5 COMMUNICATION PROCEDURE

POINT

To adjust settings with FX Configurator-EN (GX Developer), select “Initial Settings”
from the initial screen, and make the settings at the “Ethernet Initial Settings”
screen.

NOTE

(1) Set the value of each timer on the Ethernet module side such that the following

relations are met.

•

Response monitoring
timer value

TCP ULP
timer value

TCP end
timer value

TCP resend
timer value

IP assembly
timer value

•

TCP resend
timer value

TCP zero window
timer value

Furthermore, when connecting a line using Mitsubishi products, you should
make sure that both nodes have the same settings.

(2) Set the value of each timer on the external device side such way that the

following relations are met.
Communication errors such as transmission timeouts may occur more
frequently if the timer values are not set so that they satisfy the following
relationships.

•

TCP resend timer value on
the external device side

TCP resend timer value on
the external device side

•

Monitoring timer value for the
external device application software

* 1

*1 n is the number of TCP segment transmissions and can be obtained via the following calculation:

n

(fractions below decimal
point are rounded up)

Size of the message transmitted by the Ethernet module

Maximum segment size

TCP ULP timer value on
the Ethernet module side

n

Example1: Number of TCP segment transmissions when communicating via the

same line
The maximum segment size is 1460 bytes via the same line (without
going through a router) and the number of TCP segment
transmissions is as follows:
n = 1, if the size of the message transmitted by the Ethernet module

is 1460 bytes or less.

n = 2, if the size of the message transmitted by the Ethernet module

is greater than 1460 bytes.

Example2: Number of TCP segment transmissions when communicating via

separate lines
The maximum segment size is at least 536 bytes on a separate line
(via dialup router, etc.) and the number of TCP segment
transmissions is as follows:
n = 1, if the size of the message transmitted by the Ethernet module

is 536 bytes or less.

n = 2, if the size of the message transmitted by the Ethernet module

is greater than 536 bytes and no more than 1072 bytes.

n = 3, if the size of the message transmitted by the Ethernet module

is greater than 1072 bytes and no more than 1608 bytes.
