1.
Check that RX[7B]: remote ready flag (*1) is set.
2.
Set the RY[0C]: command flag. This puts the communication unit in command mode, and
the RX[0C]: command flag is set. Clear sensor response data switching request flags other
than the command flag in advance.
3.
Set the RY[01]: write flag and activate Write mode.
4.
If the operation mode is CC-Link mode 1, set RY[10]: page 1. Page 1 setting is requested,
and RX[10]: page 1 is set. In CC-Link mode 1, always configure the page settings.
The page settings of the sensor response data (master unit, slave units 1 to 14) are as
shown in the table below.

5.
Specify the controller to which the command will be sent with RWw[00]: command request
sensor. When the operation mode is CC-Link mode 1, take care not to specify a command
request sensor outside the specified page setting range.
6.
Set the command code to be sent to RWw[01].
7.
Set the command data to be sent to RWw[02] to [09].
8.
Set RY[00]: send request flag and send the command. When command transmission is
completed, RX[00]: send done flag is set. Verify that RX[00]: send done flag is set, and then
proceed with the steps below.
9.
Verify that a communication error has not occurred with the RX[7A]: error status flag (*2)
cleared. If a communication error has occurred, refer to
10.
Verify that a command error has not occurred with the RX[01]: error flag cleared. If a com
-
mand error has occurred, refer to
.
11.
The value specified in step
5
(master unit, slave unit 1, slave unit 2, slave unit 3: 0x000F) is
set in RWr[00]: command response sensor. The command code sent to RWr[01] is stored.
12.
The RWr sensor response data is “0”.
13.
Clear RY[00]: send request flag. The communication unit ends command transmission, and
the RX[00]: send done flag is cleared.
14.
If the operation mode is CC-Link mode 1, clear RY[10]: page 1. Page 1 settings are
cleared, and RX[10]: page 1 is cleared.
15.
Clear RY[01]: write flag.
16.
Clear RY[0C]: command flag. The communication unit exits command mode, and RX[0C]:
command flag is cleared.
*1: The bit position depends on the operation mode.
CC-Link mode 1: RX[7B], CC-Link mode 2: RX[17B], CC-Link mode 3: RX[1BB]
*2: The bit position depends on the operation mode.
CC-Link mode 1: RX[7A], CC-Link mode 2: RX[17A], CC-Link mode 3: RX[1BA]
