7.1 Error procedure
Troubles Causes Solutions
PWR indicator:
GREEN blinking
during 1:N connection
(0.1-sec inter-cycle)
PLC communication speed and
PLC communication data length is
mismatch
Check PLC communication speed setting/
PLC data length setting of the programless
communication module matches the
communication setting of PLC
The master station (St. No. "0") for
1:N connection is not connected
Connect the programless communication
module which St. No. is "0"
Only some programless
communication modules which are
connected during 1:N connection
cannot perform a programless
communication
There are some programless
communication modules that settings
below differ
PLC communication speed
PLC communication data length
MC protocol
PLC communication inter-cycle
time

Correct the set value with PUM parameter
loader and restart
Written value to PLC device
is sent to several programless
communication modules
With 1:N connection, the setting area
device memory setting of PLC is
duplicated
Make the setting area device memory
setting of each programless communication
module not to be duplicated
The value of Inter-PLC
communication execution time
monitor came to be extremely big
during 1:N connection
Other connected programless
communication modules were in the
communication error state (ex. break)
Restore the programless communication
module that is in the communication error
state, and restart
