triangle Waves.Int2″ path=”” active=”true” isArray=”false” arrayLen=”1″ cnlNum=”0″ /> </DataGroup>
</DataGroups>
<EventGroups />
<Commands />
</KpOpcConfig>

Could you explain the bold parameters?

[teleco]

Why do yo say that? Is often the server breakdown?

[teleco]

So, as I understand. Scada-Communicator receive some data from address A, with the help of the template, it associates address A with signal B, in SCADA-Administrator is specified signal B as channel C, and finally SCADA-WEB shows the data C (modificates by formula or not).

Now, in your example, t4_max is an signal received from the device, but, supposing I want to setup t4_max as an automatic response to the device in order to cool it (for example) sending a command throught Resett4_max, could I write a formula in Formula field of input channel 104 (t4_max), something like this:

If t4>t4_upperLimit then send 1 to t4_maxOutputChannel

My idea is when t4 channel is higher tan the specified upper limit for it, then the input channel t4_max sends 1 (ON) to its output channel associated (11 in this case) in order to, the output channel Resett4_max send 1 (ON), throught command number 5, to the fan of the device.

Is possible to write a formula which does it?

[teleco]

Call number = localhost:502
The same with localhost, pcname, 127.0.0.1 with and without 502

Every time I change the “call number” in Request Sequence, I press the apply button and then the Restart SCADA-Communicator service button. I don´t know what is the problema. I use the Modbus simulator from http://www.plcsimulator.org/downloads, which doesn´t need any kind of installation or setup.

Communication Line Log tab:

2015-02-01 12:52:13 Communication session with Device 11 “ADAM-6015 Server room”, type: KpModbus, call number: MANUEL
Establish a TCP connection with MANUEL
Error establishing TCP connection: An invalid IP address was specified.

2015-02-01 12:52:13 Communication session with Device 11 “ADAM-6015 Server room”, type: KpModbus, call number: MANUEL
Attempt to establish TCP connection can not be earlier than 5 seconds after the previous

Thank you very much Mikhail for solving my problem, now I can connect to the server and see the control center in my web browser. But still, I would like to know how to change passwords and user names, in order to make the connections… I thought that it is in Scada Administrator, in the Users template, is it?

On more question, once I have logged to some account, when I try to visualize the default scheme, the next error appears:

WCF service error: [HttpWebRequest_WebEXception_RemoteServer]
Argumentos: NotFound
Las cadenas de recursos de depuración no están disponibles. La clave y los argumentos suelen proporcionar suficiente…
