Explain the need for CP card in the PLC network
A CP card is used for Profibus communication. it can be used to connect with any field device or remote IO modules. it can be used to segregate your Profibus network or segments for instance nodes from noisy areas on their own network
A CP card, (or) Communication Processor card, is an essential component of a Programmable Logic Controller (PLC) system.
The primary purpose is to facilitate communication between the PLC & other devices (or) networks.
Key Functions
- Offloads communication work from the primary CPU.
- Supports different communication protocols.
- Enables connecting to various industrial networks.
Features
- Enhances overall system performance.
- Enables more complicated communication arrangements.
- Enables real-time data interchange.
Advantages
- Improves PLC communication capability.
- Provides flexibility in the system design and facilitates expansion.
Common Applications
- Connecting with SCADA systems
- Interfacing with Human-Machine Interfaces (HMIs)
- Networking several PLCs.
- Integrating with additional industrial equipment.
Supported protocols can involve the following:
Modbus Profibus Ethernet/IP DeviceNet
The CP card improves the PLC’s capacity to communicate & integrate with a variety of industrial systems and networks.
