Using the Backend

To use the backend open the HMI in your browser by opening http://127.0.0.1 (replace 127.0.0.1 withe the IP or hostname of your PyScada server) and sign in with your admin account (TODO link to createsuperuser doc).

After successful login in your see the view overview, to open the admin panel click on the Admin Icon.

Now you are in the backend or Admin panel.

Add a new Device

To add a new device (e.g. a PLC) open the Device Table in the PyScada Core section.

You will see a empty list, click on add device in the upper right corner to add a new device (e.g. a modbus device).

We assume we want to add a modbus TCP/IP device (the device act as modbus server, while pyscada act as client). The invormation related to the modbus device will be set in a seperate table. Go to the Admin overview and select Modbus device from the PyScada Modbus Master/Client section.

You will see a empty list. Click on add modbus device in the upper right corner to add a new device (e.g. a modbus device).

For Modbus IP only the IP-Address, the port of the modbus server and the unit id are required.

Add a new Variable

Adding a new variable/data point first add a new Variable entry to Variables table in the PyScada Core section of the admin panel, to do so click add variable in the upper right corner.

A Variable has a name and a description, assign the Variable to a Device and select a Unit of measurement (TODO add description off adding a new unit), activate writable if the value should be changed from the HMI, if the value has to be scaled in order to be displayed right select the right scaling (TODO add description for adding a scaling).

The value_class is the data type in witch the value is represented on the Device (TODO add example). The cov_increment is the amount of change of the value to be stored in the database.

We assume we want to add a modbus variable. To add the information about the register and the function code, add a new modbus variable, to do so open the Modbus variables table from the PyScada Modbus Master/Client section and click add modbus variable in the upper right corner.

Select the Variable to assign by clicking on the magnifier symbol or writing the id of the Variable. Add the register address of the lowes word (a FLOAT32 variable on two 16 bit registers 1234 and 1235, 1234 has to be selected ), for boolen values provide the address of the bit. For the Function code read the function code for reading the value from the modbus server has to be selected, for writing values to the server the coresponding function code will be selected automaticly (TODO function code table).

short instructions for the HMI

In the Backend HMI Section (http://IP/admin/hmi/): 1. Charts, add a new Chart 2. Page, add a Page 3. Widget, add a Widget, select under Page the page you added in 2. and under Chart the Chart from 1., a widget controls the position of every element on a Page. 4. View, add a View and select the page from 2. 5. GroupDisplayPermissions, add a new GroupDisplayPermission, (if nessesary add a new Group and add your User to that Group, select all items you created in 1. to 4. 6. open http://IP/, you should see the new View, if the DAQ is running and there is Data already in the DB, you should see the last 2 Houers of Data and the curennt Data.
