5.6.1 RESTART mode
The restart mode defines how to initialize variables and the system and how to operate in the RUN mode when the
system starts its operation with the RUN mode by re-application of the power or mode change. Two restart modes, cold
and warm restart are available and the execution condition for each restart mode is given below.
(For details, refer to the 4.5.1 Basic Parameters Edit’ of the GMWIN User’s Manual Section 4.5 Parameters Edit.)
1) Cold Restart
(1) It is executed when the restart mode parameter has been set to the cold restart mode.
(2) All data are cleared as ‘0’ and only variables of which initial value has been defined will be set as their initial value.
(3) Though the parameter has been set to the warm restart mode, cold restart will be executed at the first execution of a
program after it has been changed.
(4) In case of selection ‘Reset’ command in the GMWIN, it restarts in accordance with setting in parameter and in case of
selection ‘Overall Reset’ command; it restarts as cold restart mode.
2) Warm Restart
(1) It is executed when the restart mode parameter has been set to the warm restart mode.
(2) A data which set as retain & initial will be retain and a data which set as initial value will be set with default value during
the warm restart. All other data will be cleared with ‘0’.
(3) Though the parameter has been set to the warm restart mode, cold restart will be executed at the first execution of a
program after it has been stopped due to its down load and error.
(4) Though the parameter has been set to the warm restart mode, cold restart will be executed if data contents are
abnormal (i.e., the data does not remain at a power failure)
