SJ-Ether Modbus/TCP communication（slave）
Question
I want to use Modbus/TCP communication with the SJ-Ether series as a slave station.
What should I do?
Answer
For details, see Chapter 4-4-4 Modbus/TCP Communication in the SJ-Ether User’s Manual.
The outline of the procedure for using SJ-Ether is as follows.
1.Set the IP address and subnet mask of SJ-Ether in Port3 of “PLC”-> “PLC Setup”-> “COM Port Setup” of KPP (Kostac PLC Programming software).
2.Check “Modbus/TCP Client-Server” for COM Port Setup.
3.Click “Modbus/TCP Client-Server”.
4.The client (master) settings may be the factory default values.
5.Set the TCP port number / timeout time in the server (slave) settings.
* SJ-Ether does not require a ladder program for data communication.
* For the master station settings, see the product manual of each company you are using.
* If there is a unit ID (slave ID) in the master station settings, set it to zero.
