Thinking now.
Thank you again

Dear manjey73,
Thank you so much. I was tried again to use your template. The result get better. The communication between communicator and relay board was set up. But the status of relay is not changed when i send the commands (standard, binary, string, hexdecimal). Some screenshot are bellowing:

Where is wrong? I did not understand. Can you check it again?
Thank you again

Dear Mikhail,
What converter do you use to connect the module to a computer?
RS485-RS232-USB converter. This converter connects to a computer. The relay board R421A08 was tested by Modbus Poll – MbPoll1 using this converter. Send commands from Mbpoll1, the relay works perfectly. You can see the screenshot:

Now connecting a converter to computer using Communicatore to send commands. Configurations were sent to you. The relay can not work. Some screenshots were taken again:

Hi Mikhail,
Yes, that is a screenshot in the last time that it was configured Modbus TCP. There are some parameters bellow
1.Description:
  R421A08 8 channel Modbus relay module equipped with mature and stable 8-bit MCU and RS485 level communication chip,adopt standard MODBUS RTU format RS485 communication protocol. It can realize 8bit input signal detection and 8bit relay output. It can be used for digital detection or power control occasions.
 2.Features:
  1>.Support Modbus RTU protocol
  2>.Support RS485/TTL UART interface
  3>.Output indicator in multi mode
  4>.Address can be set
  5>.Support input reverse connection protection
  6>.Relay switch output
  7>.Support parameter memory function
 
3.Parameters:
  1>.Item name: 8CH Modbus Relay Module 
  2>.Work voltage:DC 12V
  3>.Baud rate:9600bps
  4>.Set address:0x01~0x3F
  5>.Delay time: 0~255s 
  6>.Load: AC 250V 10A or DC 28V 10A
  7>.Protocol:Modbus RTU
  8>.Interface:RS485/TTL UART
  9>.Control channel: 8channel
  10>.Operating Temperature:-20℃~85℃
  11>.Operating Humidity:5%~95%RH
  12>.Module Size:90*62*19mm
I hope these parameters can help you and me in the further.
Thanks

Dear Mạnjey73,
Thank you for your fast reply.
Do you have an address binding in the Scada database ?
No, I have not any address in the Scada database. How to do this, could you let me know?
Thanks a lot

Dear manjey73,
I can not get the result. I change method of connection of relay board R421A08. It was connected with rapid Scada by Modbus RTU via RS485 to USB converter. Before connection with Rapid scada the relay board R421A08 was tested by ModbusPoll. The relay board is working On/Off perfectly. The screenshot is belowing:
https://ibb.co/7vth4qc
https://ibb.co/SnfS8Dg
Now i configure rapid scada that the Relay board was connected with communicator via Modbus RTU and manage to send commands to relay. But not result too. Something is wrong, where? Could you help me? Some screenshots are bellowing:

Dear Mikhail,
This is the screenshot of communication line state:

Dear Manjey73,
Thank you very much for your reply. But there was no result. Now I’ll show you how The relay board R421A08 is connected to rapid scada:The relay board R421A08 is connected to local network via RS485 Ethernet converter (192.168.1.105, address 1)
So my question is: How can I configure the communicator to send commands ?
Here is the screenshot: https://ibb.co/znfB2H8

Dear Mr. Mikhail.
I want to ask you: Can the Rapid scada send a command to third control device likes “8 channel RS485 Modbus RTU Relay board type R421A08” ?
Does the Automatic Control module help to do this function? If it can so how to configure?
Thanks a lot

Dear Mr. Mikhail Shiryaev and All.
– The fist: Happy Coming New Year 2020 to you and All

.
– The second: The question about rapid Scada.
The software was installed. It is working perfectly. Was tried a Chart plugin. It was Great. Can access a web remotely via internet. Great more. It was made me excited. But the remote communication i can not get. Could you help me to find where is my wrong ? One Desktop PC was installed rapid scada (full Apps) as server, Can see web via No-IP domain.ddns.net/scada. Another PC was installed only Communication App of rapid and connected with Modbus device (electricity meter) via WiFi of local network that was connecting to internet. Can not connect to scada server.
Hope get the answer from You and All soon.
Thanks and best regards

Hi Mikhail. I am new to rapidscada. After some times i could connect my electricity meter to the software. It is working perfectly. The electricity mater can measure many parameters ( u, i, w, va, var, kwh, Hz …). But it can not display real parameter. Could you help me to use the formula for these parameters?
Thanks and best regards
