SECTION 2 CompoWay/F Communications Procedures
2-18
● Move to Protect Level
This command moves to the “protect level” and can be accepted only in
setup area 0.When this command is issued in setup area 1, an
“operation error” will be generated, and the move to the protect level will
be prohibited.
◆ Moving to Protect Level in Manual Mode
When this operation command is issued in manual mode, an
“operation error” will be generated, and the move to the protect level
will be prohibited.
● 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.
* 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 restarted by performing a
software reset or turning the power OFF and ON again, the auto/
manual mode is set to the last saved status.
Write mode Description
Backup mode When the auto/manual mode is switched by
communications, the auto/manual status is writ-
ten to EEPROM.
RAM write mode When the auto/manual mode is switched by
communications, the auto/manual status is not
written to EEPROM.
The status can be written with the Controller
key operation.
