(4) Select Options

−

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 pro-

cedure. 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-T Controller Setup for the procedure to display parameters. (Refer to 7-1-3 E5

C-T

Controller 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-T Control-

lers 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 (E5CC-T) and set it to 2 for the No. 2 Controller.

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 PLC or set cmp for component

communications.)

Communications Unit No. (u-no): 0

Communications Baud Rate (bps): 57.6

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.

these Controllers will be reset.

(d) Confirm that the setting of the copy parameter on the No. 0 Controller changes

to off (i.e., copying completed), and then return the No. 0 Controller to the

operation level.
