Basic Setup

In order to connect PLC to HMI or access the project in the PLC through Ethernet, it is used to assign an IP Address to the Ethernet Communication Module.

Applied Module : CM1-EC01A, CM1-EC10A, CM1-EC10B, CM1-EC10C, CM3-SP01EET.

Click Online -> Special Module Setup and choose Ethernet Module or click Ethernet module on the Card Properties.

If CPU is connected to CICON online, Base and Slot number display automatically.
If not, choose Base and Slot number where Ethernet module is installed.
Type IP Address, Subnet Mask and Gateway for your network.
If it is Modbus Slave, choose the Modbus Unit ID.
Click Write to save the data.

Notice
In case of expansion base, communication module is recommended to be installed in Local base.
If you need to install communication module in expansion base, only one communication module is recommended to be installed because communication speed (performance) should be decreasing.

 

DHCP Setup

To connect CIMON SCADA and PLC via dynamic IP(DHCP), CM1-EC10C can be used.

Choose the Base and Slot number where CM1-EC10C is installed.
Type System Name (Maximum 17characters).
The System name must be different for each module because CIMON SCADA will use this name to find out correct module.
Type IP address to DDNS #1 and Port number. If SCADA is configured redundancy system, type IP address to DDNS #1 and #2.
Both Port number must be the same with CIMON SCADA configuration.
Type DDNS Connection interval time. It is refresh time that PLC send its IP address to CIMON SCADA.
If it is too short, system should have heavy load and if it too long, recovery should be delayed.
10 to 60 seconds would be recommended.
Click Write.
