PLC side settings

Configure the "S7-1500". The configuration is done using TIA (Totally Integrated Automation) Potal.

1.Starting a project for S7-1500
If you are creating a new project, place the units you want to use from "Device configuration" and configure them accordingly.
c_plc_0809

2.Select the Ethernet unit (in this case, the CPU, since we are using a CPU direct port) and display the properties.
c_plc_0810

3.Select "Ethernet addresses" from the properties and set the IP address from the setting screen.
c_plc_0811

setting	Setting contents
IP address	192.168.0.1
Subnet mask	255.255.255.0

4.Configure "Protection"
c_plc_0812

setting	Setting contents
Access level	Full access (no protection)
Connection mechanisms	Check it

5.Compile
c_plc_0813

6.Download the settings to PLC
c_plc_0814

In order to download the settings to CPU, you need to search for the Ethernet unit on "Online access" and connect to it.

PC settings

Use the Server application to connect to the PLC for which you have set up communications.

1.Right-click on "Application" - "Driver" in the tree and select Add Driver.

2.Select the following units from the displayed driver list and add them:
c_plc_0816

3.Open the properties of the added unit (U01) and click Communication Settings.
c_plc_0817

4.Configure the following in "PC Settings"
c_plc_0818

setting	Setting contents
Computer IP address	192.168.0.2
Computer port number	Automatic (Automatic because PLC cannot specify the communication port)

5.Set the following in "Unit side settings"
c_plc_0819

setting	Setting contents
Unit IP Address	192.168.0.1
Unit Port Number	102 (The destination port cannot be specified, so the default port of 102 is used.)

6.Select "Ping Test" to check if the ping goes through normally.
If you see a message like "Ping test is success～", the test was successful.

7.Under "Communication details" in the Communication details, set "CPU Slot" according to your environment.
c_plc_0820

setting

Setting contents

CPU Slot

1 (set according to your environment)

•For S7-300/400: "2"

•For S7-1200/1500: "1"

8.Perform a connection test to check the connection
c_plc_0821

If a message such as "Connection OK" is displayed, the connection is confirmed to be OK.
