Programless communication operating suggestions
Remind the suggestions below when executing the communication to the PLC.
(1) Set the device memory exists in the PLC by using the setting tool.
When setting the nonexistent device memory, the PLC sequence scan diminishes in speed.
(2) Set the PLC response monitoring time
5-15
to the value with enough margins in consideration for the PLC system
confi gurations. If the programless response monitoring time is short, the programless communication doses not operate
properly.
(3) Each demand fl ag in the setting area system fi eld should be modifi ed from the state that both of demand fl ag value and the
response fl ag value are “0000h”. Even if modifying from the state other than “0000h”, the demand fl ag commands are not
complied.
(4) When using 1:N connection, PLC communication setting
5-11
of every programless communication modules
should be the same. If not, a normal communication is not possible.
