1. Connessione hardware
Compatible PLC: AB 1769-L23-QB1B
The EtherNet/IP protocol utilizes Ethernet communication. Therefore, simply ensure the gateway’s LAN port and the AB PLC’s IP address are within the same subnet.
2. Parametri di comunicazione del PLC
2.1. Impostazioni dei parametri Ethernet

3. Impostazioni del gateway
3.1. Impostazioni di connessione del PLC
Drag an Allen-Bradley node from the left panel, double-click to open the settings page, and configure as follows based on the PLC’s network port parameters:
Protocollo: Select EtherNet/IP
Indirizzo: Enter the PLC address (e.g., 192.168.1.13)
Porto: Enter the PLC connection port (e.g., 44818)
Timeout della connessione: 2000
Timeout di comunicazione: 2000
Tempo di mantenimento: 60000
Slot: 0
3.2. Configurazione del punto dati
Enter the data points to be read into the parameter list of the Allen-Bradley node. Once configured, the PLC data will be automatically retrieved at the specified frequency.
I punti dati sono tipicamente forniti dai tecnici del PLC. Una volta ricevuto l'elenco dei punti, è necessario compilare i punti dati secondo il formato richiesto dal gateway. Per dettagli specifici sulla mappatura, consultare:

This example reads data from addresses XT and XT1. In the parameter list, enter the address/name/data type/data length in sequence. The data is read cyclically every 2 seconds, as shown in the figure:
3.3. Test
Click Deploy and observe that a data point is printed every 2 seconds. The read data point results are: XT:true, XT1:5. Communication successful!
