SECTION 2 CompoWay/F Communications Procedures

Write mode
Backup mode The data is written to non-volatile memory when a
parameter in the operation, program setting, adjust-
ment, or PID setting level (excluding read-only
parameters) is written using communications.
RAM write mode The data is not written to non-volatile memory when
a parameter in the operation, program setting,
adjustment, or PID setting level (excluding read-only
parameters) is written using communications.
Parameters can be changed by using key operations
on the front panel of the Controller.
• When the mode is changed from RAM write mode to backup mode, the
parameters in the operation, program setting, adjustment, or PID
setting level (excluding read-only parameters) are written to non-volatile
memory.
• RAM write mode is enabled only when communications are enabled in
the Communications Writing parameter (i.e., set to ON). Therefore, if
the Communications Writing parameter is changed to OFF (disabled),
the parameter settings from the operation, program setting, adjustment,
and PID setting levels (excluding read-only parameters) are written to
non-volatile memory even if the RAM write mode is set.
● Save RAM Data
This command writes the parameters in the operation, program setting,
adjustment, or PID setting levels (excluding read-only parameters) to
non-volatile memory. The setting can be made in either setup area 0 or
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" 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 level." When this
operation command is executed in setup area 1, the display will not
change.
