Delta PLC Programming and Selection

Integrated Approach to Programming and Hardware Selection

When selecting a Delta PLC, consider both hardware and programming environment:

• ISPSoft – Delta’s main programming software, supporting LD, FBD, SFC, IL, and ST (IEC 61131‑3). Includes PLCopen® motion control blocks.

• DIADesigner – Supports AS series and DVP‑ES3/EX3/SV3/SX3.

Programming‑related selection criteria:

• Program capacity – AS: 128k steps; AH: 256k steps for complex logic.

• Supported languages – check model compatibility.

• Motion control – choose models with PLCopen® support.

• Debugging interfaces – USB, Ethernet, RS485.

Also consider software ecosystem: Delta PLCs integrate seamlessly with Delta drives and HMIs, and pre‑built function blocks accelerate development. Ouling Engineering offers training and technical support to help you master Delta PLC programming.
