Modbus description

We need to ask the PLC programmer for a table containing the addresses of the control panels and the device addresses belonging to the control panel, as well as the treatments and which bits are associated with them.
We cannot import this, you must manually create all data points and their associated treatments.



Create a new container, give it a name, then select Modbus from the list and then the corresponding Protocol.

Host IP: Control panel IP
Default Port: 502
Save the container.




We need to create 3 specific data points within the container. One contains the devices, the other contains the register. The register contains the range from which the Siwenoid should query the status of the devices.
Create a data point of type "TYPE_PHYSICAL_CONTAINER", name it as Physical Container, and then a data point of type "TYPE_PHYSICAL_DATAPOINT". This will be the register, you will aslo need to specify 2 parameters and start-end-range.
Siwenoid will search for devices within this range.
In the table, the range of the first NIB runs from 40011 to 40038.
