Simulate a Modbus master and slaves communication

[catarinadf]

Hello,

I am trying to simulate an ICS with the following characteristics:
– (PD6830-AX0-I-2) 1 Modbus scanner to monitor levels and temperature in tanks
– 4 Tank level gauges as slaves (MTS M-Series)
Unfortunately, I don’t know where to start. Should all the devices share the same communication line? What should be the configuration for a Modbus master-slave communication in RapidScada? What is exactly the device template editor and where can I get that information?

Thanks.

Hi,

Please clarify, what are “4 Tank level gauges as slaves”? How do they connected and what protocol use?

What should be the configuration for a Modbus master-slave communication in RapidScada? What is exactly the device template editor and where can I get that information?

I suggest this article http://doc.rapidscada.net/content/en/use-cases/modbus-protocol.html
The template editor is http://doc.rapidscada.net/content/en/use-cases/modbus-protocol-files/modbus_template_en.png

I need a bit more info to help you.

Hello,

I have already looked at those 2 articles. But I still don’t understand since only one device is simulated with an existing device template.
I would like to simulate this ICS : https://www.predig.com/sites/default/files/images/Connections/6830X_FI_Modbus_RS-485_4Tanks-1_Detailed.jpg
How does the master and slaves communicate with the Modbus protocol in RapidScada ?

Thanks.

RapidScada communicates with Modbus devices as well as other programs. Through registers described in the DOCUMENTATION for the device. But through pictures alas no one not able to communicate. You need documentation for the device, the picture you showed.

Rapid SCADA implements Modbus master to poll devices. If you need simulate a Modbus device, you should download an app like this. And then create a Modbus template according to the manual of your controller.
