Setting parameters for blocks
3.5 Programming the Ident profile
Example: Changing with multi-instance
To change from a block with 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. Open the data block in which you use a block as a multi-instance.
4. Change the data type of the multi-instance:
– With a PIB block (e.g. "Read")
– With "PIB_1200_UID_001KB"
5. Open the data block in which the "HW_CONNECT_VAR" variable was created.
6. Note down the address parameters of the variables.
7. 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".
8. Repeat steps 3 to 5 for each created block.
9. Repeat steps 6 to 8 for each channel/reader.
