– When the mode is switched from RAM write mode to backup mode,
the parameters in the Operation/Adjustment groups (excluding
read-only parameters) are written to EEPROM.
– The RAM write mode is enabled only when the Communications
Writing parameter is set to “ON” (enabled). Consequently, when the
Communications Writing parameter setting is changed to “OFF”
(disabled), the parameters in the Operation/Adjustment groups
(excluding read-only parameters) are written to EEPROM even if the
mode is set to RAM write mode.
• Save RAM Data
This command writes the parameters in the Operation/Adjustment
groups (excluding read-only parameters) to EEPROM. The setting can
be accepted in both setup area 0 and setup area 1.
• Software Reset
Restarts processing from the point when power is turned ON. The
setting can be accepted in both setup area 0 and setup area 1.
• Move to Setup Area 1
This command moves to “setup area 1” and can be accepted at both
setup areas 0 and 1. If the “Initial Setting/Communications Protect”
parameter is set to “2,” an “operation error” will be generated, and the
move to setup area 1 will be prohibited.
When this move is carried out from setup area 0, the display indicates
the Input Type parameter in the “Initial Setting group.” When this
operation command is executed in setup area 1, the display will not
change.
• Move to Protect Group
This command moves to the “Protect group” 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 Group in Manual Mode
When this operation command is issued in manual mode, an
“operation error” will be generated, and the move to the Protect
group 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
manipulated variable” will be displayed. When the Controller is switched
from manual mode to automatic mode, the Operation group’s first
parameter will be displayed. When the Controller is switched to manual
