WebUsing Breakpoints¶ Breakpoints are commonly used for debugging programs. You can set breakpoints at specific positions in the program to force an execution stop and to monitor variable values. You can also set data breakpoints to halt program execution when the value of a specific variable changes. CODESYS supports breakpoints in all IEC editors. WebA MODBUS message sent from a master to a slave contains the address of the slave, the 'command' (e.g. 'read register' or 'write register'), the data, and a check sum (LRC or CRC). Since Modbus protocol is just a messaging structure, it is independent of the underlying physical layer. It is traditionally implemented using RS232, RS422, or RS485 namgate guest house namibia
