Number of decimals – Defines how many decimals to use for this point.
Valid range – defines minimum and maximum value for a write parameter. If a user
tries to enter a value outside the range, a warning message will appear.
Example of creating a custom device template for an unsupported drive:
You have an ABB drive that is not supported by SREA-01. The drive has, however,
Modbus support. You want to log actual values 1.02 SPEED and 1.06 POWER.
1. Create a new device template. Name it according to your drive model.
2. Add a parameter group. You can name the group as Operating data, for example.
3. Add a parameter to the newly added group. Name the parameter as 1.02 SPEED
[rpm]. Configure the parameter as a holding register and define its address to
102. Use unsigned 16 bit data type. The speed is not scaled, so the other defaults
are good.
4. Add another parameter to the group. Name the parameter as 1.06 POWER [kW].
Configure the parameter as a holding register and define its address to 106. Use
signed 16 bit data type. The power is stored in the drive with a precision of 100
Watts, so define the scaling to be 10. Other defaults are good.
5. You can now go to the Devices page and add a new drive of this type.
Refer to the drive firmware manual and possibly to the Modbus adapter manual for
more information on the parameter types and settings.
When you are finished with the Template, continue to the Device Configuration.
