The ProSoft PTQ-PDPMV1 is a PROFIBUS DPV1 Master Interface Module designed exclusively for Rockwell Automation ControlLogix 5570/5580 and CompactLogix 5370/5380 processors. It enables these Logix-based controllers to act as a PROFIBUS DPV1 master, facilitating seamless communication with PROFIBUS DP slave devices in industrial automation systems.
The PTQ-PDPMV1 is a single-slot module that installs directly into the local or remote chassis of ControlLogix/CompactLogix 5570+ systems, leveraging the Logix backplane for high-speed data exchange with the host processor. As a PROFIBUS DPV1 master, it supports both cyclic (real-time process data) and acyclic (configuration, diagnostics, and parameter) data transfer, making it suitable for integrating legacy and modern PROFIBUS devices into Logix-controlled environments without custom programming.
- PROFIBUS DPV1 Compliance: Full support for PROFIBUS DP-V1 protocol, including cyclic data exchange (DPV0) and acyclic services (DPV1 Class 1/2). It also supports PROFIBUS DP commands like Sync/Freeze for coordinated control of slave devices and PROFIdrive 4.0 compliance for seamless integration with variable frequency drives (VFDs).
- High Slave & Data Capacity: Can manage up to 125 PROFIBUS DP slave devices (with or without repeaters) and handle up to 2048 bytes of cyclic input data and 2048 bytes of cyclic output data, meeting the demands of large-scale industrial applications.
- Native Logix Integration: Communicates with the host Logix processor via Producer/Consumer (CIP) technology, eliminating the need for proprietary drivers. It appears as a standard I/O module in Studio 5000, allowing configuration and data mapping directly within the Logix project environment.
- Simplified Configuration: Set up using ProSoft Configuration Builder (PCB) software, which offers a user-friendly interface for defining slave device lists, configuring bus parameters (baud rate, address), and importing GSD files. The module also supports online diagnostics and parameter editing for connected slaves.
- Robust Redundancy: Optional support for ControlLogix Redundant System (1756-RM series redundancy modules), ensuring continuous operation and minimal downtime in mission-critical applications where system reliability is paramount.
The PTQ-PDPMV1 is widely used in industries requiring integration of Logix controllers with PROFIBUS DP devices, such as:
- Process Automation: Connecting ControlLogix/CompactLogix systems to PROFIBUS-based sensors, valves, and transmitters in oil & gas, chemical, and pharmaceutical plants.
- Factory Automation: Integrating PROFIBUS DP slaves (e.g., servo drives, motor starters, and vision systems) into Logix-controlled production lines for automotive, electronics, and packaging industries.
- Legacy System Upgrade: Enabling modern Logix controllers to replace outdated PLCs while retaining existing PROFIBUS DP infrastructure, reducing upgrade costs and downtime.
- Motion & Drive Control: Using PROFIdrive 4.0 support to control and monitor PROFIBUS-enabled variable frequency drives (VFDs) and servo motors directly from the Logix processor.
