Transfer to PLC
from the menu bar in the window that is shown
above. The settings will be transferred.
Close the window and cycle the power to the PLC. This completes the PLC setup
procedure. You will use the CX-Programmer to check operation, so leave it online.
This section describes the setup for programless communications (or components communications).
Refer to
6-2 E5

C Setup
for the procedure to display parameters. (Refer to
7-1-3 E5
@
C Setup
for
component communications as well.) Here we will assume that all parameters other than those for
communications have already been set. Make sure that all of the E5
@
C Controllers are the same
model. The parameter settings cannot be copied if the models are different.
(1) Set the Communications Unit No. parameter (
u-no
) in the communications setting
level to 1 for the No. 1 Controller and set it to 2 for the No. 2 Controller. Leave the
other communications settings at their default values.
The default communications unit number is 1, so the Communications Unit No. parameter
for the No. 1 Controller does not need to be changed.
Always set the communications unit numbers of the slaves in order from 1.
To enable the changes to the settings, always return to the operation level.
(2) Change the parameter settings in the communications setting level of the No. 0
Controller to the values that are given below.
Protocol Setting (
psel
):
fins
(Set
mcp4
for a Mitsubishi Q-series or L-series PLC,
fxp4
for a Mitsubishi FX-series or Keyence KV-series PLC, and
cmp
for
component communications.)
Communications Unit No. (
u-no
) : 0
Communications Baud Rate (
bps
) : 57.6 (Set 19.2 for a Mitsubishi FX1 or FX2 PLC and set
38.4 for a Mitsubishi FX3 PLC.)
Send Data Wait Time (
sdwt
): 1
Highest Communications Unit No. (
maxu
): 2
Do not return to the operation level even after you finish making the settings.
Here we will assume that all parameters other than those for communications have already
been set. If parameters other than those for communications need to be set, change them
first and then change the communications settings last.
(3) Perform the following procedure to copy the parameter settings in the No. 0
Controller to the No. 1 and No. 2 Controllers.
(a) Display the
copy
parameter in the communications setting level on the No. 0
Controller.
(b) Press the Up Key to select
all
and wait for three seconds. The completion of the
copy operation must be confirmed, so do not move to any other levels or param-
eters. If you do change to any other levels or parameters, display the
copy
parameter again.
(c) The PV displays on the No. 1 and No. 2 Controllers will change to
copy
and then
these Controllers will be reset.
