Allow List Add/Edit MAC Address

Description

A MAC address (media access control) is an exclusive number assigned to each hardware network device. The number is unique and 48 bits in length. MAC addresses are displayed as 6 octets using Hexadecimal. The characters used are: 0-9, and A-F. The letters can be in Lower case or Upper case.

There are two methods of adding a MAC Address to the list: Single MAC, Range of MAC:

• Single MAC
• Range of MAC

 

Setup

Single MAC: Each individual device MAC can be specified.

Range of MAC: An inclusive range of MAC Addresses. The beginning and ending are specified arbitrarily.

Vendor MAC Prefix: Using the Range method can be particularly useful to easily include all devices of a specific Vendor. The first 3 octets represent the Vendor MAC Prefix. For Example, 00:D0:7C is used by all Koyo/JTEKT ELECTRONICS devices. The above configuration would allow all C-more and CLICK products to communicate with this PLC.

Finding your device MAC Address:

• CLICK CPUs show their MAC Address in the System Registers SD188-SD199, or also available in the Online Project Information.
• C-more HMI Panels display their MAC Address in the System Screen > Information > Ethernet, or also available in the software dialog, Panel > Panel Information > Ethernet
• DirectLogic, NetEdit Browse, or Product label.
• Do-more Designer, System Information > Serial Number, or Product label.
• Productivity Series, Choose CPU > CPU Connections, or using the onboard UIM Display.
• Other devices, after Enabling the Allow List, also “Enable Record Access other than Allow List”. When your device connection is rejected, check the Allow List Denied Records. The IP and MAC address of your device will be displayed in the list.
