Figure 28 - Variable properties
You can set properties using Properties component.
There are following properties:
1.
Name
–
name of a variable.
2.
Type
–
type of a variable. Cannot be changed.
3.
Initial value
–
a value that variable has before it is changed due to
signal flow.
4.
Address
–
mapping variables to the PM180 internal variables such
as digital inputs, relay outputs, set points, etc. Local variables
don’t have such set
ting.
Please note that in order to operate on the PM180 device every
input and output variable of FB must be mapped to the device internal
variables otherwise you will get
a message “
Variable address is not set
”
during uploading the configuration to the device.
Be advised that PLC Configurator automatically distributes set points
according to the
device property “Settings range for the logic
generator”.
To set this setting, see
3.4. We discourage you from
mapping output variables to set points, because PLC Configurator does
it automatically anyway. In case of manual mapping output variables to
set points you can get errors concerning execution sequence of function
blocks. In other words, logic that you made in PLC Configurator can be
executed in a different way on the device and the result that you get
will be different.
To set the address, click on icon in the Address setting. Depending
on the type of variable one of the following windows will appear:
