Assignment of the DB
10.1
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 39)"):
• 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 39)"). The DB assignments resulting from this are shown below.
