Creating blocks
Requirement
The "IID_HW_CONNECT" data type has been assigned parameters.
Follow the steps below to link in a block and to set the call parameters:
1. Open the program block you have created by double-clicking in the "Project tree >
Program blocks" tab.
2. Drag the required block from the block library tab to the program block.
3. Enter the variable you created earlier in the "HW_CONNECT" input parameter.
The block is called and connected to the relevant channel.
Note
Working with multiple channels
If you work with several channels, you must ensure that for each channel, the block is called
with a separate instance DB.
Note
Working with the Ident profile or with the "AdvancedCmd" block
If you work with the Ident profile or with the "AdvancedCmd" block, you also need to connect
the "CMDREF" input parameter with a variable of the "IID_CMD_STRUCT" (Array [1...n])
data type.
