ISPSoft User Manual (2) Type an IP address and a MAC address in the Static ARP Table window. Finally, click OK . Take the tables below for example. After the setting in the tables is downloaded to the CPU module, devices whose IP addresses are within the range between 192.168.1.1 and 192.168.1.50, and devices whose IP addresses are within the range between 192.168.1.100 and 192.168.1.150 are allowed to communicate with the CPU module if the CPU module operates. Besides, if the CPU module communicates with a device whose IP address of 192.168.1.20, the MAC address of the device must be BA:99:BA:14:BA:51.
Likewise, if the CPU module communicates with a device whose IP address is 192.168.1.21, the MAC address of the device must be 00:10:5A:81:CA:FD. *1. If users want to know the MAC address of a CPU module, they can click Online Mode in HWCONFIG to get the information about the CPU module connected and the status of the CPU module (section to view the information about the CPU module (section 3.8.6), or click System Information in ISPSoft 18.6.1). 3-174
