Programming Software for Delta DVP28SV11T2 (SV2 Series)

This unit belongs to second-generation DVP-SV2 PLC; two official software packages are supported:

1. ISPSoft (Recomendado para nuevos proyectos.)

Última versión: V3.24 and above

Mandatory companion: COMMGR communication manager, handles serial/USB communication connection

Supported IEC61131-3 languages: LD (Diagrama de escalera), CALLE (Structured Text), ETA (Diagrama de bloques de funciones), SFC (Gráfico de funciones secuenciales); full SV2 motion instructions, interpolación, posicionamiento de alta velocidad; modular POU programming, simulación, online monitoring, actualización de firmware.

OS: Win7/10/11 (64-poco)

2. WPLSoft (Legacy software for existing project maintenance)

Versión: V2.52, traditional Delta DVP programming software, mainly supports ladder diagram and instruction list, no Structured Text support

Suitable for reading backup programs from legacy equipment and simple logic; inferior to ISPSoft for complex motion-control functions.

⚠️ Note: DIADesigner does NOT support DVP28SV11T2. DIADesigner is for high-end SV3, AS/AH series PLCs.

Programming Cables

For the front-panel Mini-DIN8 RS232 port of DVP28SV11T2:

1. Delta original USB-DVP programming cable (USB to Mini-DIN8)
2. RS232-to-Mini-DIN8 cable is also acceptable; program download is available via COM2 RS485 as well.

Software Selection Guidance

Posicionamiento de servos, interpolación circular, procesos complejos: ISPSoft + COMMGR

Legacy equipment with WPLSoft-format project files: Maintain with WPLSoft.

Communication Protocols for Delta DVP28SV11T2 (SV2)

On-board hardware: COM1-RS232 (Mini-DIN8), COM2-RS485 terminal block. No native Ethernet or CANopen; fieldbus functions require left-side expansion modules.

Protocols Supported by On-board Serial Ports

1. Modbus RTU / Modbus ASCII (Más utilizado)

Available on COM1(RS232) and COM2(RS485); supports both Master and Slave modes

Max baud rate 115200bps; configurable data bits, paridad, bits de parada

Aplicaciones: Connect to HMI, inversores, servos, meters and third-party Modbus devices.

2. Delta proprietary protocol (PLCLink)

Data exchange among multiple DVP-SV2/SA2/SS2 PLCs via RS485 networking.

3. Program download protocol

COM1 RS232: ISPSoft/WPLSoft program upload/download, online monitoring

Program download and monitoring are also supported over COM2 RS485.

Factory default serial parameters: 9600, 7, mi, 1 (9600bps, 7-data-bit, even parity, 1 bit de parada)

Additional Fieldbus Protocols via Left-side High-speed Expansion Modules (Hardware add-on only, not built-in)

Use the dedicated left-side high-speed slot with corresponding communication modules:

DVPCOPM-SL: CANopen master module, CANopen DS301 compliant, for CANopen servo/drive connection

DVPNET-SL: módulo ethernet, supports Modbus-TCP (Master/Slave)

DVPDP-SL: Profibus-DP slave module

DVPDNM-SL: DeviceNet module

Port Function Summary

Errores comunes

1. DVP28SV11T2 has no built-in Ethernet or CAN interface. Expansion modules must be purchased separately.
2. COM1(RS232) can only operate as Modbus Slave. Modbus Master function is exclusively for COM2(RS485).
3. PLCLink works only between Delta DVP-series PLCs; incompatible with third-party hardware.

Complete Installation Guide for Delta DVP28SV11T2 (ISPSoft + COMMGR)

ISPSoft is preferred for DVP28SV11T2(SV2). COMMGR is mandatory for communication; program download will fail without it.

SO compatible: Win10 / Win11 64-bit. Download installation packages from Delta Industrial Automation official website.

Preparación previa a la instalación

1. Uninstall old versions of ISPSoft and COMMGR; mixed versions cause communication failures.
2. Right-click installer → Run as administrator (critical for Win11; avoids installation errors and driver failure).
3. Temporarily disable antivirus / Windows Defender to prevent component interception.
4. Ensure .NET Framework4.5 is installed (included in modern Windows; download from Microsoft if missing).

Two Installation Procedures

Method A: COMMGR bundled inside ISPSoft installer (Recomendado)

1. Unzip ISPSoft archive and run Setup.exe.
2. Select Chinese language, follow on-screen prompts; keep the [COMMGR] component checked, do not uncheck it.
3. Customize install path; avoid Chinese-character directories on C drive (p.ej. D:\Delta\ISPSoft).
4. Complete installation and reboot PC as prompted.

⚠️ If COMMGR was unchecked during setup, download and install COMMGR separately.

Method B: Separate installation

1. Install COMMGR (Communication Manager) first.
2. Install ISPSoft programming software afterwards.

Post-installation Configuration (Program editing ≠ download capability; COMMGR channel setup is required)

1. Close ISPSoft first, launch COMMGR from start menu (icon appears in system tray).
2. Click [Agregar]

Driver name: English characters only, p.ej. DVP_SV2 (No Chinese characters or spaces)

Tipo de comunicación:

Delta USB programming cable: Select USB

USB-to-RS232/485 adapter: Select Serial Port, confirm COM number in Windows Device Manager.

3. Parameters matching PLC factory defaults: 9600, 7, mi, 1, Station No.1
4. Confirm configuration, select this channel and click [Comenzar]. Status START means channel is ready.
5. Open ISPSoft, create new project, seleccionar modelo: DVP-SV2 → DVP28SV11T2
6. Menú [Herramientas] → [Configuración de comunicación], select the pre-configured COMMGR channel to go online, upload or download programs.

Alternative Legacy Software WPLSoft (For maintenance-only)

No recomendado para nuevos proyectos.; lacks ST language and advanced motion interpolation instructions.

1. Install WPLSoft V2.53, run as administrator.
2. WPLSoft also relies on COMMGR; communication configuration follows identical steps above.

Solución de problemas comunes

1. Gray online button: COMMGR is not running, channel status is not START.
2. COM port not found: Install driver for USB-to-serial chip (CH340 / FT232); no yellow exclamation marks in Device Manager.
3. Win11 installation errors: Always run as administrator, avoid Chinese-character install paths, disable security software temporarily.
4. Communication errors: Double-check baud rate, parity setting and PLC station number. SV2 factory setting: 9600-7-E-1

Hint for New DVP28SV11T2 Project

ISPSoft New Project → Series DVP-SV2 → select DVP28SV11T2. The software automatically applies hardware parameters: 30K-step program capacity, 4-eje de salida de pulso de 200 kHz.
