Precautions for system register setting
- System register settings are effective from the time they are set. However, input settings, tool portico
port, and modem connection settings become effective when the mode is changed from PROG. to
RUN.
- With regard to the modem connection setting, when the power is turned off and on or when the mode is
changed from PROG. to RUN, the controller sends a command to the modem which enables it for
reception.
- When the initialized operation is performed, all set system register values (parameters) will be initialized
