Do you have device driver like this? How much?

[vkevinv]

For example,

1. Send [“Z” + 0D0A] from PC to the rs232 device, then the device will send back the data [“450” + 0D0A], I need get the real data “450”. How can I get this data?

2. PC don’t need send command to the rs232 device, the device will send the data to the PC Automatically. How can I get this data?

Thanks!

For example:

1. A device with RS232 serial port, send the data to the PC by press the button at the device, and it does not support sending command to return a data.
2. A device with RS232 serial port, if PC send a command [“Q” + \r\n] to it with RS232 protocol, then it will return the real data.
3. A device with TCP/IP port, if PC send a command [“Q” + \r\n] to it with TCP protocol, then it will return the real data.

How to meet the above requirements by RapidSCADA with its settings?

Dear Mikhail,

It is a good thing for the udate. I will try the updated function that fit my requirement first, and then if I have any further more problems in using the Rapid SCADA, I will apply the payable service from you. ^_^

Thanks!

Deal Mikhail,

I have used the code you sent me few days ago, and I also click the “pass to SCADA-Server” button and restart the two services, but the value from channel 901 is still 72896 degree.

Could you help me find out the reason?

Thanks!

Here it is:

Device 901 "WMD-20-1210339", DLL: KpModbus

I did something following your in strunctions. And I click the “pass to SCADA-Server” button and restart the two services. But the temperature values is as the same values as before.

I don’t know why?

[vkevinv]

Dear Mikhail,

Thank you for your quick reply. It is really a very good news from you. I am really looking forward to this function.

But now how can I swap bytes using formulas in SCADA-Administrator application. Could you illustrate the formula for me?

Thanks!

Kevin
