Default Set value and explanation
0000H Set the base time for the no communication connection
detection timer value.
0000H : x 2 minutes
Other than 0000H : x 6 seconds
0000H Setting time = [Setting value (1 - FFFFH)] x [Base time]
- Set the time to detect a no-communication state after
connection establishment.
- The setting value of the above 208H is used as the base time.
- When the setting value is larger than 0064H,
in case of x 2 minutes : 200 minutes
in case of x 6 seconds : 10 minutes
000FH Setting time = [Set value (1 to FFFFH)] x 2 seconds
[30 seconds] - With TCP, this specifies the time that a packet exists when data
transmission, etc. is carried out.
0005H Setting time = [Set value (1 to FFFFH)] x 2 seconds
[10 seconds] - With TCP, this specifies the time until the receive window size
check packet is re-sent when the receive window size of the
other node becomes 0.
0005H Setting time = [Set value (1 to FFFFH)] x 2 seconds
[10 seconds] - With TCP, this specifies the time until data is re-sent if ACK is
not sent by the other node, when data transmission, etc. is
carried out.
0001H Setting time = [Set value (1 to FFFFH)] x 2 seconds
[2 seconds] - This specifies the time waited until open processing is carried
out when the same port is being re-opened, when TCP close
processing is done by the source node.
000FH Setting time = [Set value (1 to FFFFH)] x 2 seconds
[30 seconds] - This specifies the time waited for the next portion of data when
data split by the IP is being received.
- When any value is written, it should be 0000H.
