What is a Virtual Local Area Network (VLAN)?
A virtual local area network (VLAN) segments a physical network into smaller, isolated networks. It can help improve security and performance on a network.
Layer 2 switches may create and segment VLANs but cannot route traffic between them, unless it has VLAN routing, or router-on-a-stick capabilities.
Layer 3 switches or routers perform routing between VLANs, enabling inter-VLAN communication.
VLANs are identified by VLAN IDs, ranging from 1 to 4095. When VLANs are enabled, a tag is applied to Ethernet frames. This tag encapsulates the data packet for proper VLAN identification.
How do I locate general network information and the IP Address on a Web HMI?
Device information for our Web HMIs, such as the Product Name, MAC Address, IP Address, Subnet Mask, and Default Gateway addresses, can be found in the 3rd menu tab on the left, after start up.

Design
What is a Web HMI?
Web HMIs (Human Machine Interfaces) are display units that use a Web Browser to act as a Web Client to visualize internal contents of PLCs and other devices. They offer a versatile and secure means to extend access to a central server. Especially designed for industrial applications, Web HMIs are durable, cost-effective, and user friendly, no communication cables needed, no programming software or programming hours spent.
Are your Web HMIs Class I, Div 2?
Our WP4000 series Web HMIs are C1D2 and our 10.1″ cMT Series Web HMI is ATEx rated.
What is a UDP Port?
A UDP port is a communication endpoint for transmitting data between devices on a network using the UDP protocol. On Maple Systems products, UDP ports enable fast, connectionless communication for applications like broadcast messaging or time-sensitive data transfers. Each port is identified by a unique number, ensuring multiple applications can operate without interference.
Commonly used UDP ports include 123 for NTP (Network Time Protocol) and 161 for SNMP (Simple Network Management Protocol). UDP is ideal for applications requiring low latency but does not guarantee data delivery. Always configure UDP ports according to your application’s requirements to ensure proper functionality and security.
What is a TCP Port?
A TCP port is a communication endpoint for transmitting data between devices on a network using the TCP protocol. On Maple Systems products, TCP ports facilitate connections between HMIs, PLCs, and other networked devices for data exchange and control. Each port is identified by a unique number, allowing multiple applications to run simultaneously on the same device.
Commonly used ports include 502 for Modbus TCP and 80 for web services, among others. Proper port configuration ensures seamless communication while minimizing the risk of unauthorized access or conflicts. Always verify port settings to match your application’s requirements and network policies.
What is a Layer 2 Network Switch?
A layer 2 network switch operates at the Data Link Layer of the OSI model. Click here for more information about the OSI Model. Layer 2 network switches forward data based on MAC addresses. They are responsible for directing traffic within a local area network (LAN).
Layer 2 switches do not inspect IP addresses, and their main focus is on MAC-level communication.
What is a Layer 3 Network Switch?
A layer 3 network switch operates at the Network Layer of the OSI model. Click here for more information about the OSI Model. Layer 3 network switches forward data based on IP addresses.
Unlike layer 2 network switches, layer 3 switches route traffic between different subnets. These switches combine the features of a traditional router and a layer 2 network switch. Layer 3 switches enable faster data forwarding with reduced latency compared to traditional routers.
What is the Open Systems Interconnection (OSI) model?
The Open Systems Interconnection (OSI) model is a reference model which describes seven layers of communication between computing systems over a network.
These seven layers are as outlined:
- Layer 1 – Physical: Converts signals back into data packets.
- example: Physical (Hardware/Cabling)
- Layer 2 – Data Link: Reassembles data packets
- example: Frames (MAC addresses)
- Layer 3 – Network: Ensures packets arrive correctly
- example: Packets (IP addresses)
- Layer 4 – Transport: Reorders packets if necessary
- Example: End-to-end connections (TCP, UDP)
- Layer 5 – Session: Maintains the session until the communication is complete
- example: Synchronization & Send to port (API’s, Sockets)
- Layer 6 – Presentation: Translates data into a format that the application layer can use
- example: Syntax Layer (SSL, SSH, FTP, IMAP etc)
- Layer 7 – Application: Delivers the data to the client
- example: End User Layer (HTTP, FTP, SSH)
The OSI model was developed by the International Organization for Standardization. It describes the tasks required to transmit data via radio waves, light, or electricity.
