13.5.6.3.10 OB 1 - Create instance write parameter
With the FB 880 - VMC_WriteParameter_RTU you have write access to the parameters
of an inverter drive, which is serially connected via Modbus RTU. For the data you can
use the DB created for read access - here DB 98.
1. Add a Call FB880, DB880 to OB 1.
ð
The block call is created and a dialog opens to specify the instance data block
‘VMC_WriteParameter_RTU’ .
2. Confirm the query of the instance data block with [OK].
3. Specify the following parameters:
Call FB880, DB880
