Example: Changing without multi-instance
To change from a block without multi-instance to Ident blocks/profile, follow the steps below:
1. Delete all previous blocks ("PIB_1200_UID_001KB", "Read", "Write", etc.) and their
instance DBs from the "Program blocks" folder of the project tree.
2. Delete the previous data types "HW_CONNECT_VAR" and "CMD_STRUCT" from the
"PLC data types" folder of the project tree.
3. Drag the required Ident block from the library tab to the open block.
Make sure that you use the name of the old block call again in the new block call (e.g.
"Reset_RF300_DB").

4. Copy the variables of the old block call into the new block all (e.g. using drag and drop).
5. Delete the old block call.
6. Open the data block in which the "HW_CONNECT_VAR" variable was created.
7. Note down the address parameters of the variables.
8. Change the data type from "HW_CONNECT_VAR" to "IID_HW_CONNECT" and enter the
address parameters.
If you have created a variable of the type "CMD_STRUCT", change the data type to
"IID_CMD_STRUCT".
9. Repeat steps 3 to 5 for each created block.
10.Repeat steps 6 to 8 for each channel/reader.
