The SECS/GEM communication software changes the communication settings when the setting request trigger is on, and
then switches off the setting request trigger.
Note that changes to the communication settings are applied the next time the SECS/GEM software is started.
When SECS/GEM communication software is started, the communication setting information set in the SECS/GEM
communication software pre-installed model module is stored in each piece of information of the communication settings.
Considerations
• Whether the settings are HSMS or SECS-, they are determined by "Port Type" at the "Communication Setting" screen
displayed by selecting [Settings]  [Communication Setting] in the menu.
• The communication settings are applied the next time the SECS/GEM software is started.
