Xpanel MODBUS Channel Configuration
When the MODBUS RTU feature is used in a project, you can check and set the related communication settings in the Xpanel device.
In the [Xpanel Config] window, select [Modbus] to bring up the [Modbus Channel Setting] window as shown below.
In the case of MODBUS TCP, the window will appear with all fields disabled, and the Xpanel device will communicate using the Ethernet IP address which is configured in the Ethernet Loader and Comm. Config. menus.
Configuration in CICON
After configuring Xpanel as a Modbus Slave in XpanelDesigner, you can connect to a CIMON-PLC which acts as a Modbus Master. Configuration for the PLC is performed in the CICON software package. The following is an example of a PLC-S configuration for this type of communication.
CICON Configuration
a) In CICON, create a project that uses a PLC-S CPU. Press [File] – [New Program] and select MODBUS/TCP Master. If you are using serial communication, select MOBUS/RTU Master.
b) Press [New] to configure the target device (Slave/Xpanel). Input the settings for IP address, Port Number, Timeout, and Status Code Device. Press [OK] to finish the configuration.
c) Press [Add] to add a communication block as shown below.
d) After adding a communication block, select [Tool] – [PLC Parameter], then go to the [Modbus] tab to set the Modbus device addresses for communication.
e) Go to the [Ethernet] tab to enter the IP configuration for the PLC. If you are using serial communication, go to the [Channel 1] or [Channel 2] tab instead.
