6 Programless Communications
Note: 1 If nothing is assigned for an upload setting, the corresponding address in the upload area will contain 0. If
nothing is assigned for a download setting, nothing will be done in the download area.
2 If the same value is set for more than one download setting, only the download setting with the lower
number will be valid. The other download setting will be treated as if nothing was assigned. All upload set-
tings are valid even if the same value is set more than once.
6-2-10 Copying Parameter Settings
You can copy the settings of all parameters except for the Communications Unit No. parameter from
the master (i.e., the Controller with communications unit number 0) to one or more of the slaves (i.e.,
the Controllers with communications unit numbers other than 0). Copying parameters is possible only
between Controllers with the same model number and the same version. The slaves to which the data
is copied are automatically reset after the copying operation is completed. Make sure that the system
will not be adversely affected before you copy parameter settings.

Copying Procedure Starting from the Initial Status
(1) Connect the master and slaves with RS-485 connections and turn ON the power
supply.
(2) Set the Communications Unit No. parameters of the slaves in order starting from 1
and then return to the operation level.
(3) Set all of the parameters in the master except for those in the communications
setting level.
(4) Change the master to the communications setting level and change the
communications settings as given below.
Change the Protocol Setting parameter, set the Communications Unit No. parameter to 0,
set the Communications Baud Rate parameter to 38.4 for a Mitsubishi FX3 PLC, and 115.2
for any other PLC, set the Send Data Wait Time parameter to 1, and set the Highest
Communications Unit No. parameter to the highest communications unit number that is set.
Change the other parameters in the communications setting level as required.
Do not return to the operation level while you are changing the parameter settings. If you
mistakenly return to the communications setting level, return the Communications Baud
Rate parameter to 9.6, return to the operation level, and then set the Communications Baud
Rate parameter again.

The model numbers and versions are the same.
Example:E5CD-RX2A6M-002(V1.1) → E5CD-RX2A6M-002(V1.1)
The model numbers are different.
Example:E5CD-RX2A6M-002 → E5CD-QX2A6M-002
The versions are different.
Example:E5CD-RX2A6M-002(V1.1) → E5CD-RX2A6M-002(V1.0)
