6.2.2

Creating a program for each slave station.

Create the program shown below for the communication test. (This program is not required during actual
operation.)
Determine the station number of each slave station, and then transfer a program corresponding to the station
number to each slave station.
Assign station numbers from "1" in the ascending order. (Use one station number only once. Do not skip
station numbers.)

Specify link device numbers for
other slave stations. (Do not specify
the device number (D10) for this
slave station.)
Cautions
1) When using a PLC (such as an FX
from slave stations to auxiliary relays (M), etc., and then monitor the auxiliary relays using a programming
tool. (Example: Change "K1Y004" to "K1M4".)
2) In the circuit from step 14, specify link devices for other slave stations.

6.2 Creating Programs for the Communication Testing
Set the slave station number to D8176.
The setting range is from K1 to K7.
When using ch1, this step is not required.
When using ch2, program "OUT M8179."

Step for writing information from a slave station (slave
station → master station)
Transfer the contents of X000 to X003 in this slave station
to a link device. The link device varies depending on the
station number.
The table below shows the link devices to be used:
Slave station No. Link device
1 D10
2 D20
3 D30
4 D40
5 D50
6 D60
7 D70
Step for reading information from the master station (master
station → slave station)
The contents of X000 to X003 in the master station are
transferred to outputs (Y) in this slave station.
Steps for reading information from another slave station
(another slave stations → this slave station)
By using link devices, read information from all other slave
stations.
The table below shows the link devices to be used:
Slave station No. Link device
