ProSoft PTQ-PDPS Slave Communication Module

1. Basic Specifications
Model: PTQ-PDPS
Brand: ProSoft Technology
Compatible PLC: Schneider Modicon Quantum series PLC (Unity Pro software)
Core Function: PROFIBUS DP V0 slave communication module
Function: Virtualizes the Quantum PLC as a DP slave, enabling integration into third-party PROFIBUS DP master systems (such as ABB AC800PEC, Siemens S7, ABB REC670 protection relays, and drive controllers), thus facilitating data exchange across different brands of PLCs and devices. 。
Series Differentiation (to avoid confusion)
PTQ-PDPS: DP Slave (this model, PLC acts as slave for external master station read/write)
PTQ-PDPMV1: DP Master (PLC acts as master, connecting field instruments and inverters)

Hardware Interfaces
PROFIBUS DP Interface: Standard 9-pin DB9, bus terminal block, baud rate 9.6k–12 Mbps
Debug Serial Port (RS232): Dedicated configuration port, connects PC to module for configuration download and online diagnostics (debug cable included as standard)
Backplane Bus: Power supply from Quantum rack backplane at 5 VDC, backplane current 1100 mA
Status LEDs: Power, Ready, Bus Error, Communication status indicators

Communication Core Parameters
Protocol Standard: PROFIBUS DP V0, compliant with IEC 61158; GSD file required for import into DP master
Cyclic I/O Data Capacity
Input (Master → PLC): Up to 244 bytes
Output (PLC → Master): Up to 244 bytes
Total bidirectional real-time exchange area: 400 bytes
Slave Address Range: 3–125 (addresses 0/1/2 reserved for master, not available)
Data Mapping: Customizable mapping to Quantum registers
Input data → PLC 3x register (%IW)
Output data → PLC 4x register (%QW)

Key Features
Independent Data Buffer: Module locally caches DP bus and PLC backplane data, ensuring no mutual blocking
Complete Fault Diagnosis: Detects bus disconnection, address conflict, module failure, register overflow alarms; supports uploading PLC programs
Configuration Persistence: Parameters downloaded and stored locally on the module; communication reconfiguration not needed when replacing CPU
Industrial Temperature Range: Operating 0–60°C, storage -40–85°C, humidity 5%–95% non-condensing
Certifications: UL, CE industrial certifications; suitable for power plants, metallurgy, and drive control cabinets
