Which Delta PLC Do You Need?
- For High-Speed Motion (EtherCAT): Use the AX-3 or AX-8 series. These utilize the CODESYS platform, allowing for industry-standard motion programming.
- For IoT & Industrial 4.0: The AS300 or DVP-SE are the best choices due to their native Ethernet ports and easy integration with Delta HMI Cloud functions.
- For Process Control (Analog): Choose the DVP-SX3 or DVP-EX3. Having built-in Analog I/O saves significant costs on expansion modules for sensors and valves.
- For Large-Scale Infrastructure: The AH500 is the only choice for applications requiring “Hot-Swapping” (replacing modules while the system is running) to avoid total site downtime.
Technical FAQ for South African Engineers
Q: Can I use DVP-S series expansion modules on the AS300?
A: No. The AS Series uses a high-speed non-backplane design with different connectors. However, both can communicate over a common Modbus or CANopen network.
Q: Which software is used for these controllers?
A: * DVP and AS Series: Use ISPSoft (advanced) or WPLSoft (basic).
- AX Series: Uses DIADesigner-AX (based on CODESYS).
Q: Are these PLCs “Load Shedding” resilient?
A: All Delta PLCs feature non-volatile memory that retains your program and critical registers during a power failure. For critical data logging, we recommend pairing them with a Delta UPS System.
