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.
