Details of the Local Station and TCP/IP Settings
Setting a Remote Station's Ethernet Address
When a remote station does not support the ARP (Address Resolution Protocol), use the fol-
lowing procedure to set a remote station's Ethernet address.
1. Move the cursor to the connection where the Ethernet address needs to be set.
Setting Item Details
Subnet Mask 1 Input a subnet mask for the local station's IP address. When the sub-
net mask is not being used, input 0 in fields 1 through 4.
Gateway IP Address 2 Input the gateway's IP address when transmitting data between con-
nected networks through a gateway (router).
The input ranges are different for each field of the gateway's IP
address:
• Field No. 1: 0 to 255 (excluding 127)
• Field No. 2: 0 to 255
• Field No. 3: 0 to 255
• Field No. 4: 1 to 254
If a gateway is not being used, input 0 in all four fields of the Gate-
way IP Address. When a gateway IP address is being input, be sure
not to duplicate any other IP address.
System Port No. Input the port number/engineering port (256 to 65,535) that receives
diagnostic commands from the diagnostic terminal.
TCP (Transmission
Control Protocol) Zero
Window Timer Value Input the retry time (1 to 255) for the Send Window confirmation
packet when the TCP's Send Window size is set to 0.
TCP Retry Time Input the time to wait (50 to 32,000 ms) before resending data when
an ACK (acknowledgment) is not received after opening a TCP con-
nection or transmitting data.
TCP Close Time Input the time to wait (1 to 255) for a remote station to completely
close the connection when a TCP connection is being closed.
IP Assemble Time Input the time to wait (1 to 255) for the next segment of data after the
IP has received a segment of data.
MAX. Packet 3 Length
Input the maximum packet length (64 to 1,500) in the 218IF.
1 Subnet Mask
The IP address is composed of a network address and a host address, but part of the host address can be
used as the network address. This is known as the subnet address and the bit pattern is known as the subnet
mask.
2 Gateway IP Address
Normally transmissions are relayed through a router when transmitting between different network address-
es. This router's IP address is known as the gateway address or default IP address.
3 Packet
A packet is a single segment of transmission data that has a destination address.
