Delta PLCs support multiple communication protocols to connect easily with other industrial devices like HMIs, sensors, drives, and SCADA systems. These protocols allow smooth data exchange and control across automation networks. Delta designs its PLCs with flexible communication options so they can work with both Delta products and third-party systems.
The most commonly used communication protocol in Delta PLC is Modbus, which includes both Modbus RTU (serial communication) and Modbus TCP/IP (Ethernet communication). Modbus RTU is used over RS-232 or RS-485 ports and is widely used for connecting Delta HMIs, temperature controllers, and inverters. Modbus TCP/IP, on the other hand, is used for high-speed Ethernet-based communication between multiple devices, allowing real-time monitoring and control.
Another key protocol supported by Delta PLCs is EtherNet/IP, which is used in many modern automation networks for connecting PLCs, HMIs, and industrial robots. Delta’s advanced PLC series such as the AH Series and AS Series support EtherNet/IP for fast and reliable communication.
CANopen is another protocol available in some Delta PLC models. It is mainly used for motion control applications, such as connecting servo drives, sensors, and actuators in precise synchronization. For Delta motion systems, DMCNET (Delta Motion Control Network) and MECHATROLINK-II are also supported, providing high-speed communication between Delta PLCs and servo drives for coordinated motion control.
Delta PLCs also support Profibus-DP and DeviceNet, which are popular fieldbus protocols used in larger automation networks and with equipment from other manufacturers. These communication standards allow Delta PLCs to integrate into existing industrial systems easily.
In summary, Delta PLCs support a wide range of communication protocols including Modbus RTU, Modbus TCP/IP, EtherNet/IP, CANopen, DMCNET, MECHATROLINK-II, Profibus-DP, and DeviceNet. This versatility makes Delta PLCs suitable for various automation applications such as machine control, process management, and factory networking, ensuring seamless data exchange and high-speed performance in modern industrial systems.
