Concept I: Parameterisation through direct instructions in the FBs
For this, use the FB L_8200Parameter as template and create a new function block in which the
parameter data are selected by direct assignments.
Note!
Please observe that FB changes (e. g. new assignments) require a new compilation and program
download to the PLC.
·
If you want to change the parameters "online" via the Parameter Monitor or keypad, use
concept II ("Parameterisation by means of codes").
Tip!
The FB L_8200Parameter already includes commented assignments for all parameters relevant
for frequency inverter control.
·
The parameters are listed in the table on the next page.
·
The names of the inputs and outputs of the FBs L_8200CtrlWord and L_8200StatusWord
have been adapted to the selected parameters.
·
If you want to use the pre−assignments, simply copy the assignments to the new FB and
remove the comment characters so that the assignments will become effective.
·
Of course, it is also possible to adapt the assignments to your application.
Proceed as follows:
1. Create a new function block.
2. Use the Library Manager and copy the source code of the FB L_8200Parameter to the new
function block.
3. Remove the comment characters around the assignments to accept the pre−assignments or
adapt the assignments to your application.
