List of commands and responses used for serial communications in KV mode
Note 1: An underscore (_) in the command represents a space.
Note 2: M30 and TM31 are read-only memories; values cannot be written to them.
* The "WS" command changes the content of the program stored in the PLC's EEPROM. Contact if you
need to change it frequently.
