• Parameters that cannot be set to local stations
Set the above-listed parameters that operate according to the settings of the master station in the master
station. To set other parameters, connect the Universal model QCPU with the master/local module and
configure the settings in the network parameter window of GX Works2.
(b) Precautions
• When the network configuration setting data exceeds the total number of slave stations
If the number of set network configuration setting data exceeds the total number of slave stations, the data
will be ignored. Only the data set within the total number of slave stations are valid.
• Applicable station numbers for reserved stations and error invalid stations
If the station number of a reserved station or error invalid station is outside the range set by total number of
slave stations and network configuration setting data, it is ignored. Only station numbers within the
specified ranges are valid.
• Parameter error
If a parameter error occurs, check the error code stored in buffer memory and link special register (SW)
and take corrective actions.
• Using a C Controller module on a local station
Disable "Block Data Assurance per Station" in the Network Parameter window for the master station.

Refresh Parameters
Not set
Since link refresh cannot be performed, directly access the buffer
memory in the master/local module.
Interrupt Settings
Not set (Interrupts cannot be performed.)
Interlink Transmission Parameters
Not set (Interlink transmission cannot be performed.)
Routing Parameters
Not set
Transient transmission that requires routing parameters cannot be
performed.
For whether routing parameters are needed, refer to the following.

If a parameter is incorrect, an error code (D824
H
or D825
H
) is stored in Parameter
communication result (buffer memory address: 31742 (7BFE
