PROSOFT MVI56-PDPS Communication Module
PROSOFT MVI56-PDPS
1. Overview
The MVI56-PDPS is a member of the MVI56 series communication modules from ProSoft Technology. Its core function is to act as a bridge that connects the ControlLogix PLC system to field devices such as sensors and actuators linked via PROFIBUS DP, enabling bidirectional data transmission between these systems.
2. Specifications
The communication interface of the MVI56-PDPS is a Profibus DP Slave. It supports a wide data transfer rate range from 9.6 kbps to 12 Mbps, facilitating high-speed data communication. The module operates within an industrial-grade temperature range, typically from -40°C to +70°C, making it suitable for harsh working environments. Its typical power consumption is approximately 2.5W, with the exact value depending on the supply voltage, which can be either 5V DC or 24V DC. In terms of compatibility, it is designed for single-slot integration with the 1756 backplane and seamlessly works with the ControlLogix I/O system.
3. Key Features
The MVI56-PDPS enables multi-network interconnection by connecting to Profibus DP master devices, thus achieving cross-protocol data communication. Its single-slot design allows for seamless integration with the ControlLogix backplane without the need for an additional power module, simplifying installation and reducing space requirements. The module offers flexible configuration options, supporting ladder logic programming to realize data interaction between the module and the processor through PLC programs. Built with an industrial-grade design, it ensures high reliability, and some models come with an IP67 protection rating, allowing them to adapt to harsh industrial environments.
4. Structure and Components
The ControlLogix backplane connector is used to insert the module into the PLC system’s backplane, providing it with power and enabling communication signal transmission. The Profibus DP interface is a standard port that connects the module to the Profibus network of field devices. The configuration/debugging serial port allows for connection to a PC, which is used for module configuration, status monitoring, and troubleshooting. The status indicator lights display essential information such as the module’s power status, communication status, and fault diagnosis details, helping operators quickly identify any issues.
5. Application Areas
In process control, the MVI56-PDPS is widely used for continuous process monitoring in the chemical, petroleum, and natural gas industries. For discrete manufacturing, it supports the control of discrete equipment in the automotive and electronics manufacturing sectors. It also plays a vital role in factory automation, including applications in heating, ventilation, and air conditioning systems, lighting systems, and security systems. Additionally, it is ideal for equipment upgrading projects, facilitating the modernization of legacy Profibus DP networks and enabling their connection to new PLC control systems.
6. Installation and Maintenanc
Installation
For backplane installation, the module is directly inserted into an empty slot of the ControlLogix 1756 backplane, ensuring that the backplane power supply and network connections are properly established. For DP network connection, Profibus DP cables are used to link the module’s DP port to either the network master or other slave devices, forming a complete communication network.
Configuration
Two main software tools can be used for module configuration: ProSoft Configuration Tool and Rockwell’s Studio 5000 (RSLogix 5000). These tools allow users to set key parameters such as the DP station address and baud rate. To enable data reading and writing, ladder logic programs need to be developed within the PLC program, defining the data interaction rules between the module and the PLC system.
Maintenance
When troubleshooting, operators can first check the error codes displayed by the status indicator lights on the module. For more detailed diagnosis, a PC can be connected to the module via the serial port to access comprehensive fault information. Regular environmental checks are also essential to ensure the module operates within the specified temperature range. It is crucial to avoid exposing the module to high humidity and high-temperature environments, as these conditions can lead to electrical failures and affect the module’s performance and lifespan.
