Assignment of the DB
DB for the FC°CNT_CTRL
All data associated with a channel of the module are located in the DB of FC CNT_CTRL.
The data structure and the length of the DB is determined by the variable declaration in
FC CNT_CTRL. Prior to configuring the module, the DB must have the following valid data
assigned to it (see section "Program (Page 45)"):
● Module address (address 6.0)
● Channel starting address (address 8.0)
● User data length (address 12.0)
The DB was generated from the UDT 1 as a data block with associated, user-specific data
type (see section "Program (Page 45)"). The DB assignments resulting from this are shown
below.
