1. Ligação do 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.

3. Definições da porta de entrada
3.1. Definições de ligação do 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:
Protocolo: Select EtherNet/IP
Endereço: Enter the PLC address (e.g., 192.168.1.13)
Porto: Enter the PLC connection port (e.g., 44818)
Tempo limite de ligação: 2000
Tempo limite de comunicação: 2000
Keepalive Time: 60000
Slot: 0
3.2. Configuração do ponto de dados
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.
Os pontos de dados são normalmente fornecidos por engenheiros de PLC. Ao receber a lista de pontos, preencha os pontos de dados de acordo com o formato exigido pelo gateway. Para obter detalhes específicos de mapeamento, consulte:

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. Ensaios
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!
