<Cautions on connection of two or more GOT units>
When two or more GOT units are connected to the FX/A/QnA Series PLC, communication is
performed in the location sequence from the GOT unit nearest to the CPU (that is, in the
sequence of the 1st, 2nd, 3rd and 4th GOT units). Accordingly, when turning on the power of
the GOT units for the first time, turn on the power from the one nearest to the CPU.
If the power cannot be turned on in the GOT units from the one nearest to the CPU, set the
GOT units (in "SET-UP MODE") or the screen creation software so that communication is per-
formed while the title screen display time is different by 2 to 3 seconds in each GOT unit.
FX/A/QnA Title screen display time (initial value: 4 sec)
1st GOT: 4 sec 2nd COT: 6 sec 3rd COT: 8 sec 4th COT: 10 sec
Setting example:The title screen display time is different by 2 seconds in each GOT unit, and
communication is started from the GOT unit nearest to the CPU.
* Perform the same setting without regard to the connection type (RS-232C or RS-422) of two
or more GOT units.
