Setting The "Iid_Hw_Connect" Data Type - Siemens SIMATIC RF650R Configuration Manual

7.4

Setting the "IID_HW_CONNECT" data type

Before you can start parameter assignment of the blocks, you first need to create a variable
of the PLC data type "IID_HW_CONNECT". The Ident system or a channel of the Ident
system is addressed using the "IID_HW_CONNECT" PLC data type.
Addressing the Ident devices
When working with all the instructions/blocks, you require the "IID_HW_CONNECT" data
type to address the reader. Setting the command parameters for the Ident profile is handled
by the Ident blocks. The Ident profile and the "AdvancedCMD" block also require the
"IID_CMD_STRUCT" data type for the parameter assignment of the individual commands.
Depending on whether you work with the Ident profile or the Ident blocks, you need to link in
and assign parameters for these data types as described in the following sections.
Parameter assignment of the "IID_HW_CONNECT" data type
Follow the steps below to set the parameters for the "IID_HW_CONNECT" data type for a
channel:
1. In the project tree, double-click on the entry "Create new block" in the "Program block"
folder.
2. Click the "Data block" button and assign a name to the block.
3. Confirm your entry with "OK".
The data block is opened.
4. Create a new variable by entering a variable name in the "Name" column.
5. In the "Data type" column, select the "IID_HW_CONNECT" data type.

6. Specify the address data of the reader.
– HW_ID: Hardware identifier of the module (with S7-1200 and S7-1500)
– CM_CHANNEL: Selection of read point
– LADDR: I/O address of the module
You can read out the values of the "HW_ID" and "LADDR" parameters in the device
configuration in the properties of the reader. Enter the parameter values you have read
out in the "Start value" column of the corresponding parameters. Reading out parameter
values is described below.
