Setup |
Not used. | |
Non-volatile memory within
EtherNet/IP Unit (See note.) |
The following settings are stored in the EtherNet/IP Unit’s non-volatile memory.
Note: Unlike the regular Ethernet Units, the CPU Bus Unit Setup Area in the CPU Unit is not used for these settings. 1. Unit setup (communications settings for the EtherNet/IP Unit, such as the IP address, DNS server settings, host name, baud rate, FINS/UDP settings, and FINS/ TCP settings) 2. Tag data link settings (device parameters) 3. User authentication settings (CS1W-EIP21S only) 4. Operation log (CS1W-EIP21S only) |
