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. You also cannot copy parameter settings to a Con-
troller with a version that is older than the version of the master. All of the slaves are automatically reset
after the copying operation is completed. Make sure that the system will not be adversely affected
before you copy parameter settings.
Communications Setting Level
Display condition: The Protocol Setting parameter must be set to
cmp
,
fins
, or
mcp4
and the Commu-
nications Unit No. parameter must be set to 0 (master).
Copying Procedure Starting from the Initial Status
(1) Connect the master and slaves with RS-485 connections and turn ON the power
supply.
For values other than the "Communications Unit No.", use the default value.
(Example: Protocol setting "cwf" communications baud rate "9.6")
(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 57.6, 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.
6-2-9 Copying Parameter Settings
Case in which copying
is possible
The model numbers and versions are the same.
Example: Copying data from the E5CC-TRX3ASM-002 (V1.0) to the
E5CC-TRX3ASM-002 (V1.0)
Cases in which copying
is not possible
The model numbers are different.
Example: Copying data from the E5CC-TRX3ASM-002 to the E5CC-TQX3ASM-002
The versions are different.
Example: Copying data from the E5CC-TRX3ASM-002 (V1.0) to the
E5CC-TRX3ASM-002 (V1.1)
