Follow the steps below to read out the parameter values "HW_ID" and "LADDR" for a
channel:
1. Open the network view and double-click on the communications module.
Reaction: TIA switches to the device view and the properties window of the CM opens.
2. In the "Device overview" tab, select the relevant module.
The I/O address displayed in the tab corresponds to "LADDR".
Note that the input and output address must have the same value.
3. In the "Properties > System constants" tab, you will find the hardware identifier that
corresponds to the "HW_ID".
Figure 3-2
4. Transfer the values of "LADDR" and "HW_ID" to the PLC data type "IID_HW_CONNECT"
of the reader for which you want to set parameters.
Note
Setting the user mode
In the properties of the communications module, make sure that you assign the value "RFID
standard profile" to the "User mode" parameter and select the suitable MOBY mode.
With all other communications modules/readers, you will find the two parameters directly in
the properties of the module.
The "IID_HW_CONNECT" data type has now been created for a channel. Repeat these
steps for every other reader/channel. If you want to use a different channel of the reader/CM,
set this using the "CM_CHANNEL" parameter. The "HW_ID" and "LADDR" parameters
remain the same for all channels/readers/antennas. With an RF18xC communications
module, each reader is assigned to a separate module and has its own "HW_ID" and
"LADDR". Please note that the value of the channel always needs to be "1".
