Communication Challenges in Malaysia Automation Projects
In automation system integration projects across Malaysia, it is increasingly common to combine equipment and control components from multiple suppliers. PLCs, sensors, remote I/O modules, pneumatic actuators, and other devices may come from different brands and use different communication standards.
This creates a practical integration challenge at the control level. When pneumatic devices use limited or incompatible communication interfaces, additional gateways, conversion modules, or independent wiring may be required. As the number of devices increases, system architecture can become more complex and more difficult to commission.
Why Multi-Vendor Automation Systems Are Difficult to Integrate
Traditional pneumatic control systems often rely on individually wired solenoid valves or valve groups with limited communication options. This structure may be sufficient for smaller machines, but it becomes less efficient when several subsystems must operate together.
In multi-station automation systems, controllers need to exchange status and control data quickly and consistently. Different interfaces, additional wiring, conversion devices, and separate control nodes can increase installation workload and make troubleshooting more complicated.
The challenge is not simply connecting individual valves. It is creating a pneumatic control structure that can communicate efficiently with different PLC and automation platforms.
EV-FD Valve Terminals for Multi-Protocol Automation Integration
EV-FD Valve Terminals provide a bus-based pneumatic control solution designed to integrate multiple solenoid valves and communication functions within one modular platform.
Instead of controlling each valve through separate wiring, the valve terminal communicates directly with the automation control system through supported industrial networks.
This architecture can reduce the number of independent communication interfaces and simplify the connection between pneumatic actuators and the main PLC.
Supported Industrial Communication Protocols
One of the key advantages of the EV-FD platform is its support for multiple industrial communication protocols.
Depending on the system configuration, EV-FD Valve Terminals support communication options including:
- PROFINET
- EtherCAT
- EtherNet/IP
- IO-Link
- CC-Link IE Field Basic
This multi-protocol capability allows the valve terminal to be used with different PLC platforms and control architectures.
For machine builders and automation integrators working with equipment from several suppliers, selecting the appropriate communication module can reduce the need for additional protocol conversion devices.
Communication Performance for Complex Automation Systems
Communication speed is important when pneumatic actions must coordinate with sensors, PLC commands, conveyor movements, or other machine functions.
The EV-FD system supports data transmission speeds of up to 100 Mbps and communication distances of up to 100 meters, depending on the selected network configuration and installation conditions.
These specifications make the system suitable for many industrial automation layouts where valve terminals need to communicate with centralized controllers over industrial Ethernet networks.
Reliable communication helps maintain coordinated operation between pneumatic actuators and other automation components.
Modular Valve Island Design Simplifies System Architecture
Communication capability alone does not determine integration efficiency. Physical system structure also affects wiring, commissioning, and maintenance.
The EV-FD Valve Terminal adopts a modular valve island design that combines multiple solenoid valves and the communication module into one assembly.
This reduces the number of individually installed pneumatic control components and provides a more organized system layout.
For automation engineers, a centralized valve island can simplify cabinet design, pneumatic tubing arrangement, electrical connections, and system expansion.
Up to 24 Valve Stations for Centralized Control
The EV-FD system supports up to 24 valve stations, allowing multiple pneumatic channels to be managed from one valve terminal.
Centralized control is particularly useful in machines that contain several pneumatic cylinders or actuators operating in different process steps.
Typical examples include:
- Assembly stations
- Packaging machines
- Sorting systems
- Material handling equipment
- Conveyor automation
- Inspection equipment
- Pick-and-place systems
By grouping multiple pneumatic control points into one platform, the system can reduce the number of distributed valve nodes and make overall configuration easier to manage.
Pneumatic Performance for Automated Equipment
In addition to communication integration, the pneumatic capacity of the valve terminal must match the actuator requirements of the machine.
The EV-FD system supports a maximum flow rate of up to 600 L/min and an operating pressure range of 2–8 bar.
These specifications allow the valve terminal to support pneumatic actuators used in repetitive industrial automation applications.
When selecting a configuration, engineers should consider cylinder size, operating frequency, required response speed, tubing length, and simultaneous valve activation rather than relying only on maximum flow specifications.
Independent Coil Power Control
Electrical stability is another factor that can affect pneumatic valve operation.
Each solenoid valve in the EV-FD system uses independent coil power control. This design helps isolate individual valve actuation and supports more consistent operation when several valves are activated within the same system.
For machines with frequent switching cycles, stable coil control can contribute to predictable pneumatic response and easier system commissioning.
Flexible Installation and Future Expansion
EV-FD Valve Terminals support both DIN rail mounting and direct mounting, allowing the system to adapt to different control cabinet and machine layouts.
Standard pneumatic interfaces simplify air connections, while the modular architecture allows the number of valve stations or communication configuration to be adjusted according to equipment requirements.
This flexibility is useful for automation projects where system capacity may need to expand as additional actuators or machine functions are introduced.
Application in Malaysia Automation Systems
For machine builders and system integrators in Malaysia, EV-FD Valve Terminals can be used in automation projects where pneumatic control must communicate with different PLC platforms.
Typical applications include packaging equipment, assembly lines, material handling systems, electronic manufacturing equipment, semiconductor automation, sorting machines, and automated production cells.
The multi-protocol architecture is particularly useful when the automation system contains components from multiple suppliers and requires a standardized pneumatic control platform.
How to Select an EV-FD Communication Configuration
When selecting an EV-FD Valve Terminal for an automation project, the communication protocol should be matched to the PLC and network architecture already used in the machine.
Engineers should also confirm:
- Required industrial communication protocol
- PLC brand and controller interface
- Number of pneumatic control points
- Required valve station quantity
- Airflow demand of connected actuators
- Operating pressure
- Installation space
- Future expansion requirements
Checking these factors before configuration can help reduce unnecessary protocol conversion and simplify system commissioning.
Conclusion
Multi-vendor automation systems can create communication and integration challenges when pneumatic devices, PLCs, sensors, and other control components use different interfaces.
EV-FD Valve Terminals provide a modular pneumatic control platform supporting protocols such as PROFINET, EtherCAT, EtherNet/IP, IO-Link, and CC-Link IE Field Basic, together with transmission speeds of up to 100 Mbpsand support for up to 24 valve stations.
For automation systems in Malaysia, this architecture can provide a more structured way to integrate pneumatic control with different industrial networks while simplifying wiring, centralized control, installation, and future expansion.
