● Auto/Manual Switch
This operation command switches the mode to manual mode or
automatic mode, based on the related information setting. This
command can be accepted in setup area 0 only. An "operation error"
will be generated in the following instances:
• When the command is executed in "Setup Area 1"
• When auto/manual switching is disabled (not displayed)
When the Controller is switched to manual mode, the "manual manipu-
lated variable" will be displayed. When the Controller is switched from
manual mode to automatic mode, the operation level's first parameter
will be displayed. When the Controller is switched to manual mode
while already in manual mode, the command will be completed
normally and the display will not change (the contents will not be
refreshed).
◆ Writing Auto/Manual Status in EEPROM
The write mode determines whether the auto/manual status is written
to EEPROM.
Write mode
Backup mode
RAM write mode
Note: When the auto/manual mode is switched with an operation
command through communications and the Controller is in RAM
write mode, the auto/manual status is not stored in EEPROM.
Consequently, if the Controller is restar ted by performing a
software reset or turning the power OFF and ON again, the auto/
manual mode is set to the last saved status.
◆ Switching to Manual Mode during Auto-tuning
If the mode is switched during auto-tuning (AT), the AT will be
cancelled and the Controller will be switched to manual mode.
