(1) Parameter change in program control function
Buffer memory settings can be changed and reflected to the control in
execution without stopping program control.
This function is enabled only when the bit 1 of the switch 3 is set to 1 (Enable)
in the intelligent function module switch setting. When the bit 1 of the switch 3 is
0 (Disable), and if a buffer memory setting is changed during program control, a
write data error occurs.
(2) Execution of the parameter change in program control function
When this function is enabled, control data, zone PID data, and pattern data
can be changed during program control. Turning Setting change command
(YnB) from off to on reflects the change to the control.
If a write data error occurs during setting change, the program control proceeds
with the setting before the change.
The buffer memory areas that can be changed are described under (a) to (c).
