To disable internet access over the HMI’s ethernet port, set the gateway and DNS addresses of the WAN port you want to disable to 0.0.0.0 in the system settings for your device under the Ethernet…
Bridge Mode allows a device to function as a network switch, forwarding traffic between LAN ports without modifying packet data. This creates a seamless connection between devices, enabling communication as if they were on the…
Yes! You can have each LAN port on a cMT or HMI configured for a different network or subnet, in fact, we recommend doing so to keep the ports from conflicting. One thing to keep…
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…
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…
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…
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: The OSI model was developed by the…
TCP Connection Test:To use EasyAccess 2.0 VPN connection, multiple TCP connection would be made from your HMI or PC to our vpn servers. On PC, you can download our analyzer tool ea_connection_test.zip to check connections to those…
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…
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…
In a Server-Client topology, a client is a device or application that requests and utilizes services or resources provided by a server. The client initiates communication with the server, sending requests for data, processing, or…
An APIPA (Automatic Private IP Addressing) or Link-Local Address is a self-assigned IP address automatically generated by a device when it cannot obtain an IP address from a DHCP server. These addresses are in the…
