4. 2. Setting the switch to change the communication (CN2SW)
Turn ON the communication switch (CN2SW) during Profibus control. If the communication switch
(CN2SW) is turned off during Profibus control, communication error (data link error) is generated in the
gateway unit. Turn OFF communication switch (CN2SW) when changing the setting of controller
(LEC) by connecting the teaching box (LEC-T1-) of setting software (LEC-W2) to PC/TB connector
(CN2). In this case, the communication from Profibus to the controller (LEC) is cut.

- 18 -
4. 3. Setting of controller (LEC)
Initial parameter setting is necessary for the controller (LEC) which is connected to the gateway unit.
Set the following by directly connecting the teaching box (LEC-T1-) or the setting software to the
controller (LEC) before connecting the gateway unit.
Check the operation manual of the controller (LEC) and the teaching box (LEC-T1-) when setting the
controller (LEC).
4. 3. 1 ID setting
ID setting is necessary when connecting two or more controllers (LEC) to the gateway unit.
Assign ID to each controller (LEC) in serial number so that the numbers do not overlap. The setting
range of ID is between 1 to 5.
[Example of ID change procedure using the ACT Controller Setting software (LEC-W2)]
Start the setting software in Normal mode.
Open the parameter window.
4. 3. 2 Setting of the communication speed
It is necessary to match the gateway unit controller IF communication speed with the controller (LEC)
communication speed. Set the controller IF communication speed at 115,2kbps to use the teaching
box (LEC-T1-)
[Communication speed change procedure Setting software (LEC-W2)]
Start the setting software with Normal mode.
(1) Select [HELP] - [Password] from the menu. Password input screen below appears. Enter "password".
(1) Set the controller ID.
(Letters are changed to blue)
