1. Ligação do hardware
Compatible PLC: AB SLC 5/05
The PCCC 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. Parâmetros de comunicação do PLC
2.1. Ethernet Parameter Settings

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 PCCC
Endereço: Introduzir o endereço do PLC (por exemplo, 192.168.0.59)
Porto: Enter the PLC connection port (e.g., 44818)
Tempo limite de ligação: 2000
Tempo limite de comunicação: 2000
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 address F8:1. In the parameter list, enter the address/name/data type/data length sequentially. The data is read cyclically every 2 seconds, as shown in the figure:
3.3. Ensaios
Connect to the debugging node, click Deploy, and observe that a data point is printed every 2 seconds. The read data point result is:
{F8:1:42669}. Communication successful!
