Configuring IRT Communication
Configuring the Receiver
1. Open the property sheet for the IO controller (double-click the corresponding
row in the configuration table in HW Config).
2. Select the "Receiver" tab.
3. Click the "New" button.
4. In the property sheet for the receiver, click the "Assign Sender" button.
5. In the "Assign Sender" dialog box that is displayed, select the data range of the
desired station. This is the data range to be received by the local CPU.
6. Confirm your settings with "OK".
7. In the property sheet for the receiver, enter the start address of the address
area that will be used when receiving.
The length of the address area should not be changed since it will be
automatically adjusted to the length of the sender range.
Note: The configuration can only be compiled if the sender range and the
receiver range have the same lengths!
8. Repeat steps 3 to 7 for additional receiver ranges .
9. Each assigned sender has a diagnostic address reserved for it. The receiver
can detect failure of the sender by means of its diagnostic address.
Click the "Diagnostic Addresses" button to edit these addresses
5.8 Downloading an IRT Configuration
The configuration data must be downloaded to all devices that are involved in IRT
communication.
Before downloading, first perform a consistency check and eliminate any errors
that may exist.
Recommendation
Sync domains are not limited to one station. Download the IRT configuration from
the network configuration (NetPro).
To do this, select the Ethernet subnet and then select the PLC > Download to
Current Project> Stations on the Subnet menu command.
