1.
Check that RX[7B]: remote ready flag (*1) is set.
2.
Set RY[0C]: command flag and then check that RX[0C]: command flag is set. This changes
the mode to command mode. 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 settings are request-
ed, 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[0]: command request
sensor.
6.
Set the command code to be sent to RWw[1].
7.
Set the command data to be sent to RWw[2] to [9].
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.
Because a command error occurred, RX[01]: error flag is set. Among the RX[60] to [6F] error
output flags, the bit corresponding to the controller in which the error occurred is set at the
same time.
11.
The value specified in step
5
(master unit, slave unit 1, slave unit 2, slave unit 3: 0x000F) is
set in RWr[0]: command response sensor. The command code sent to RWr[1] is stored.
12.
The error code is stored in the sensor response data of the RWr that corresponds to the
controller in which the command error occurred.
13.
The sensor response data of RWr that correspond to controllers in which a command error
did not occur is "0".
14.
Clear RY[00]: send request flag. The communication unit ends command transmission, and
RX[00]: send done flag and RX[01]: error flag are cleared. RX[60] to [6F] error output flags
are also cleared.
15.
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.
16.
Clear RY[01]: write flag.
17.
Clear RY[0C]: command flag. The communication unit exits command mode, and RX[0C]:
command flag is cleared. After removing the cause of the error, re-execute the command.
*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]
