Hi Mikhail, first of all I want to thank you for your support to rapid scada users it’s fantastic! I’m happy to spend my money on a program developed by such dedicated people.
Anyway I created a new line as “TCP SERVER SLAVE” with a device “KpModbusSlave.dll”, I tried to create the output channels with the dll file but I get a programming method equal to the one I did to read data from other modbus devices, equal to “KpModBus.dll”. I would like my datalogger with IP address 192.168.0.40 and with modbus ID 1 to read the data of the various input channels of rapid scada, but to do so it asks me in addition to the IP address and port of the server, the address of the device (from 1 to 247) and the number of the register. In addition to not finding this data, the device I created as a tcp server slave does not read any value from input channels…

I attach, as you asked, the photos of my configurations so that you can better understand my problem.

Hi, how did you do it? I downloaded the modbus slave driver trial because I have to transmit a 0 – 1 signal from a SCADA input channel to a datalogger via modbus TCP to control its relays but for now I have not succeeded… Furthermore I have no idea what modbus address to give to the datalogger to be able to read the data from SCADA, and what modbus ID does Scada have? I don’t understand anything… I looked for answers on the forum but I found nothing

Please help me

Thanks Mikhail, I will try this way.

Here are screenshots of the inputs page, the units page, and the device page from which I read data.

Hi Mikhail,
I did as you said following the HelloWorld project settings but now the word shown does not correspond to the input status, it does not change and appears silver.
Does Scada automatically associate the value 0 with the first word inserted in the units and 1 with the second? I can’t understand how it works…

Hi Mikhail,
I have a channel where I am receiving two values, 0 and 1, and I would like to display the words “normal” and “low”. Therefore, as you wrote, I created the sign -; normal; low; and I made the following formula:`double MyFunc()
{
switch ((int)Cnl)
{
case 0:
return 1;
case 1:
return 2;
default:
return 0;
}
}`
I set the channel to “calculated real”, inserted into the formula field “MyFunc()”, formatted “enum text” and the unit I created as the unit. The problem is that on the server the words alternate regularly displaying – then normal then low and so on ad infinitum even though the channel value is always 0.

I believe the issue is with the amount of digits of the number of registers. In my case the register number is 300002 but rapid scada doesn’t get to this register? Why?

Hi, I can’t get the correct values from a datalogger via modbus TCP. The data logger manufacturer sent me a program to test communications via modbus and it generates this command: 12 34 00 00 00 06 01 04 00 0E 00 02, while rapid scada generates this command: 00 01 00 00 00 06 01 03 00 0E 00 02. What should I do? I’m sorry but it’s the first time I work with a scada program and I always have problems in the modbus configurations… In the links the various photos of the configurations.
