It is important to understand IP addressing when connecting devices together over Ethernet.
Whether you are connecting a Maple Systems HMI or cMT to a PLC to communicate over Ethernet, or connecting your PC to an HMI to upload or download a project over Ethernet, you must know the IP addresses of all the devices in the local area network (LAN) to ensure successful communication.
In order for two devices to communicate over Ethernet, each device must have a unique IP address that is on the same subnet. Typically, this means that the first three octets of the IP address are the same and the last octet is unique and different.
Tech Note 5112, “IP Addressing (What's my IP?)” provides step-by-step instructions on setting up the IP Address on your Maple Systems HMI or cMT.
