====== Interfacing with the CUBLOC ====== ===== Connect the CUBLOC MSB Series Products ===== Connect the ComfileHMI's RS-232 port to the MSB's RS-232 port as illustrated below. (The CUBLOC's built-in Modbus slave can only be used on the CUBLOC's serial channel 1.) {{ :comfilehmi:hmi_connection_cubloc:connectionmsb.png?nolink |}} {{ :comfilehmi:hmi_connection_cubloc:hmiwithplc.jpg?nolink&500 |}} ===== Connecting the CUBLOC CUSB Series Products ===== Connect the ComfileHMI's RS-232 port to the CUSB's RS-232 port as illustrated below. {{ :comfilehmi:hmi_connection_cubloc:connectioncusb.png?nolink |}} ===== Connecting the CUBLOC Core Module ===== The CUBLOC's 5V-level serial port must first be connected to a level shifter like the MAX232 to match the ComfileHMI's +/- 12V-level serial port. Some CUBLOC core modules already have a MAX232 built-in. {{ :comfilehmi:hmi_connection_cubloc:cubloccore_connection.png?nolink |}} ===== ComfileHMI's Communication Settings ====== When creating a new project, select the //COMFILE// and //CUBLOC MODBUS RTU// protocols. {{ :comfilehmi:hmi_connection_cubloc:eprj1.png?nolink |}} ====== Connecting via RS-485 ====== The ComfileHMI's RS-485 port can be connected to the CUBLOC's serial channel 1 through an RS-232 to RS-485 converter. {{ :comfilehmi:hmi_connection_cubloc:rs485cubloc.png?nolink |}} ====== CUBLOC Source Code ====== Please use CUBLOC Studio v4.0 or later. The following source code is a minimal Modbus slave implementation.


#include "MSB6XX"              ' MSB6XX Series device declaration. 
                               ' Core modules would use a declaration like Const Device = CB280

Set Modbus 1,1,100             ' Modbus RTU, slave address 1, frame delay 100 (approx. 10mS)
